The K2 article gallery upload path accepts a zip/tar archive, extracts it under `/media/k2/galleries/<id>/`, and only renames image files (gif/jpg/jpeg/png/webp) to safe names — non-image files (including `.php`) are extracted as-is and remain executable via direct HTTP access.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
