Credential disclosure via cached login form
Published Jun 12, 2026 · Updated Jun 12, 2026
Credential exposure in affected Redmine releases allows local users to recover submitted login credentials from a shared browser. The login and other sensitive form responses omit the Cache-Control no-store directive, allowing the browser cache to retain submitted username and password values after the request completes. Access to the same browser profile after the victim logs out is required, and the exposure is limited to credentials retained by that browser.
