CVE-2026-54752Network attack vector

Remote code execution via pull-request-controlled pickle deserialization

Published Sep 17, 2026 · Updated Sep 17, 2026

Deserialization of untrusted data in NetBox Device Type Library allows remote attackers to execute arbitrary code through a malicious pull request. The read_pickle_data function in tests/pickle_operations.py passes pull-request-controlled known-modules.pickle or known-racks.pickle content to pickle.load, invoking attacker-defined object reduction behavior. Execution requires GitHub Actions or a maintainer to run pytest after USE_LOCAL_KNOWN_SLUGS is enabled, exposing resources reachable from that runner or process.
