Kuno Cms · Kuno Cms · CVE-2025-61681
**Name of the Vulnerable Software and Affected Versions**
KUNO CMS versions prior to 1.3.14
**Description**
KUNO CMS, a full-stack blog application, has flaws in its file upload functionality. The upload process only validates file types based on Content-Type headers and does not analyze file content or enforce extension whitelists. This allows attackers to upload SVG files containing malicious scripts, disguised as images. When users access the pages displaying these uploaded resources, arbitrary JavaScript executes in their browsers. The affected API endpoint is the file upload functionality. The vulnerable parameter is the file itself.
**Recommendations**
Update KUNO CMS to version 1.3.14 or later.
