Name of the Vulnerable Software and Affected Versions DeepDiff versions 5.0.0 through 8.6.0 Description DeepDiff is a Python project for deep difference and search of data. Versions 5.0.0 through 8.6.0 are susceptible to class pollution through the Delta class constructor. When combined with a...

The Art of Hide and Seek: Making Pickle-Based Model Supply Chain Poisoning Stealthy Again

Pickle deserialization vulnerabilities have persisted throughout Python's history, remaining widely recognized yet unresolved. Due to its ability to transparently save and restore complex objects into byte streams, many AI/ML frameworks continue to adopt pickle as the model serialization protocol...
