CVE-2026-31223
HighSummary
The snorkel library thru v0.10.0 contains a critical insecure deserialization vulnerability in the BaseLabeler.load() method. This method loads serialized labeler models using the unsafe pickle.load() function on user-supplied file paths without any validation.
Risk Assessment
A remote attacker can exploit this vulnerability by providing a maliciously crafted pickle file, leading to arbitrary code execution on the victim's system. This poses a serious security risk for systems using this library.
Recommendation
It is recommended to update the snorkel library to the latest version that fixes this vulnerability. Additionally, avoid deserializing data from untrusted sources.

Original NVD description (English source)
The snorkel library thru v0.10.0 contains a critical insecure deserialization vulnerability (CWE-502) in the BaseLabeler.load() method of the BaseLabeler class. The method loads serialized labeler models using the unsafe pickle.load() function on user-supplied file paths without any validation or security controls. Python's pickle module is inherently dangerous for deserializing untrusted data, as it can execute arbitrary code during the deserialization process. A remote attacker can exploit this by providing a maliciously crafted pickle file, leading to arbitrary code execution on the victim's system when the file is loaded via the vulnerable method.
