{"id":"CVE-2023-22482","state":"PUBLISHED","title":"JWT audience claim is not verified","description":"Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Versions of Argo CD starting with v1.8.2 and prior to 2.3.13, 2.4.19, 2.5.6, and 2.6.0-rc-3  are vulnerable to an improper authorization bug causing the API to accept certain invalid tokens. OIDC providers include an `aud` (audience) claim in signed tokens. The value of that claim specifies the intended audience(s) of the token (i.e. the service or services which are meant to accept the token). Argo CD _does_ validate that the token was signed by Argo CD's configured OIDC provider. But Argo CD _does not_ validate the audience claim, so it will accept tokens that are not intended for Argo CD. If Argo CD's configured OIDC provider also serves other audiences (for example, a file storage service), then Argo CD will accept a token intended for one of those other audiences. Argo CD will grant the user privileges based on the token's `groups` claim, even though those groups were not intended to be used by Argo CD. This bug also increases the impact of a stolen token. If an attacker steals a valid token for a different audience, they can use it to access Argo CD. A patch for this vulnerability has been released in versions 2.6.0-rc3, 2.5.6, 2.4.19, and 2.3.13. There are no workarounds.","publishedAt":"2023-01-25T18:25:15.287Z","updatedAt":"2025-03-11T13:30:49.509Z","severity":{"score":9.1,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["argoproj argo-cd"],"affected":[{"vendor":"argoproj","product":"argo-cd","versions":[{"version":">= 1.8.2, < 2.3.13","status":"affected"},{"version":">= 2.4.0-rc1, < 2.4.19","status":"affected"},{"version":">= 2.5.0-rc1, < 2.5.6","status":"affected"},{"version":">= 2.6.0-rc1, < 2.6.0-rc3","status":"affected"}]}],"references":["https://github.com/argoproj/argo-cd/security/advisories/GHSA-q9hr-j4rf-8fjc"],"weaknesses":["CWE-863"],"ingestedAt":"2026-10-29T20:05:43.909Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/22xxx/CVE-2023-22482.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-22482","state":"PUBLISHED","datePublished":"2023-01-25T18:25:15.287Z","dateUpdated":"2025-03-11T13:30:49.509Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2022-12-29T17:41:28.088Z"},"containers":{"cna":{"title":"JWT audience claim is not verified","descriptions":[{"lang":"en","value":"Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes.
