NordVPN 6.19.6 contains a denial of service vulnerability that allows local attackers to crash the application by submitting an excessively long string in the email input field. Attackers can paste a buffer of 100,000 characters into the email field during login to trigger an application crash.

Pidgin 2.13.0 contains a denial of service vulnerability that allows local attackers to crash the application by providing an excessively long username string during account creation. Attackers can input a buffer of 1000 characters in the username field and trigger a crash when joining a chat, causing the application to become unavailable.

OpenClaw versions prior to 2026.2.25 fail to consistently apply sender-policy checks to reaction_* and pin_* non-message events before adding them to system-event context. Attackers can bypass configured DM policies and channel user allowlists to inject unauthorized reaction and pin events from restricted senders.

OpenClaw versions prior to 2026.2.25 contain a symlink traversal vulnerability in browser trace and download output path handling that allows local attackers to escape the managed temp root directory. An attacker with local access can create symlinks to route file writes outside the intended temp directory, enabling arbitrary file overwrite on the affected system.

The Canto plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.1.1 via the `/wp-content/plugins/canto/includes/lib/copy-media.php` file. This is due to the file being directly accessible without any authentication, authorization, or nonce checks, and the `fbc_flight_domain` and `fbc_app_api` URL components being accepted as user-supplied POST parameters rather than read from admin-configured options. Since the attacker controls both the destination server and the `fbc_app_token` value, the entire fetch-and-upload chain is attacker-controlled — the server never contacts Canto's legitimate API, and the uploaded file originates entirely from the attacker's infrastructure. This makes it possible for unauthenticated attackers to upload arbitrary files (constrained to WordPress-allowed MIME types) to the WordPress uploads directory. Additional endpoints (`detail.php`, `download.php`, `get.php`, `tree.php`) are also directly accessible without authentication and make requests using a user-supplied `app_api` parameter combined with an admin-configured subdomain.

The Survey plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

OpenClaw versions prior to 2026.2.25 contain an approval-integrity bypass vulnerability in system.run where rendered command text is used as approval identity while trimming argv token whitespace, but runtime execution uses raw argv. An attacker can craft a trailing-space executable token to execute a different binary than what the approver displayed, allowing unexpected command execution under the OpenClaw runtime user when they can influence command argv and reuse an approval context.

Claude Code is an agentic coding tool. Versions prior to 2.1.53 resolved the permission mode from settings files, including the repo-controlled .claude/settings.json, before determining whether to display the workspace trust confirmation dialog. A malicious repository could set permissions.defaultMode to bypassPermissions in its committed .claude/settings.json, causing the trust dialog to be silently skipped on first open. This allowed a user to be placed into a permissive mode without seeing the trust confirmation prompt, making it easier for an attacker-controlled repository to gain tool execution without explicit user consent. This issue has been patched in version 2.1.53.

Checkmate is an open-source, self-hosted tool designed to track and monitor server hardware, uptime, response times, and incidents in real-time with beautiful visualizations. In versions from 3.5.1 and prior, a mass assignment vulnerability in Checkmate's user profile update endpoint allows any authenticated user to escalate their privileges to superadmin, bypassing all role-based access controls. An attacker can modify their user role to gain complete administrative access to the application, including the ability to view all users, modify critical configurations, and access sensitive system data. At time of publication, there are no publicly available patches.

Discourse is an open-source discussion platform. Prior to versions 2026.3.0-latest.1, 2026.2.1, and 2026.1.2, unauthenticated users can determine whether a specific user is a member of a private group by observing changes in directory results when using the `exclude_groups` parameter. Versions 2026.3.0-latest.1, 2026.2.1, and 2026.1.2 contain a patch. As a workaround, disable public access to the user directory via Admin → Settings → hide user profiles from public.
