CVE-2026-33174 WRITEUP HIGH
Rails Active Storage has a possible DoS vulnerability when in proxy mode via Range requests
Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, when serving files through Active Storage's proxy delivery mode, the proxy controller loads the entire requested byte range into memory before sending it. A request with a large or unbounded Range header (e.g. `bytes=0-`) could cause the server to allocate memory proportional to the file size, possibly resulting in a DoS vulnerability through memory exhaustion. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.
CVSS 7.5
CVE-2026-33176 WRITEUP HIGH
Active Support <8.1.2.1 - DoS
Active Support is a toolkit of support libraries and Ruby core extensions extracted from the Rails framework. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Support number helpers accept strings containing scientific notation (e.g. `1e10000`), which `BigDecimal` expands into extremely large decimal representations. This can cause excessive memory allocation and CPU consumption when the expanded number is formatted, possibly resulting in a DoS vulnerability. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.
CVSS 7.5
CVE-2026-33195 WRITEUP CRITICAL
Active Storage <8.1.2.1, <8.0.4.1, <7.2.3.1 - Path Traversal
Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Storage's `DiskService#path_for` does not validate that the resolved filesystem path remains within the storage root directory. If a blob key containing path traversal sequences (e.g. `../`) is used, it could allow reading, writing, or deleting arbitrary files on the server. Blob keys are expected to be trusted strings, but some applications could be passing user input as keys and would be affected. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.
CVSS 9.8
CVE-2026-33202 WRITEUP CRITICAL
Active Storage <8.1.2.1 - Path Traversal
Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Storage's `DiskService#delete_prefixed` passes blob keys directly to `Dir.glob` without escaping glob metacharacters. If a blob key contains attacker-controlled input or custom-generated keys with glob metacharacters, it may be possible to delete unintended files from the storage directory. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.
CVSS 9.1
CVE-2026-33211 WRITEUP CRITICAL
Tekton Pipelines 1.0.0-1.10.2 - Path Traversal
Tekton Pipelines project provides k8s-style resources for declaring CI/CD-style pipelines. Starting in version 1.0.0 and prior to versions 1.0.1, 1.3.3, 1.6.1, 1.9.2, and 1.10.2, the Tekton Pipelines git resolver is vulnerable to path traversal via the `pathInRepo` parameter. A tenant with permission to create `ResolutionRequests` (e.g. by creating `TaskRuns` or `PipelineRuns` that use the git resolver) can read arbitrary files from the resolver pod's filesystem, including ServiceAccount tokens. The file contents are returned base64-encoded in `resolutionrequest.status.data`. Versions 1.0.1, 1.3.3, 1.6.1, 1.9.2, and 1.10.2 contain a patch.
CVSS 9.6
CVE-2026-27131 WRITEUP MEDIUM
Sprig Plugin for Craft CMS potentially discloses sensitive information via Sprig Playground
The Sprig Plugin for Craft CMS is a reactive Twig component framework for Craft CMS. Starting in version 2.0.0 and prior to versions 2.15.2 and 3.15.2, admin users, and users with explicit permission to access the Sprig Playground, could potentially expose the security key, credentials, and other sensitive configuration data, in addition to running the `hashData()` signing function. This issue was mitigated in versions 3.15.2 and 2.15.2 by disabling access to the Sprig Playground entirely when `devMode` is disabled, by default. It is possible to override this behavior using a new `enablePlaygroundWhenDevModeDisabled` that defaults to `false`.

CVE-2026-32913 WRITEUP CRITICAL
OpenClaw < 2026.3.7 - Custom Authorization Header Leakage via Cross-Origin Redirects
OpenClaw before 2026.3.7 contains an improper header validation vulnerability in fetchWithSsrFGuard that forwards custom authorization headers across cross-origin redirects. Attackers can trigger redirects to different origins to intercept sensitive headers like X-Api-Key and Private-Token intended for the original destination.
CVSS 9.3
CVE-2026-33316 WRITEUP HIGH
Vikunja’s Improper Access Control Enables Bypass of Administrator-Imposed Account Disablement
Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.0, a flaw in Vikunja’s password reset logic allows disabled users to regain access to their accounts. The `ResetPassword()` function sets the user’s status to `StatusActive` after a successful password reset without verifying whether the account was previously disabled. By requesting a reset token through `/api/v1/user/password/token` and completing the reset via `/api/v1/user/password/reset`, a disabled user can reactivate their account and bypass administrator-imposed account disablement. Version 2.2.0 patches the issue.

CVE-2026-33401 WRITEUP MEDIUM
Wallos: Incomplete fix for CVE-2026-30840 - SSRF in AI and notification endpoints bypass ssrf_helper.php
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.0, the patch introduced in commit e8a513591 (CVE-2026-30840) added SSRF protection to notification test endpoints but left three additional attack surfaces unprotected: the AI Ollama host parameter, the AI recommendations endpoint, and the notification cron job. An authenticated user can reach internal network services, cloud metadata endpoints (AWS IMDSv1, GCP, Azure IMDS), or localhost-bound services by supplying a crafted URL to any of these endpoints. This issue has been patched in version 4.7.0.
