| Doc Text: |
A flaw was found in Tekton Pipelines. An attacker can bypass restrictions on where volumes can be mounted by using specially crafted paths that include directory traversal sequences (e.g., `..`). This vulnerability, stemming from an incomplete path validation check, could allow unauthorized access to internal system directories, potentially leading to information disclosure or limited modification of sensitive data.
