{"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":"### Impact\n\nWhen source-controller is configured to use an [Azure SAS token](https://v2-2.docs.fluxcd.io/flux/components/source/buckets/#azure-blob-sas-token-example) 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.\n\n### Patches\n\nThis vulnerability was fixed in source-controller **v1.2.5**.\n\n### Workarounds\n\nThere is no workaround for this vulnerability except for using a different auth mechanism such as [Azure Workload Identity](https://v2-2.docs.fluxcd.io/flux/components/source/buckets/#azure). \n\n### Credits\n\nThis issue was reported and fixed by Jagpreet Singh Tamber (@jagpreetstamber) from the Azure Arc team.\n\n### References\n\nhttps://github.com/fluxcd/source-controller/pull/1430\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n- Open an issue in the source-controller repository.\n- Contact us at the CNCF Flux Channel.\n","published":"2024-05-15T15:52:15.084Z","modified":"2026-08-12T03:51:26.240624803Z","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":{"score":0.00213,"percentile":0.1184,"asOf":"2026-08-23"},"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"},{"type":"PACKAGE","url":"https://github.com/fluxcd/source-controller"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:26.240624803Z"}}
