Rank Math SEO: A security weakness
A user permitted to manage redirections, normally an Administrator, can save a malicious source value that is rendered unescaped in the redirection list. A more privileged viewer, including a multisite Super Administrator, can execute the stored script. The export does not name the endpoint or render function. Affected versions: < 1.0.280. The authoritative export identifies 1.0.280 as fixed for this CVE.

This CVE was published Oct 10, 2026 and is one of 4 known issues for this plugin.
Update, patch or deactivate.
Update to 1.0.280 or a later supported release. Application-level remediation: Validate redirection sources and escape them in the administrative list, including when displayed to network administrators.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The Rank Math SEO WordPress plugin before 1.0.280 does not escape a stored redirection source value before outputting it in an administrative list view, allowing users who can manage redirections (Administrators by default) to store JavaScript that executes in the session of any user who later opens that view, including a Super Administrator on multisite.
