What is CVE-2026-19697?

The GutenKit WordPress plugin prior to version 2.5.0 is vulnerable due to inadequate sanitization of uploaded SVG files, particularly on various upload paths. This flaw allows users with file upload permissions, such as Authors, to upload malicious SVG files. Consequently, these files can initiate Stored Cross-Site Scripting attacks, potentially impacting any user who accesses them, including site administrators. This vulnerability underscores the importance of secure file handling practices within WordPress plugins.
