Changes

⚠️ Security Fixes

• GHSA-wjxp-xrpv-xpff / CVE-2026-40161 (HIGH): Git resolver API mode leaks system-configured API token to user-controlled serverURL. A user who can create TaskRuns can exfiltrate the system Git API token by pointing the resolver at an attacker-controlled server.

• GHSA-94jr-7pqp-xhcq / CVE-2026-40938 (HIGH): Git resolver unsanitized revision parameter enables argument injection. A malicious revision value can inject arbitrary flags into the git CLI, potentially leading to remote code execution on the resolver pod.

• GHSA-rx35-6rhx-7858 / CVE-2026-40923 (Medium): VolumeMount path restriction bypass via missing filepath normalization. Paths like /tekton/../sensitive bypass the /tekton/ prefix restriction check.

• GHSA-rmx9-2pp3-xhcr / CVE-2026-25542 (Medium): VerificationPolicy regex pattern bypass via substring matching. Unanchored patterns allow partial matches, letting unsigned resources pass verification.

• GHSA-m2cx-gpqf-qf74 / CVE-2026-40924 (Medium): HTTP resolver unbounded response body read enables OOM denial of service. A malicious URL returning a very large response can exhaust the resolver pod's memory. Response body is now limited to 1 MiB.
