ZDI Publishes 47 Meta AI Zero-Days
Zero Day Initiative published 47 CVSS 7.8 remote-code-execution advisories affecting Meta’s fairseq, fairseq2, FAIRChem, and Detectron2 after March reports remained unresolved. Crafted YAML, pickle, NPZ, or checkpoint files can execute attacker-controlled code when opened.
This is a major supply-chain warning for ML developers: model artifacts and configuration files are executable inputs when loaders trust unsafe serialization formats.
- –The disclosures span 47 advisories, all rated CVSS 7.8, across three major Meta-maintained AI libraries.
- –Exploitation generally requires opening a malicious file or visiting a malicious page, making shared research and training environments especially exposed.
- –Developers should treat checkpoints, configs, and datasets as untrusted; sandbox loaders and eliminate unsafe pickle/YAML deserialization paths.
- –The incident highlights the security cost of fragmented maintenance across popular open-source research frameworks.
