Lifecycle Timeline
4DescriptionCVE.org
Jirafeau normally prevents browser preview for text files due to the possibility that for example SVG and HTML documents could be exploited for cross site scripting. This was done by storing the MIME type of a file and allowing only browser preview for MIME types beginning with image (except for image/svg+xml, see CVE-2022-30110 and CVE-2024-12326), video and audio. However, it was possible to bypass this check by sending a manipulated MIME type containing a comma and an other MIME type like text/html (for example image/png,text/html). Browsers see multiple MIME types and text/html would takes precedence, allowing a possible attacker to do a cross-site scripting attack. The check for MIME types was enhanced to prevent a browser preview when the stored MIME type contains a comma.

Technical ContextAI
Cross-site scripting (XSS) allows injection of client-side scripts into web pages viewed by other users due to insufficient output encoding.
RemediationAI
A vendor patch is available — apply it immediately. Encode all user-supplied output contextually (HTML, JS, URL). Implement Content Security Policy (CSP) headers. Use HTTPOnly and Secure cookie flags.
