CVE-2026-33022

MEDIUMPre-NVD 6.56.5
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 70% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

Tekton Pipelines project provides k8s-style resources for declaring CI/CD-style pipelines. 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.
