{"id":"CVE-2024-31216","aliases":["GHSA-v554-xwgw-hc3w","GO-2024-2859"],"url":"https://o3.security/vulnerability/CVE-2024-31216","summary":"source-controller leaks theAzure Storage SAS token into logs on connection errors","details":"The source-controller is a Kubernetes operator, specialised in artifacts acquisition from external sources such as Git, OCI, Helm repositories and S3-compatible buckets. The source-controller implements the source.toolkit.fluxcd.io API and is a core component of the GitOps toolkit. Prior to version 1.2.5, when source-controller was configured to use an Azure SAS token when connecting to Azure Blob Storage, the token was logged along with the Azure URL when the controller encountered a connection error. An attacker with access to the source-controller logs could use the token to gain access to the Azure Blob Storage until the token expires. This vulnerability was fixed in source-controller v1.2.5. There is no workaround for this vulnerability except for using a different auth mechanism such as Azure Workload Identity.","published":"2024-05-15T15:52:15.084Z","modified":"2026-07-15T01:49:02.598809359Z","cvss":{"score":5.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/fluxcd/source-controller","fixedVersion":"1.2.5"}],"fix":{"url":"https://github.com/fluxcd/source-controller/commit/915d1a072a4f37dd460ba33079dc094aa6e72fa9","label":"fluxcd/source-controller@915d1a0"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/31xxx/CVE-2024-31216.json"},{"type":"ADVISORY","url":"https://github.com/fluxcd/source-controller/security/advisories/GHSA-v554-xwgw-hc3w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-31216"},{"type":"FIX","url":"https://github.com/fluxcd/source-controller/commit/915d1a072a4f37dd460ba33079dc094aa6e72fa9"},{"type":"FIX","url":"https://github.com/fluxcd/source-controller/pull/1430"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:02.598809359Z"}}