CVSS 6.5
CVE-2026-33517 WRITEUP MEDIUM
MantisBT Vulnerable to Stored HTML Injection in Tag Delete Confirmation
Mantis Bug Tracker (MantisBT) is an open source issue tracker. In version 2.28.0, when deleting a Tag (tag_delete.php), improper escaping of its name when displaying the confirmation message allows an attacker to inject HTML and, if CSP settings permit, achieve execution of arbitrary JavaScript. Version 2.28.1 fixes the issue. Workarounds include reverting commit d6890320752ecf37bd74d11fe14fe7dc12335be9 and/or manually editing language files to remove the sprintf placeholder `%1$s` from `$s_tag_delete_message` string.
CVSS 6.1
CVE-2026-33634 WRITEUP HIGH
Trivy ecosystem supply chain briefly compromised
Trivy is a security scanner. On March 19, 2026, a threat actor used compromised credentials to publish a malicious Trivy v0.69.4 release, force-push 76 of 77 version tags in `aquasecurity/trivy-action` to credential-stealing malware, and replace all 7 tags in `aquasecurity/setup-trivy` with malicious commits. This incident is a continuation of the supply chain attack that began in late February 2026. Following the initial disclosure on March 1, credential rotation was performed but was not atomic (not all credentials were revoked simultaneously). The attacker could have use a valid token to exfiltrate newly rotated secrets during the rotation window (which lasted a few days). This could have allowed the attacker to retain access and execute the March 19 attack. Affected components include the `aquasecurity/trivy` Go / Container image version 0.69.4, the `aquasecurity/trivy-action` GitHub Action versions 0.0.1 – 0.34.2 (76/77), and the`aquasecurity/setup-trivy` GitHub Action versions 0.2.0 – 0.2.6, prior to the recreation of 0.2.6 with a safe commit. Known safe versions include versions 0.69.2 and 0.69.3 of the Trivy binary, version 0.35.0 of trivy-action, and version 0.2.6 of setup-trivy. Additionally, take other mitigations to ensure the safety of secrets. If there is any possibility that a compromised version ran in one's environment, all secrets accessible to affected pipelines must be treated as exposed and rotated immediately. Check whether one's organization pulled or executed Trivy v0.69.4 from any source. Remove any affected artifacts immediately. Review all workflows using `aquasecurity/trivy-action` or `aquasecurity/setup-trivy`. Those who referenced a version tag rather than a full commit SHA should check workflow run logs from March 19–20, 2026 for signs of compromise. Look for repositories named `tpcp-docs` in one's GitHub organization. The presence of such a repository may indicate that the fallback exfiltration mechanism was triggered and secrets were successfully stolen. Pin GitHub Actions to full, immutable commit SHA hashes, don't use mutable version tags.

CVE-2026-33668 WRITEUP HIGH
Vikunja Allows Disabled/Locked User Accounts to Authenticate via API Tokens, CalDAV, and OpenID Connect
Vikunja is an open-source self-hosted task management platform. Starting in version 0.18.0 and prior to version 2.2.1, when a user account is disabled or locked, the status check is only enforced on the local login and JWT token refresh paths. Three other authentication paths — API tokens, CalDAV basic auth, and OpenID Connect — do not verify user status, allowing disabled or locked users to continue accessing the API and syncing data. Version 2.2.1 patches the issue.
CVSS 8.1
CVE-2026-29111 WRITEUP MEDIUM
systemd v239-v249 - Memory Corruption
systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions older than that are not affected. Versions 260-rc1, 259.2, 258.5, and 257.11 contain patches. No known workarounds are available.
CVSS 5.5
CVE-2026-32948 WRITEUP HIGH
sbt: Source dependency feature (via crafted VCS URL) leads to arbitrary code execution on Windows
sbt is a build tool for Scala, Java, and others. From version 0.9.5 to before version 1.12.7, on Windows, sbt uses Process("cmd", "/c", ...) to run VCS commands (git, hg, svn). The URI fragment (branch, tag, revision) is user-controlled via the build definition and passed to these commands without validation. Because cmd /c interprets &, |, and ; as command separators, a malicious fragment can execute arbitrary commands. This issue has been patched in version 1.12.7.
CVSS 7.8
CVE-2026-33323 WRITEUP MEDIUM
Parse Server: Email verification resend page leaks user existence
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.51 and 9.6.0-alpha.40, the Pages route and legacy PublicAPI route for resending email verification links return distinguishable responses depending on whether the provided username exists and has an unverified email. This allows an unauthenticated attacker to enumerate valid usernames by observing different redirect targets. The existing emailVerifySuccessOnInvalidEmail configuration option, which is enabled by default and protects the API route against this, did not apply to these routes. This issue has been patched in versions 8.6.51 and 9.6.0-alpha.40.
