Summary
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.
Risk Assessment
The risk includes unauthorized access to confidential files, which could lead to data disclosure, confidentiality breaches, and potential further attacks.
Recommendation
It is recommended to immediately upgrade Typemill to version 2.26.0 or later, which contains the fix.
Other vulnerabilities in Typemill
See all- CVE-2026-71213Critical
Typemill's login endpoint (POST /tm/login, ControllerWebAuth::login) performs no rate-limiting, failed-attempt counting, or account lockout when captcha is disabled, which is the default configuration. An unauthenticated attacker can send unlimited password-guessing requests against any account, including administrators, with no throttling.
- CVE-2026-53468Medium
Typemill is a flat-file, Markdown-based content management system designed for informational documentation websites. Versions prior to 2.23.0 are vulnerable to stored HTML attribute injection in the page metadata fields (`og:title` and `og:description`). An authenticated user with permission to modify page metadata can inject arbitrary HTML attributes into generated `<meta>` tags due to missing output encoding. Under certain browser or DOM interaction scenarios, this may lead to stored cross-site scripting (XSS). Version 2.23.0 fixes the issue.
- CVE-2026-49133Medium
Typemill before version 2.24.0 contains a path traversal vulnerability that allows authenticated attackers with Author-level privileges to read arbitrary files outside the content directory by supplying traversal sequences in the path query parameter passed to Storage::getFile() with an empty folder argument. Attackers can bypass traversal-prevention controls in Storage::getFolderPath() to access sensitive files.
