Overview
deepdiff is a Deep Difference and Search of any Python object/data. Recreate objects by adding adding deltas to each other.
Affected versions of this package are vulnerable to Class Pollution via the Delta constructor and manipulation of the SAFE_TO_IMPORT set. An attacker can execute arbitrary code or cause application crashes by supplying crafted input that exploits class pollution and insecure deserialization.
Note:
This is exploitable if untrusted user input is passed directly to the Delta class.
