Name of the Vulnerable Software and Affected Versions picklescan versions prior to 0.0.30
Description The software fails to detect malicious pickle files that exploit the make label() function within lib2to3.pgen2.pgen.ParserGenerator inside the reduce method. This allows attackers to craft pickle files containing embedded code that bypasses detection and executes arbitrary commands when the pickle.load() function is called.
