What is CVE-2026-24140?

CVE-2026-24140 is a low-severity vulnerability in franklioxygen MyTube, published on 23 Jan 2026. An attacker needs administrator access to exploit it, with no action from the victim.

Official description

MyTube is a self-hosted downloader and player for several video websites. Versions 1.7.78 and below have a Mass Assignment vulnerability in the settings management functionality due to insufficient input validation. The application's saveSettings() function accepts arbitrary key-value pairs without validating property names against allowed settings. The function uses Record<string, any> as input type and iterates over all entries using Object.entries() without filtering unauthorized properties. Any field sent by the attacker is directly persisted to the database, regardless of whether it corresponds to a legitimate application setting. This issue has been fixed in version 1.7.78.

Weakness: CWE-915
