CVE-2026-34161 WRITEUP MEDIUM
Chamilo LMS: Stored XSS via Malicious File Upload in Social Post Attachments Leads to Arbitrary JavaScript Execution
Chamilo LMS is an open-source learning management system. In versions prior to 2.0.0-RC.3, a Stored Cross-Site Scripting (XSS) vulnerability exists in the social post attachment upload functionality, where an authenticated user can upload a malicious HTML file containing JavaScript via the /api/social_post_attachments endpoint. The uploaded file is served back from the application at the generated contentUrl without sanitization, content type restrictions, or a Content-Disposition: attachment header, causing the JavaScript to execute in the browser within the application's origin. Because the payload is stored server-side and runs in the trusted origin, an attacker can perform session hijacking, account takeover, privilege escalation (if an admin views the link), and arbitrary actions on behalf of the victim. This issue has been fixed in version 2.0.0-RC.3.
CVSS 5.4
CVE-2026-34602 WRITEUP HIGH
Chamilo LMS: IDOR in /api/course_rel_users Allows Unauthorized Enrollment of Arbitrary Users into Courses
Chamilo LMS is an open-source learning management system. In versions prior to 2.0.0-RC.3, the /api/course_rel_users endpoint is vulnerable to Insecure Direct Object Reference (IDOR), allowing an authenticated attacker to modify the user parameter in the request body to enroll any arbitrary user into any course without proper authorization checks. The backend trusts the user-supplied input for the user field and performs no server-side verification that the requester owns the referenced user ID or has permission to act on behalf of other users. This enables unauthorized manipulation of user-course relationships, potentially granting unintended access to course materials, bypassing enrollment controls, and compromising platform integrity. This issue has been fixed in version 2.0.0-RC.3.
CVSS 7.1
CVE-2026-1555 WRITEUP CRITICAL
WebStack <= 1.2024 - Unauthenticated Arbitrary File Upload
The WebStack theme for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the io_img_upload() function in all versions up to, and including, 1.2024. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
CVSS 9.8
CVE-2025-14813 WRITEUP CRITICAL

CVE-2026-33888 WRITEUP MEDIUM
ApostropheCMS: publicApiProjection Bypass via `project` Query Builder in Piece-Type REST API
ApostropheCMS is an open-source Node.js content management system. Versions 4.28.0 and prior contain an authorization bypass vulnerability in the getRestQuery method of the @apostrophecms/piece-type module, where the method checks whether a MongoDB projection has already been set before applying the admin-configured publicApiProjection. An unauthenticated attacker can supply a project query parameter in the REST API request, which is processed by applyBuildersSafely before the permission check, pre-populating the projection state and causing the publicApiProjection to be skipped entirely. This allows disclosure of any field on publicly queryable documents that the administrator explicitly restricted from the public API, such as internal notes, draft content, or metadata. Exploitation is trivial, requiring only appending query parameters to a public URL with no authentication. This issue has been fixed in version 4.29.0.
CVSS 5.3
CVE-2026-35569 WRITEUP HIGH
ApostropheCMS: Stored XSS in SEO Fields Leads to Authenticated API Data Exposure in ApostropheCMS
ApostropheCMS is an open-source Node.js content management system. Versions 4.28.0 and prior contain a stored cross-site scripting vulnerability in SEO-related fields (SEO Title and Meta Description), where user-controlled input is rendered without proper output encoding into HTML contexts including <title> tags, <meta> attributes, and JSON-LD structured data. An attacker can inject a payload such as "></title><script>alert(1)</script> to break out of the intended HTML context and execute arbitrary JavaScript in the browser of any authenticated user who views the affected page. This can be leveraged to perform authenticated API requests, access sensitive data such as usernames, email addresses, and roles via internal APIs, and exfiltrate it to an attacker-controlled server. This issue has been fixed in version 4.29.0.
