CVE-2026-78075
On Joomla 3 builds where physical file deletion was triggered, an author could supply their own article ID alongside an arbitrary file path under the `/images/` directory to delete arbitrary files.
Does this matter?
Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.
