Technical Analysis
The GutenKit WordPress plugin prior to version 2.5.0 does not properly sanitize SVG files uploaded through all enabled upload paths. This flaw enables users with file upload permissions to upload crafted SVG files containing malicious scripts. When these files are accessed by other users, including administrators, the embedded scripts execute, resulting in a stored Cross-Site Scripting (CWE-79) vulnerability.
Potential Impact
An attacker with file upload privileges can upload malicious SVG files that execute arbitrary scripts in the context of users viewing the files, potentially leading to session hijacking, privilege escalation, or other malicious actions against affected users, including administrators.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict file upload permissions to trusted users only and consider disabling SVG uploads if possible.
