AI Analysis
Technical Summary
CVE-2026-11591 is a stored cross-site scripting vulnerability in the Widgets for Google Reviews WordPress plugin. It affects all versions up to and including 13.3. The vulnerability is due to improper neutralization of input during web page generation, allowing authenticated users with editor or higher privileges to inject arbitrary scripts via admin settings. This vulnerability is limited to multi-site WordPress installations or those with unfiltered_html disabled, enabling script execution when the injected pages are accessed.
Potential Impact
An authenticated attacker with editor-level or higher permissions can inject malicious scripts into pages via the plugin's admin settings. These scripts execute in the context of users visiting the affected pages, potentially leading to session hijacking, defacement, or other attacks that leverage the victim's browser privileges. The impact is limited by the requirement for elevated privileges and specific WordPress configurations (multi-site or unfiltered_html disabled).
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, restrict editor-level permissions to trusted users and consider enabling unfiltered_html capability if feasible. Monitor vendor channels for official fixes or updates addressing this vulnerability.
