CVE-2026-40161

HIGH

7.7

Description

Tekton Pipelines project provides k8s-style resources for declaring CI/CD-style pipelines. From 1.0.0 to 1.10.0, the Tekton Pipelines git resolver in API mode sends the system-configured Git API token to a user-controlled serverURL when the user omits the token parameter. A tenant with TaskRun or PipelineRun create permission can exfiltrate the shared API token (GitHub PAT, GitLab token, etc.) by pointing serverURL to an attacker-controlled endpoint.
