When using lockFileMaintenance using the bazel-module or bazelisk managers between Renovate 43.65.0 (2026-03-12) and 43.102.11 (2026-04-02), there was the opportunity for remote code execution from a malicious dependency, if the Bazel module executes code that relies on a dependency .

As this is an "unsafe" execution path, we have disabled this by default, and self-hosted administrators must add it to the allowedUnsafeExecutions allowlist.

It is recommended to review whether you have enabled this functionality for these managers, and if so, whether any dependency updates may have led to remote code execution.

If Renovate suggested an update to a malicious dependency, and that dependency is referenced as part of the bazel mod deps call - for instance as part of a ctx.execute call - this would call attacker-controlled code.

This could lead to insider attackers and outside attackers, executing code that is distributed as part of the package.

This is patched in 43.102.11.

This does not affect any versions of Mend Renovate Self-Hosted.

This was missed in code review (as part of https://github.com/renovatebot/renovate/pull/41507).