CVSS 5.3
CVE-2026-33409 WRITEUP CRITICAL
Parse Server: Auth provider validation bypass on login via partial authData
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.52 and 9.6.0-alpha.41, an authentication bypass vulnerability allows an attacker to log in as any user who has linked a third-party authentication provider, without knowing the user's credentials. The attacker only needs to know the user's provider ID to gain full access to their account, including a valid session token. This affects Parse Server deployments where the server option allowExpiredAuthDataToken is set to true. The default value is false. This issue has been patched in versions 8.6.52 and 9.6.0-alpha.41.
CVSS 9.1
CVE-2026-33421 WRITEUP MEDIUM
Parse Server: LiveQuery bypasses CLP pointer permission enforcement
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.53 and 9.6.0-alpha.42, Parse Server's LiveQuery WebSocket interface does not enforce Class-Level Permission (CLP) pointer permissions (readUserFields and pointerFields). Any authenticated user can subscribe to LiveQuery events and receive real-time updates for all objects in classes protected by pointer permissions, regardless of whether the pointer fields on those objects point to the subscribing user. This bypasses the intended read access control, allowing unauthorized access to potentially sensitive data that is correctly restricted via the REST API. This issue has been patched in versions 8.6.53 and 9.6.0-alpha.42.
CVSS 6.5
CVE-2026-33429 WRITEUP MEDIUM
Parse Server: Protected field change detection oracle via LiveQuery watch parameter
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.54 and 9.6.0-alpha.43, an attacker can subscribe to LiveQuery with a watch parameter targeting a protected field. Although the protected field value is properly stripped from event payloads, the presence or absence of update events reveals whether the protected field changed, creating a binary oracle. For boolean protected fields, the timing of change events is equivalent to knowing the field value. This issue has been patched in versions 8.6.54 and 9.6.0-alpha.43.
CVSS 5.3
CVE-2026-33498 WRITEUP HIGH
Parse Server: Query condition depth bypass via pre-validation transform pipeline
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.55 and 9.6.0-alpha.44, an attacker can send an unauthenticated HTTP request with a deeply nested query containing logical operators to permanently hang the Parse Server process. The server becomes completely unresponsive and must be manually restarted. This is a bypass of the fix for CVE-2026-32944. This issue has been patched in versions 8.6.55 and 9.6.0-alpha.44.
CVSS 7.5
CVE-2026-33508 WRITEUP HIGH
Parse Server: LiveQuery subscription query depth bypass
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.56 and 9.6.0-alpha.45, Parse Server's LiveQuery component does not enforce the requestComplexity.queryDepth configuration setting when processing WebSocket subscription requests. An attacker can send a subscription with deeply nested logical operators, causing excessive recursion and CPU consumption that degrades or disrupts service availability. This issue has been patched in versions 8.6.56 and 9.6.0-alpha.45.
CVSS 7.5
CVE-2026-33527 WRITEUP MEDIUM
Parse Server: Session update endpoint allows overwriting server-generated session fields
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.57 and 9.6.0-alpha.48, an authenticated user can overwrite server-generated session fields such as expiresAt and createdWith when updating their own session via the REST API. This allows bypassing the server's configured session lifetime policy, making a session effectively permanent. This issue has been patched in versions 8.6.57 and 9.6.0-alpha.48.
CVSS 4.3
CVE-2026-33538 WRITEUP HIGH
Parse Server: Denial of service via unindexed database query for unconfigured auth providers
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.58 and 9.6.0-alpha.52, an unauthenticated attacker can cause denial of service by sending authentication requests with arbitrary, unconfigured provider names. The server executes a database query for each unconfigured provider before rejecting the request, and since no database index exists for unconfigured providers, each request triggers a full collection scan on the user database. This can be parallelized to saturate database resources. This issue has been patched in versions 8.6.58 and 9.6.0-alpha.52.
CVSS 7.5
CVE-2026-33539 WRITEUP HIGH
Parse Server: SQL injection via aggregate and distinct field names in PostgreSQL adapter
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.59 and 9.6.0-alpha.53, an attacker with master key access can execute arbitrary SQL statements on the PostgreSQL database by injecting SQL metacharacters into field name parameters of the aggregate $group pipeline stage or the distinct operation. This allows privilege escalation from Parse Server application-level administrator to PostgreSQL database-level access. Only Parse Server deployments using PostgreSQL are affected. MongoDB deployments are not affected. This issue has been patched in versions 8.6.59 and 9.6.0-alpha.53.
CVSS 7.2
CVE-2026-33624 WRITEUP LOW
Parse Server: MFA recovery code single-use bypass via concurrent requests
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.60 and 9.6.0-alpha.54, an attacker who obtains a user's password and a single MFA recovery code can reuse that recovery code an unlimited number of times by sending concurrent login requests. This defeats the single-use design of recovery codes. The attack requires the user's password, a valid recovery code, and the ability to send concurrent requests within milliseconds. This issue has been patched in versions 8.6.60 and 9.6.0-alpha.54.
CVSS 2.7
