CVE-2026-4519 WRITEUP LOW
webbrowser.open() allows leading dashes in URLs
The webbrowser.open() API would accept leading dashes in the URL which could be handled as command line options for certain web browsers. New behavior rejects leading dashes. Users are recommended to sanitize URLs prior to passing to webbrowser.open().
CVSS 3.3
CVE-2026-30932 WRITEUP HIGH
Froxlor is vulnerable to BIND zone file injection via unsanitized DNS record content in DomainZones API
Froxlor is open source server administration software. Prior to version 2.3.5, the DomainZones.add API endpoint (accessible to customers with DNS enabled) does not validate the content field for several DNS record types (LOC, RP, SSHFP, TLSA). An attacker can inject newlines and BIND zone file directives (e.g. $INCLUDE) into the zone file that gets written to disk when the DNS rebuild cron job runs. This issue has been patched in version 2.3.5.
CVSS 8.8
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-2026-33329 WRITEUP HIGH
FileRise: Path Traversal in `resumableIdentifier` Leading to Arbitrary File Write, Recursive Directory Deletion, and Limited Existence Oracle
FileRise is a self-hosted web file manager / WebDAV server. From version 1.0.1 to before version 3.10.0, the resumableIdentifier parameter in the Resumable.js chunked upload handler (UploadModel::handleUpload()) is concatenated directly into filesystem paths without any sanitization. An authenticated user with upload permission can exploit this to write files to arbitrary directories on the server, delete arbitrary directories via the post-assembly cleanup, and probe file/directory existence. This issue has been patched in version 3.10.0.
CVSS 8.1
CVE-2026-33330 WRITEUP HIGH
FileRise ONLYOFFICE integration allows read-only users to overwrite files via forged save callback
FileRise is a self-hosted web file manager / WebDAV server. Prior to version 3.10.0, a broken access control issue in FileRise's ONLYOFFICE integration allows an authenticated user with read-only access to obtain a signed save callbackUrl for a file and then directly forge the ONLYOFFICE save callback to overwrite that file with attacker-controlled content. This issue has been patched in version 3.10.0.
CVSS 7.1
CVE-2026-33331 WRITEUP HIGH
oRPC: Stored XSS in OpenAPI Reference Plugin via unescaped JSON.stringify
oRPC is an tool that helps build APIs that are end-to-end type-safe and adhere to OpenAPI standards. Prior to version 1.13.9, a stored cross-site scripting (XSS) vulnerability exists in the OpenAPI documentation generation of orpc. If an attacker can control any field within the OpenAPI specification (such as info.description), they can break out of the JSON context and execute arbitrary JavaScript when a user views the generated API documentation. This issue has been patched in version 1.13.9.
CVSS 8.2
CVE-2026-33332 WRITEUP HIGH
NiceGUI's unvalidated chunk size parameter in media routes can cause memory exhaustion
NiceGUI is a Python-based UI framework. Prior to version 3.9.0, NiceGUI's app.add_media_file() and app.add_media_files() media routes accept a user-controlled query parameter that influences how files are read during streaming. The parameter is passed to the range-response implementation without validation, allowing an attacker to bypass chunked streaming and force the server to load entire files into memory at once. With large media files and concurrent requests, this can lead to excessive memory consumption, degraded performance, or denial of service. This issue has been patched in version 3.9.0.
CVSS 7.5
CVE-2026-33344 WRITEUP HIGH
Dagu has an incomplete fix for CVE-2026-27598: path traversal via %2F-encoded slashes in locateDAG
Dagu is a workflow engine with a built-in Web user interface. From version 2.0.0 to before version 2.3.1, the fix for CVE-2026-27598 added ValidateDAGName to CreateNewDAG and rewrote generateFilePath to use filepath.Base. This patched the CREATE path. The remaining API endpoints - GET, DELETE, RENAME, EXECUTE - all pass the {fileName} URL path parameter to locateDAG without calling ValidateDAGName. %2F-encoded forward slashes in the {fileName} segment traverse outside the DAGs directory. This issue has been patched in version 2.3.1.
CVSS 8.1
CVE-2026-33345 WRITEUP MEDIUM
solidtime vulnerable to IDOR in private projects
solidtime is an open-source time-tracking app. Prior to version 0.11.6, the project detail endpoint GET /api/v1/organizations/{org}/projects/{project} allows any authenticated Employee to access any project in the organization by UUID, including private projects they are not a member of. The index() endpoint correctly applies the visibleByEmployee() scope, but show() does not. This issue has been patched in version 0.11.6.
CVSS 6.5
CVE-2026-33347 WRITEUP MEDIUM
league/commonmark has an embed extension allowed_domains bypass
league/commonmark is a PHP Markdown parser. From version 2.3.0 to before version 2.8.2, the DomainFilteringAdapter in the Embed extension is vulnerable to an allowlist bypass due to a missing hostname boundary assertion in the domain-matching regex. An attacker-controlled domain like youtube.com.evil passes the allowlist check when youtube.com is an allowed domain. This issue has been patched in version 2.8.2.
CVSS 6.1
CVE-2026-33349 WRITEUP MEDIUM
fast-xml-parser: Entity Expansion Limits Bypassed When Set to Zero Due to JavaScript Falsy Evaluation
fast-xml-parser allows users to process XML from JS object without C/C++ based libraries or callbacks. From version 4.0.0-beta.3 to before version 5.5.7, the DocTypeReader in fast-xml-parser uses JavaScript truthy checks to evaluate maxEntityCount and maxEntitySize configuration limits. When a developer explicitly sets either limit to 0 — intending to disallow all entities or restrict entity size to zero bytes — the falsy nature of 0 in JavaScript causes the guard conditions to short-circuit, completely bypassing the limits. An attacker who can supply XML input to such an application can trigger unbounded entity expansion, leading to memory exhaustion and denial of service. This issue has been patched in version 5.5.7.
CVSS 5.9
CVE-2026-33353 WRITEUP MEDIUM
Soft Serve: Authenticated repo import can clone server-local private repositories
Soft Serve is a self-hostable Git server for the command line. From version 0.6.0 to before version 0.11.6, an authorization flaw in repo import allows any authenticated SSH user to clone a server-local Git repository, including another user's private repo, into a new repository they control. This issue has been patched in version 0.11.6.
CVSS 6.5
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-2026-33412 WRITEUP MEDIUM
Vim affected by Command injection via newline in glob()
Vim is an open source, command line text editor. Prior to version 9.2.0202, a command injection vulnerability exists in Vim's glob() function on Unix-like systems. By including a newline character (\n) in a pattern passed to glob(), an attacker may be able to execute arbitrary shell commands. This vulnerability depends on the user's 'shell' setting. This issue has been patched in version 9.2.0202.
CVSS 5.6
CVE-2026-33417 WRITEUP MEDIUM
Wallos: Password Reset Tokens Never Expire
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.2, password reset tokens in Wallos never expire. The password_resets table includes a created_at timestamp column, but the token validation logic never checks it. A password reset token remains valid indefinitely until it is used, allowing an attacker who intercepts a reset link at any point to use it days, weeks, or months later. This issue has been patched in version 4.7.2.
CVSS 6.5
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.
