## What is MAL-2026-11091?

MAL-2026-11091 is a malicious package in txs-runner-lib, published on 27 Jul 2026. 

### Official description

Package txs-runner-lib@1.0.1 could not be fully characterized: automated tracing engaged with the package's files but its output was withheld by the provider safety filter, and no a static rule findings are available to corroborate specific behavior. Content-filter suppression on package internals is an atypical outcome for benign libraries and warrants human inspection of the tarball contents before use, but without specific traced code paths or matched patterns, no concrete installer-harm behavior (exfiltration endpoint, credential read, dropper, backdoor) can be named for this version.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

## What should I do about MAL-2026-11091?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
