Plexis Archiver is a collection of Plexus components to create archives or extract archives to a directory with a unified `Archiver`/`UnArchiver` API. Prior to version 4.8.0, using AbstractUnArchiver for extracting an archive might lead to an arbitrary file creation and possibly remote code execution. When extracting an archive with an entry that already exists in the destination directory as a symbolic link whose target does not exist - the `resolveFile()` function will return the symlink's source instead of its target, which will pass the verification that ensures the file will not be extracted outside of the destination directory. Later `Files.newOutputStream()`, that follows symlinks by default, will actually write the entry's content to the symlink's target. Whoever uses plexus archiver to extract an untrusted archive is vulnerable to an arbitrary file creation and possibly remote code execution. Version 4.8.0 contains a patch for this issue.

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.
