CVE-2026-48945

Joomla Extension - getk2.com - Privileged RCE vulnerability in K2 extension for Joomla < 2.26

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.
