CVE-2026-40938

The CVE concerns Tekton Pipelines’ git resolver (1.0.0–1.10.x) where the revision parameter is passed to git fetch as a positional argument without validating it does not start with a dash. An attacker can inject git fetch flags (e.g., --upload-pack=) because git treats mixed positional arguments...

Tekton Pipeline: Git Resolver Unsanitized Revision Parameter Enables git Argument Injection Leading to RCE

Summary The git resolver's revision parameter is passed directly as a positional argument to git fetch without any validation that it does not begin with a - character. Because git parses flags from mixed positional arguments, an attacker can inject arbitrary git fetch flags such as --upload-pack...
