CVE-2026-75569 (GCVE-0-2026-75569)

Vulnerability from cvelistv5 – Published: 2026-08-19 20:47 – Updated: 2026-09-08 12:30

Title

Mce-operator-bundle: all github actions pinned by mutable tag, not commit sha

Summary

A flaw was found in mce-operator-bundle. The build process fetches and executes scripts from a remote repository without performing integrity checks, such as commit pinning or signature verification. This allows a malicious actor with write access to the remote repository to inject and execute arbitrary code during the build. The consequence is a compromised build process, potentially leading to the distribution of malicious software.

Severity

7.7 (High)

  "details": "A flaw was found in mce-operator-bundle. The build process fetches and executes scripts from a remote repository without performing integrity checks, such as commit pinning or signature verification. This allows a malicious actor with write access to the remote repository to inject and execute arbitrary code during the build. The consequence is a compromised build process, potentially leading to the distribution of malicious software.",
