Renovate 43.65.0 before 43.102.11 Remote Code Execution via lockFileMaintenance

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Renovate versions from 43.65.0 before 43.102.11 contain a remote code execution vulnerability in bazel-module and bazelisk managers when using lockFileMaintenance. Attackers can execute arbitrary code by providing malicious dependencies that are referenced in bazel mod deps calls, such as within ctx.execute statements.

When using [`lockFileMaintenance`](https://docs.renovatebot.com/configuration-options/#lockfilemaintenance) using the [bazel-module](https://docs.renovatebot.com/modules/manager/bazel-module/) or [bazelisk](https://docs.renovatebot.com/modules/manager/bazelisk/) managers between Renovate [43.65.0](https://github.com/renovatebot/renovate/releases/tag/43.65.0) (2026-03-12) and [43.102.11](https://github.com/renovatebot/renovate/releases/tag/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`](https://docs.renovatebot.com/self-hosted-configuration/#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. ## Impact 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](https://docs.renovatebot.com/security-and-permissions/#execution-of-code-insider-attack) and [outside attackers](https://docs.renovatebot.com/security-and-permissions/#execution-of-code-outsider-attack), executing code that is distributed as part of the package. ## Patches This is patched in [43.102.11](https://github.com/renovatebot/renovate/releases/tag/43.102.11). This does not affect any versions of [Mend Renovate Self-Hosted](https://www.mend.io/renovate/). ## Workarounds - Upgrade your Renovate version - Disable `lockFileMaintenance` for these managers ## Why did this happen? This was missed in code review (as part of https://github.com/renovatebot/renovate/pull/41507).
