{"id":"CVE-2026-55435","aliases":["GHSA-wqxv-w64v-5wh6","GO-2026-5925"],"url":"https://o3.security/vulnerability/CVE-2026-55435","summary":"Suspended Coder users retain access to AI Bridge LLM proxy endpoints","details":"Coder allows organizations to provision remote development environments via Terraform. Starting in version 2.30.0 and prior to versions 2.32.7, 2.33.8, and 2.34.2, AI Bridge proxy endpoints authenticate via `Server.IsAuthorized` in `coderd/aibridgedserver`, which validates key format, expiry, secret and deleted or system users but does not check whether the account is suspended. Because suspension does not revoke existing API keys, a suspended user's unexpired token keeps working. Practical impact is limited to already-issued API keys of suspended users until those keys are deleted. Versions 2.32.7, 2.33.8, and 2.34.2 patch the issue. As a workaround, on suspension, delete the user's API keys via `DELETE /api/v2/users/{user}/keys`.","published":"2026-07-07T17:37:31.211Z","modified":"2026-08-12T03:51:43.323359778Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"},"epss":{"score":0.00315,"percentile":0.23422,"asOf":"2026-07-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/coder/coder/v2","fixedVersion":"2.34.2"},{"ecosystem":"Go","name":"github.com/coder/coder/v2","fixedVersion":"2.33.8"},{"ecosystem":"Go","name":"github.com/coder/coder/v2","fixedVersion":"2.32.7"}],"fix":{"url":"https://github.com/coder/coder/commit/0d2c9f904a8b75b888140fcc8fbf4633660cc787","label":"coder/coder@0d2c9f9"},"references":[{"type":"WEB","url":"https://github.com/coder/coder/releases/tag/v2.32.7"},{"type":"WEB","url":"https://github.com/coder/coder/releases/tag/v2.33.8"},{"type":"WEB","url":"https://github.com/coder/coder/releases/tag/v2.34.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55435.json"},{"type":"ADVISORY","url":"https://github.com/coder/coder/security/advisories/GHSA-wqxv-w64v-5wh6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55435"},{"type":"FIX","url":"https://github.com/coder/coder/commit/0d2c9f904a8b75b888140fcc8fbf4633660cc787"},{"type":"FIX","url":"https://github.com/coder/coder/pull/26164"},{"type":"FIX","url":"https://github.com/coder/coder/pull/26173"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:43.323359778Z"}}
