Concrete CMS before 9.5.4 re-authorized OAuth REST API requests from the bearer token alone and did not re-check the state of the account the token had been issued to. The resource server’s authorization validator confirmed only that a token existed, had not expired, and had not been explicitly revoked, and deactivating a user did not revoke that user’s outstanding tokens. As a result, a deactivated user retained full access to \/ccm\/api\/1.0\/* for the remaining lifetime of any token already issued to them. The same gap applied to accounts that had been deleted or locked pending a forced password reset.\u00a0The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 2.0 with vector CVSS:4.0\/AV:N\/AC:H\/AT:P\/PR:L\/UI:A\/VC:L\/VI:L\/VA:N\/SC:N\/SI:N\/SA:N.
