CVE-2026-83493: Distributed-workloads: github actions pinned by mutable tag/branch, including third-party snyk/actions/setup@master

A flaw was found in distributed-workloads. A remote attacker could exploit a vulnerability in the pullrequesttarget workflow by submitting a specially crafted pull request. This workflow processes untrusted code from the pull request author while operating with the base repository's sensitive secrets, such as the SNYKTOKEN, and its default write token. Consequently, an attacker could exfiltrate these secrets, leading to unauthorized access to the Snyk integration and potential control over the repository.
