Description
Semantic MediaWiki from 2.5.0 before 7.3.1 contains an improper authorization vulnerability that allows ordinary editors to permanently protect pages by adding an Is edit protected annotation. When $smwgEditProtectionRight is enabled, EditProtectionUpdater applies indefinite edit and move restrictions without checking the author's rights, locking other editors and administrators out.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-116876 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
