Vulnerability details
CVE-2026-83493
Distributed-workloads: github actions pinned by mutable tag/branch, including third-party snyk/actions/setup@master
CVSS 3.1
9.1Critical
Official description
A flaw was found in distributed-workloads. A remote attacker could exploit a vulnerability in the pull_request_target 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 SNYK_TOKEN, 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.
