## What is CVE-2026-19093?

CVE-2026-19093 is a medium-severity path traversal vulnerability in Unknown Tutor LMS, published on 22 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

The Tutor LMS  WordPress plugin before 4.0.6 does not validate a stored file path before using it to stream media, allowing users with the instructor role to read arbitrary files on the server, including files outside the web root.

The readable files include the WordPress configuration file, which exposes the database credentials and the authentication keys and salts, so authentication cookies can be forged.

Weakness: CWE-552 (Files or Directories Accessible to External Parties)