CVSS 8.7
CVE-2026-40959 WRITEUP CRITICAL

Luanti <5.15.2 - Privilege Escalation
Luanti 5 before 5.15.2 sometimes allows unintended access to an insecure environment. If at least one mod is listed as secure.trusted_mods or secure.http_mods, then a crafted mod can intercept the request for the insecure environment or HTTP API, and also receive access to it.
CVSS 8.1
CVE-2026-41015 WRITEUP HIGH
radare2 - Command Injection
radare2 before 9236f44, when configured on UNIX without SSL, allows command injection via a PDB name to rabin2 -PP. NOTE: although users are supposed to use the latest version from git (not a release), the date range for the vulnerable code was less than a week, occurring after 6.1.2 but before 6.1.3.
CVSS 7.4
CVE-2026-31843 WRITEUP CRITICAL
Goodoneuz Pay-uz < <= 2.2.24 - Remote Code Execution
The goodoneuz/pay-uz Laravel package (<= 2.2.24) contains a critical vulnerability in the /payment/api/editable/update endpoint that allows unauthenticated attackers to overwrite existing PHP payment hook files. The endpoint is exposed via Route::any() without authentication middleware, enabling remote access without credentials. User-controlled input is directly written into executable PHP files using file_put_contents(). These files are later executed via require() during normal payment processing workflows, resulting in remote code execution under default application behavior. The payment secret token mentioned by the vendor is unrelated to this endpoint and does not mitigate the vulnerability.
CVSS 9.8
CVE-2025-70795 WRITEUP MEDIUM
STProcessMonitor 11.11.4.0 - DoS
STProcessMonitor 11.11.4.0, part of the Safetica Application suite, allows an admin-privileged user to send crafted IOCTL requests to terminate processes that are protected through a third-party implementation. This is caused by insufficient caller validation in the driver's IOCTL handler, enabling unauthorized processes to perform those actions in kernel space. Successful exploitation can lead to denial of service by disrupting critical third-party services or applications. Unauthorized processes load the driver and send a crafted IOCTL request (0xB822200C) to terminate processes protected by a third-party implementation. This action exploits insufficient caller validation in the driver's IOCTL handler, allowing unauthorized processes to perform termination operations in kernel space. Successful exploitation can lead to denial of service by disrupting critical third-party services or applications.
CVSS 5.5
CVE-2026-31317 WRITEUP HIGH
Craftql <=1.3.7 - SSRF
Craftql v1.3.7 and before is vulnerable to Server-Side Request Forgery (SSRF) which allows an attacker to execute arbitrary code via the vendor/markhuot/craftql/src/Listeners/GetAssetsFieldSchema.php file
CVSS 7.5
CVE-2026-40324 WRITEUP CRITICAL
Hot Chocolate's Utf8GraphQLParser has Stack Overflow via Deeply Nested GraphQL Documents
Hot Chocolate is an open-source GraphQL server. Prior to versions 12.22.7, 13.9.16, 14.3.1, and 15.1.14, Hot Chocolate's recursive descent parser `Utf8GraphQLParser` has no recursion depth limit. A crafted GraphQL document with deeply nested selection sets, object values, list values, or list types can trigger a `StackOverflowException` on payloads as small as 40 KB. Because `StackOverflowException` is uncatchable in .NET (since .NET 2.0), the entire worker process is terminated immediately. All in-flight HTTP requests, background `IHostedService` tasks, and open WebSocket subscriptions on that worker are dropped. The orchestrator (Kubernetes, IIS, etc.) must restart the process. This occurs before any validation rules run — `MaxExecutionDepth`, complexity analyzers, persisted query allow-lists, and custom `IDocumentValidatorRule` implementations cannot intercept the crash because `Utf8GraphQLParser.Parse` is invoked before validation. The `MaxAllowedFields=2048` limit does not help because the crashing payloads contain very few fields. The fix in versions 12.22.7, 13.9.16, 14.3.1, and 15.1.14 adds a `MaxAllowedRecursionDepth` option to `ParserOptions` with a safe default, and enforces it across all recursive parser methods (`ParseSelectionSet`, `ParseValueLiteral`, `ParseObject`, `ParseList`, `ParseTypeReference`, etc.). When the limit is exceeded, a catchable `SyntaxException` is thrown instead of overflowing the stack. There is no application-level workaround. `StackOverflowException` cannot be caught in .NET. The only mitigation is to upgrade to a patched version. Operators can reduce (but not eliminate) risk by limiting HTTP request body size at the reverse proxy or load balancer layer, though the smallest crashing payload (40 KB) is well below most default body size limits and is highly compressible (~few hundred bytes via gzip).
