→Look for authenticated POST requests to /ajax/kanban.php with a request body containing action=update, itemtype=User, and column_field=api_token — this pattern indicates an attempt to overwrite a target user's API token for account takeover.
→The attack is performed by any authenticated (logged-in) user regardless of profile, so the presence of a valid session cookie does not rule out malicious activity — focus on the Kanban AJAX endpoint abuse pattern. ↗
→Snort/Suricata SID 2067163 (ET rule) covers this exploit; deploy with TLS inspection (SSLDecrypt/TLSDecrypt) enabled for full coverage as the rule metadata flags tls_state TLSDecrypt.

·No workarounds exist; the only remediation is upgrading GLPI to version 10.0.10 or later. ↗
