{"id":"CVE-2026-122222","kind":"vulnerability","aliases":["CVE-2026-122222"],"related":[],"title":"WordPress Permalink Manager Lite: stored script injection via post slug","description":"The Permalink Manager Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'slug' parameter in all versions up to, and including, 2.6.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. An Author-level attacker can submit a percent-encoded HTML/JavaScript payload as a post slug via the REST API, which survives sanitization intact and executes in an administrator's browser session when the URI Editor admin page is loaded.","summary":"The Permalink Manager Lite WordPress plugin up to and including 2.6.1 does not sanitize the 'slug' parameter, so an author-level user can store a script in a post slug. The script runs in an administrator's browser when they load the URI Editor admin page, letting an attacker act with admin rights.","severity":"medium","cvss":6.4,"epss":null,"exploited":false,"exploited_at":null,"products":[],"ecosystems":[],"tags":["package","permalink-manager-lite","wordpress"],"not_affected_if":["no-author-accounts","plugin-not-installed"],"how_to_check":"- Check the installed version of the Permalink Manager Lite plugin in the WordPress admin plugin list; versions up to and including `2.6.1` are affected.\n- Review which users hold the Author role or above on the site.","fix":null,"status":"open","published_at":"2026-11-06T09:17:00+00:00","first_seen_at":"2026-11-06T09:40:32+00:00","triaged_at":"2026-11-06T09:40:42+00:00","updated_at":"2026-11-06T09:40:42+00:00","category":"package","confidence":0.7,"triage":{"at":"2026-11-06T09:40:42Z","model":"claude-haiku-5-5","output":{"fix":"unknown","reach":"network","title":"WordPress Permalink Manager Lite: stored script injection via post slug","impact":"medium","summary":"The Permalink Manager Lite WordPress plugin up to and including 2.6.1 does not sanitize the 'slug' parameter, so an author-level user can store a script in a post slug.
