CVE-2026-34926MEDIUM 6.7

A directory traversal vulnerability in the Apex One (on-premise) server could allow a pre-authenticated local attacker to modify a key table on the server to inject malicious code to deploy to agents on affected installations. This vulnerability is only exploitable on the on-premise version of Apex One and a potential attacker must have access to the Apex One Server and already obtained administrative credentials to the server via some other method to exploit this vulnerability.

CVE-2026-7594HIGH 7.3

A vulnerability was detected in Flux159 mcp-game-asset-gen 0.1.0. Affected is the function image_to_3d_async of the file src/index.ts of the component MCP Interface. The manipulation of the argument statusFile results in path traversal. The attack can be executed remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

CVE-2026-1056CRITICAL 9.8

The Snow Monkey Forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'generate_user_dirpath' function in all versions up to, and including, 12.0.3. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

CVE-2026-22249HIGH 7.1

Docmost is an open-source collaborative wiki and documentation software. From 0.21.0 to before 0.24.0, Docmost is vulnerable to Arbitrary File Write via Zip Import Feature (ZipSlip). In apps/server/src/integrations/import/utils/file.utils.ts, there are no validation on filename. This vulnerability is fixed in 0.24.0.

CVE-2025-14301CRITICAL 9.8

The Integration Opvius AI for WooCommerce plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.3.0. This is due to the `process_table_bulk_actions()` function processing user-supplied file paths without authentication checks, nonce verification, or path validation. This makes it possible for unauthenticated attackers to delete or download arbitrary files on the server via the `wsaw-log[]` POST parameter, which can be leveraged to delete critical files like `wp-config.php` or read sensitive configuration files.
