Unauthenticated Broken Access Control in User Registration <= 5.2.2 versions.

Mattermost versions 10.11.x <= 10.11.18, 11.6.x <= 11.6.3, 11.5.x <= 11.5.6 fail to validate attachment URLs against internal or private IP ranges in the Mattermost Agents plugin MCP server which allows an attacker with access to the MCP server in stdio mode to perform server-side request forgery (SSRF) and exfiltrate data from internal network services via supplying internal URLs as file attachments in post creation requests.. Mattermost Advisory ID: MMSA-2026-00635

When used to deliver a signal to a specific thread, thr_kill2(2) called p_cansignal() to determine whether the operation was permitted but did not check the result before delivering the signal. The signal was sent even when the permission check failed. The system call returned the resulting error to the caller, but by then the signal had already been delivered. The missing check allows an unprivileged local user who knows or can guess a target's process and thread IDs to send any signal to a process they would not normally be permitted to signal, including processes owned by other users or by root. The same check enforces jail boundaries, so a jailed process can signal processes on the host or in other jails. Thread IDs are allocated globally and sequentially, and so can be discovered by brute force with no visibility into the target. An attacker can stop or terminate arbitrary processes, including critical system daemons, resulting in a Denial of Service (DoS).

A heap overflow in the FSViewer.exe process of FastStone Image Viewer v8.3 allows attackers to cause a execute arbitrary code in the context of the current process via supplying a crafted JPEG 2000 (JP2) file.

Unauthenticated Content Injection in Auros Core <= 5.3.1 versions.

Unauthenticated Broken Access Control in Donation Thermometer <= 2.2.7 versions.

Contributor Broken Access Control in Live Copy Paste for Elementor <= 1.5.3 versions.

Subscriber Broken Access Control in Restaurant Menu by MotoPress <= 2.4.11 versions.

In JetBrains YouTrack before 2026.2.16593 improper access control allowed reading saved queries and tags

In JetBrains YouTrack before 2026.2.16593 default role configuration exposed excessive user profile details

In JetBrains YouTrack before 2026.2.16593 improper authorisation in the app configurations endpoint allowed modifying project settings

In JetBrains YouTrack before 2026.2.16593 improper access control allowed reading users' private data via the comment templates endpoint

In JetBrains Kotlin before 2.4.20 code execution was possible via unsafe deserialization in the build cache metadata

The Mattermost Go module github.com/mattermost/mattermost/server/public versions < v0.1.22 fail to validate path parameters when constructing API route paths which allows an attacker to redirect API calls to unintended endpoints via crafted IDs containing path traversal components. Mattermost Advisory ID: MMSA-2025-00532

By sending a deeply nested ASN1 structure to a Apache Kerby client or service, it's possible to trigger a StackOverFlow Exception which can lead to denial of service issues. Users are recommended to upgrade to version 2.1.2, which fixes this issue.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Tim Strifler Exclusive Addons Elementor allows Stored XSS. This issue affects Exclusive Addons Elementor: from n/a through 2.7.9.8.

A vulnerability in jupyter/nbconvert versions <= 7.17.0 allows for Cross-site Scripting (XSS) via unsanitized `text/vnd.mermaid` output in HTML exports. The `data_mermaid` block in `share/templates/lab/base.html.j2` renders `text/vnd.mermaid` cell output directly into HTML without escaping, enabling attackers to inject arbitrary HTML/JavaScript by breaking out of the `<pre>` tag. This vulnerability impacts any server using nbconvert to render notebooks as HTML, allowing attackers to execute arbitrary JavaScript in the context of users viewing the HTML export.

The User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder plugin for WordPress is vulnerable to unauthorized modification of data due to missing validation checks in the confirm_payment() function in all versions up to, and including, 5.2.0. This makes it possible for unauthenticated attackers to bypass payment processing and activate paid memberships.

The Frontend File Manager Plugin WordPress plugin through 23.6 does not properly verify ownership of every targeted post before permanent deletion, allowing authenticated users with author-level access and above to permanently delete arbitrary posts and pages. When the Frontend File Manager Plugin WordPress plugin through 23.6's "Allow guest uploads" setting is enabled by an administrator, the same deletion primitive becomes reachable by unauthenticated users.

The Printcart Web to Print Product Designer for WooCommerce WordPress plugin through 2.4.8 is vulnerable to path traversal which makes it possible for the attacker to retrieve the directory listing for arbitrary directories on the server.

Server-Side Request Forgery in the markdown_to_pdf action of Rapid7 InsightConnect Markdown Plugin on Linux in versions prior to 4.0.2 allows remote attackers to make arbitrary outbound HTTP requests via unsanitized resource-loading HTML elements (img/src, CSS url(), @import) embedded in Markdown input. The initial fix in 4.0.0 disabled JavaScript but did not neutralize resource-loading vectors. Resolved in 4.0.2 by sanitizing HTML with an allowlist of tags, attributes, and URL schemes.

A missing sanitisation vulnerability exists with user input in the stats-video.php script. The way URLs to this script were constructed did not follow best practices, and the output of the Smarty custom helper function url was neither properly encoded nor sanitised, allowing user‑supplied input to be reflected without escaping.

A bypass to the admin‑only restriction of the XML‑RPC API in Revive Adserver 6.0.7. The API response for the ox.login method returned a session ID cookie in the HTTP headers, and although the method correctly returned an error, the associated session was not invalidated. As a result, the leaked session ID could be used to perform subsequent API calls without restrictions.

A stored XSS vulnerabilities exists in the `maintenance-acl-check.php` and `maintenance-banners-check.php` tools of Revive Adserver 6.0.7. The issue was caused by entity names being displayed without proper escaping when inconsistencies were detected. Whether the XSS payload is executed when an administrator uses the affected maintenance tools is not entirely under the attacker's control.

A missing sanitisation vulnerability of user input in the zone-include.php script exists in Revive Adserver 6.0.7 and earlier. A low‑privileged user could exploit the refresh parameter of the iFrame invocation tag to perform reflected XSS attacks.
