Unauthenticated attackers on default installs can save filtertags markup in a page with a trailing-backslash token that breaks quote parity under MySQL backslash escaping. This lets them inject a five-column UNION subquery to read arbitrary table data such as password hashes.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":59,"depthScoreParts":{"impact":47.3,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":216601,"id":"CVE-2026-104457","ts":1791306672551,"field":"exploit_available","old":"false","new":"true"}]}
