Vulnerability description
DayBreach CVE AI Research
CVE-2026-109219 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
The Mang Board plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.4.4 via the mbw_file_upload function. This is due to missing file extension validation on the attacker-supplied image_path parameter, whose basename-derived file name bypasses the extension allowlist applied only to the separate file_name parameter. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. Exploitation requires the board to be configured to allow guest posts, which is the plugin's default mode; the required nonce is printed on every public board page, making it readable by any unauthenticated visitor without a WordPress login.
