CVE-2026-126318: REDAXO before 5.21.6 Authorization Bypass of Live Version Permission
Noroxi assessment
Priority: Monitor (action score 21/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: redaxo core 5.21.6.
Low priority for now. Upgrade to redaxo core 5.21.6 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
REDAXO before 5.21.6 contains an authorization bypass vulnerability that allows editors without the version[live_version] permission to modify live article versions by bypassing working version enforcement. Authenticated editors can add, edit, delete, toggle, or reorder live slices via content/functions, slice ids, content_slice_status, content_move_slice, history restore, or content_copy, bypassing approval workflows.
