Detailsinfo

A vulnerability classified as problematic has been found in mmaitre314 picklescan up to 0.0.21. Affected is some unknown functionality of the component File Extension Handler. The manipulation with an unknown input leads to a reliance on untrusted inputs in a security decision vulnerability. CWE is classifying the issue as CWE-807. The product uses a protection mechanism that relies on the existence or values of an input, but the input can be modified by an untrusted actor in a way that bypasses the protection mechanism. This is going to have an impact on integrity. CVE summarizes:

picklescan before 0.0.22 only considers standard pickle file extensions in the scope for its vulnerability scan. An attacker could craft a malicious model that uses Pickle and include a malicious pickle file with a non-standard file extension. Because the malicious pickle file inclusion is not considered as part of the scope of picklescan, the file would pass security checks and appear to be safe, when it could instead prove to be problematic.
