CVSS 3.1
9.1 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:NCVE-2026-83493
Critical (9.1). EPSS 0.3% estimated probability of exploitation activity in the next 30 days.
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.

Red Hat
Red Hat rates this Moderate.
The vulnerability in a pull_request_target workflow within the red-hat-data-services/distributed-workloads repository allowed an attacker to exfiltrate the SNYK_TOKEN secret by submitting a malicious pull request. This Moderate impact flaw could have led to unauthorized access to the Snyk integration and potentially the repository's write token. This issue has been remediated by deleting the vulnerable workflow and removing the SNYK_TOKEN.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