CVSS 9.1
CVE-2026-5720 WRITEUP CRITICAL
miniupnpd Integer Underflow SOAPAction Header Parsing
miniupnpd contains an integer underflow vulnerability in SOAPAction header parsing that allows remote attackers to cause a denial of service or information disclosure by sending a malformed SOAPAction header with a single quote. Attackers can trigger an out-of-bounds memory read by exploiting improper length validation in ParseHttpHeaders(), where the parsed length underflows to a large unsigned value when passed to memchr(), causing the process to scan memory far beyond the allocated HTTP request buffer.
CVSS 9.1
CVE-2026-35465 WRITEUP HIGH
SecureDrop Client has path injection in read_gzip_header_filename()
SecureDrop Client is a desktop app for journalists to securely communicate with sources and handle submissions on the SecureDrop Workstation. In versions 0.17.4 and below, a compromised SecureDrop Server can achieve code execution on the Client's virtual machine (sd-app) by exploiting improper filename validation in gzip archive extraction, which permits absolute paths and enables overwriting critical files like the SQLite database. Exploitation requires prior compromise of the dedicated SecureDrop Server, which itself is hardened and only accessible via Tor hidden services. Despite the high attack complexity, the vulnerability is rated High severity due to its significant impact on confidentiality, integrity, and availability of decrypted source submissions. This issue is similar to CVE-2025-24888 but occurs through a different code path, and a more robust fix has been implemented in the replacement SecureDrop Inbox codebase. The issue has been fixed in version 0.17.5.
CVSS 7.5
CVE-2026-40490 WRITEUP MEDIUM
AsyncHttpClient leaks authorization credentials to untrusted domains on cross-origin redirects
The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. When redirect following is enabled (followRedirect(true)), versions of AsyncHttpClient prior to 3.0.9 and 2.14.5 forward Authorization and Proxy-Authorization headers along with Realm credentials to arbitrary redirect targets regardless of domain, scheme, or port changes. This leaks credentials on cross-domain redirects and HTTPS-to-HTTP downgrades. Additionally, even when stripAuthorizationOnRedirect is set to true, the Realm object containing plaintext credentials is still propagated to the redirect request, causing credential re-generation for Basic and Digest authentication schemes via NettyRequestFactory. An attacker who controls a redirect target (via open redirect, DNS rebinding, or MITM on HTTP) can capture Bearer tokens, Basic auth credentials, or any other Authorization header value. The fix in versions 3.0.9 and 2.14.5 automatically strips Authorization and Proxy-Authorization headers and clears Realm credentials whenever a redirect crosses origin boundaries (different scheme, host, or port) or downgrades from HTTPS to HTTP. For users unable to upgrade, set `(stripAuthorizationOnRedirect(true))` in the client config and avoid using Realm-based authentication with redirect following enabled. Note that `(stripAuthorizationOnRedirect(true))` alone is insufficient on versions prior to 3.0.9 and 2.14.5 because the Realm bypass still re-generates credentials. Alternatively, disable redirect following (`followRedirect(false)`) and handle redirects manually with origin validation.

CVE-2026-41242 WRITEUP CRITICAL
protobufjs has an arbitrary code execution issue
protobufjs compiles protobuf definitions into JavaScript (JS) functions. In versions prior to 8.0.1 and 7.5.5, attackers can inject arbitrary code in the "type" fields of protobuf definitions, which will then execute during object decoding using that definition. Versions 8.0.1 and 7.5.5 patch the issue.
