From 2.0.0 until 2.5.0, AuthRequired accepts a browser-managed token cookie as an API credential after the front end stores the JWT in that cookie. Because management endpoints do not universally require a CSRF token or perform Origin or Referer validation, a remote attacker can induce a logged-in administrator's browser to submit authenticated cross-site state-changing requests, including POST /api/configs. The attack requires an administrator account without OTP/Passkey or a target endpoint that does not require secure-session proof. The attacker cannot read the cross-origin response but can modify Nginx configuration, trigger reloads, or invoke other management operations reachable with the victim's session. This issue is fixed in version 2.5.0." } ], "source": { "advisory": "GHSA-33rr-wq23-g6gg", "discovery": "UNKNOWN" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-10-09T16:16:13.986272Z", "id": "CVE-2026-107809", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-10-09T16:45:22.243Z" } } ] } }
