Versions 0.60.0 through 1.0.0, 1.1.0 through 1.3.2, 1.4.0 through 1.6.0, 1.7.0 through 1.9.0, 1.10.0, and 1.10.1 have a denial-of-service vulnerability in that allows any user who can create a TaskRun or PipelineRun to crash the controller cluster-wide by setting .spec.taskRef.resolver (or .spec.pipelineRef.resolver) to a string of 31+ characters. The crash occurs because GenerateDeterministicNameFromSpec produces a name exceeding the 63-character DNS-1123 label limit, and its truncation logic panics on a [-1] slice bound since the generated name contains no spaces. Once crashed, the controller enters a CrashLoopBackOff on restart (as it re-reconciles the offending resource), blocking all CI/CD reconciliation until the resource is manually deleted. Built-in resolvers (git, cluster, bundles, hub) are unaffected due to their short names, but any custom resolver name triggers the bug. The fix truncates the resolver-name prefix instead of the full string, preserving the hash suffix for determinism and uniqueness. This issue has been patched in versions 1.0.1, 1.3.3, 1.6.1, 1.9.2 and 1.10.2."}],"source":{"advisory":"GHSA-cv4x-93xx-wgfj","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-20T16:22:10.536063Z","id":"CVE-2026-33022","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-20T18:07:35.331Z"}}]}}
