What is CVE-2025-71378?

The vulnerability in Picklescan, prior to version 0.0.30, allows attackers to exploit the lack of detection of cProfile.runctx function calls within the reduce methods of pickle files. This oversight enables malicious pickle files to circumvent standard detection mechanisms, leading to the execution of arbitrary code when loaded via pickle.load(). This poses a significant risk, particularly in applications relying on the untrusted loading of pickle data.
