Versions prior to 0.35.0 are subject to a Denial of Service. Users that have permissions to change Flux’s objects, either through a Flux source or directly within a cluster, can provide invalid data to fields `.spec.interval` or `.spec.timeout` (and structured variations of these fields), causing the entire object type to stop being processed. This issue is patched in version 0.35.0. As a workaround, Admission controllers can be employed to restrict the values that can be used for fields `.spec.interval` and `.spec.timeout`, however upgrading to the latest versions is still the recommended mitigation." } ] }, "impact": { "cvss": { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "LOW", "baseScore": 5.0, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "CHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:L", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-1284: Improper Validation of Specified Quantity in Input" } ] } ] }, "references": { "reference_data": [ { "name": "https://github.com/fluxcd/flux2/security/advisories/GHSA-f4p5-x4vc-mh4v", "refsource": "CONFIRM", "url": "https://github.com/fluxcd/flux2/security/advisories/GHSA-f4p5-x4vc-mh4v" }, { "name": "https://github.com/kubernetes/apimachinery/issues/131", "refsource": "MISC", "url": "https://github.com/kubernetes/apimachinery/issues/131" } ] }, "source": { "advisory": "GHSA-f4p5-x4vc-mh4v", "discovery": "UNKNOWN" } }
