{"id":"GHSA-v554-xwgw-hc3w","summary":"source-controller leaks Azure Storage SAS token into logs","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","aliases":["CVE-2024-31216","GO-2024-2859"],"modified":"2026-07-17T21:09:19.782699037Z","published":"2024-05-15T17:09:24Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2024-05-15T17:09:24Z","nvd_published_at":"2024-05-15T16:15:10Z","cwe_ids":["CWE-532"]},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/fluxcd/source-controller/pull/1430"},{"type":"WEB","url":"https://github.com/fluxcd/source-controller/commit/915d1a072a4f37dd460ba33079dc094aa6e72fa9"},{"type":"PACKAGE","url":"https://github.com/fluxcd/source-controller"}],"affected":[{"package":{"name":"github.com/fluxcd/source-controller","ecosystem":"Go","purl":"pkg:golang/github.com/fluxcd/source-controller"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.2.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/05/GHSA-v554-xwgw-hc3w/GHSA-v554-xwgw-hc3w.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