CVSS 9.8
CVE-2026-41282 WRITEUP MEDIUM
ProjectDiscovery Nuclei <3.8.0 - DSL Injection
ProjectDiscovery Nuclei 3 before 3.8.0 allows DSL expression injection. This affects use of -env-vars for multi-step templates against untrusted targets (not the default configuration).

CVE-2026-24467 WRITEUP CRITICAL
OpenAEV's Improper Password Reset Token Management Leads to Unauthenticated Account Takeover and Platform Compromise
OpenAEV is an open source platform allowing organizations to plan, schedule and conduct cyber adversary simulation campaign and tests. Starting in version 1.0.0 and prior to version 2.0.13, OpenAEV's password reset implementation contains multiple security weaknesses that together allow reliable account takeover. The primary issue is that password reset tokens do not expire. Once a token is generated, it remains valid indefinitely, even if significant time has passed or if newer tokens are issued for the same account. This allows an attacker to accumulate valid password reset tokens over time and reuse them at any point in the future to reset a victim’s password. A secondary weakness is that password reset tokens are only 8 digits long. While an 8-digit numeric token provides 100,000,000 possible combinations (which is secure enough), the ability to generate large numbers of valid tokens drastically reduces the required number of attempts to guess a valid password reset token. For example, if an attacker generates 2,000 valid tokens, the brute-force effort is reduced to approximately 50,000 attempts, which is a trivially achievable number of requests for an automated attack. (100 requests per second can mathematically find a valid password reset token in 500 seconds.) By combining these flaws, an attacker can mass-generate valid password reset tokens and then brute-force them efficiently until a match is found, allowing the attacker to reset the victim’s password to a value of their choosing. The original password is not required, and the attack can be performed entirely without authentication. This vulnerability enables full account takeover that leads to platform compromise. An unauthenticated remote attacker can reset the password of any registered user account and gain complete access without authentication. Because user email addresses are exposed to other users by design, a single guessed or observed email address is sufficient to compromise even administrator accounts with non-guessable email addresses. This design flaw results in a reliable and scalable account takeover vulnerability that affects any registered user account in the system. Note: The vulnerability does not require OpenAEV to have the email service configured. The exploit does not depend on the target email address to be a real email address. It just needs to be registered to OpenAEV. Successful exploitation allows an unauthenticated remote attacker to access sensitive data (such as the Findings section of a simulation), modify payloads executed by deployed agents to compromise all hosts where agents are installed (therefore the Scope is changed). Users should upgrade to version 2.0.13 to receive a fix.

CVE-2026-24468 WRITEUP MEDIUM
OpenAEV Vulnerable to Username/Email Enumeration Through Differential HTTP Responses in Password Reset API
OpenAEV is an open source platform allowing organizations to plan, schedule and conduct cyber adversary simulation campaign and tests. Starting in version 1.11.0 and prior to version 2.0.13, the /api/reset endpoint behaves differently depending on whether the supplied username exists in the system. When a non-existent email is provided in the login parameter, the endpoint returns an HTTP 400 response (Bad Request). When a valid email is supplied, the endpoint responds with HTTP 200. This difference in server responses creates an observable discrepancy that allows an attacker to reliably determine which emails are registered in the application. By automating requests with a list of possible email addresses, an attacker can quickly build a list of valid accounts without any authentication. The endpoint should return a consistent response regardless of whether the username exists in order to prevent account enumeration. Version 2.0.13 fixes this issue.
CVSS 5.3
CVE-2026-41389 WRITEUP MEDIUM
OpenClaw 2026.4.7 < 2026.4.15 - Arbitrary File Read via Unvalidated Tool-Result Media Paths
OpenClaw versions 2026.4.7 before 2026.4.15 fail to enforce local-root containment on tool-result media paths, allowing arbitrary local and UNC file access. Attackers can craft malicious tool-result media references to trigger host-side file reads or Windows network path access, potentially disclosing sensitive files or exposing credentials.
