CVE-2026-9833
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk6th percentile - higher than 6% of all known CVEs
Summary
The Tag Groups WordPress plugin before version 2.2.0 improperly escapes one of its AJAX parameters before reflecting it in the response body served with an HTML content type. This allows unauthenticated attackers to execute arbitrary JavaScript in the browser of a logged-in user with `edit_pages` capability (Editor or higher) who is tricked into following a crafted link.
Risk Assessment
The risk involves potential session hijacking or unauthorized actions within the context of an editor or administrator account, which could lead to data theft, content modification, or further propagation of the attack within the organization.
Recommendation
Immediately update the Tag Groups plugin to version 2.2.0 or later. Additionally, train users with editor-level permissions to avoid clicking on suspicious links.
