A route that refreshes the credentials of a browser-extension channel signed data taken from the request itself and stored the result where the requesting user can read it back. A user could therefore obtain a validly signed token containing any claims they choose, which the application accepts as a session, as an organization invitation with a chosen role, as a password reset or as an enterprise provisioning token.\n\nA second, narrower route that creates team invitations signs extra fields from the request body in the same way.","published":"2026-10-24T15:17:34.000Z","lastModified":"2026-10-26T16:54:35.000Z","status":"Deferred","sourceIdentifier":"4cdc9741-f887-419a-a2fd-acbbd2729276","cvss":{"version":"3.1","score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"cwe":["CWE-290","CWE-345","CWE-915"],"affected":[],"epss":{"score":0.00249,"percentile":0.16176,"date":"2026-10-27","history":[{"date":"2026-10-25","score":0.00249,"percentile":0.16105}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.25%).
