CVE-2026-40924

CVE-2026-40924 – Tekton Pipelines HTTP Resolver Unbounded Read Leads to DoS . The vulnerability affects Tekton Pipelines where, prior to 1.11.1, the HTTP resolver’s FetchHttpResource calls io.ReadAll on resp.Body with no size limit. A tenant with permission to create TaskRuns or PipelineRuns refe...

CVE-2026-40924 Tekton Pipelines: HTTP Resolver Unbounded Response Body Read Enables Denial of Service via Memory Exhaustion

Tekton Pipelines project provides k8s-style resources for declaring CI/CD-style pipelines. Starting in version 1.0.0 and prior to versions 1.0.2, 1.3.4, 1.6.2, 1.9.3, and 1.11.1, the HTTP resolver's FetchHttpResource function calls io.ReadAllresp.Body with no response body size limit. Any tenant...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the HTTP resolver process. An attacker can cause excessive memory consumption and termination of the tekton-pipelines-resolvers pod by directing it to retrieve a very large HT...

Starting in version 1.0.0 and prior to versions 1.0.2, 1.3.4, 1.6.2, 1.9.3, and 1.11.1, the git resolver's revision parameter is passed directly as a positional argument to git fetch without any validation...

CVE-2026-40938 Tekton Pipelines: Git Resolver Unsanitized Revision Parameter Enables git Argument Injection Leading to RCE

Tekton Pipelines project provides k8s-style resources for declaring CI/CD-style pipelines. Starting in version 1.0.0 and prior to versions 1.0.2, 1.3.4, 1.6.2, 1.9.3, and 1.11.1, the git resolver's revision parameter is passed directly as a positional argument to git fetch without any validation...

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...

GHSA-94JR-7PQP-XHCQ 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...

Tekton Pipelines: VolumeMount path restriction bypass via missing filepath.Clean in /tekton/ check

Summary A validation bypass in the VolumeMount path restriction allows mounting volumes under restricted /tekton/ internal paths by using .. path traversal components. The restriction check uses strings.HasPrefix without filepath.Clean, so a path like /tekton/home/../results passes validation but...
