CVE-2026-71518
Typemill < 2.26.0 Authorization Bypass via Media File Download Route
Description

Typemill before 2.26.0 contains an authorization bypass vulnerability in the media file download route that allows unauthenticated attackers to access restricted files by submitting path-equivalent URL variants. Attackers can substitute normalized path forms such as dot-slash prefixes, double slashes, or percent-encoded sequences to pass role-based restriction checks while the filesystem resolves the request to the protected file, enabling unauthorized file download without credentials.
