LiteLLM 1.107.0 released with backdoor despite signed build

By PulseAugur Editorial · [1 sources] ·

The LiteLLM Python package experienced a security breach on October 21, 2026, when version 1.107.0 was released with a credential-stealing backdoor. Despite the release pipeline being cryptographically signed and previously hardened, an attacker exploited a three-hour window to inject malicious code. This involved compromising developer credentials, rewriting the build workflow, and uploading seven backdoored wheels to PyPI, followed by infected images on GHCR and Docker Hub. This marks the second documented hijacking of LiteLLM in 2026, raising concerns about the project's overall security record, which includes multiple critical CVEs. AI
