CVE-2026-53872

Picklescan before 0.0.29 fails to detect malicious pickle files, allowing attackers to embed undetected code in these files. This code can execute arbitrary commands when loaded by victims.

Picklescan before 0.0.28 fails to detect malicious torch.jit.unsupported_tensor_ops.execWrapper function calls embedded in pickle files. Attackers can craft malicious pickle files that bypass picklescan detection and execute arbitrary code when loaded via pickle.load().

Picklescan before 0.0.33 fails to detect malicious pickle files that invoke numpy.f2py.crackfortran.myeval function through the reduce method. Attackers can craft malicious pickle files embedding arbitrary code that evades picklescan detection and executes remote code when loaded.

Picklescan before 0.0.29 fails to detect the profile.Profile.runctx function when analyzing pickle files, allowing attackers to embed undetected malicious code. Remote attackers can craft malicious pickle files using profile.Profile.runctx in the reduce method to achieve remote code execution when the pickle file is loaded.

Picklescan before version 1.0.3 contains a scanning bypass vulnerability in the scan_pytorch function. By using dynamic eval and the __reduce__ trick, attackers can embed malicious magic numbers in PyTorch payloads that evade picklescan detection.

Picklescan before 1.0.4 fails to block at least seven Python standard library modules, allowing for remote code execution. Attackers can craft malicious pickle files importing these unblocked modules, bypassing picklescan's safety validation.

Picklescan before 1.0.1 contains an unsafe deserialization vulnerability allowing unauthenticated users to execute arbitrary code by hiding eval calls nested under callable objects via getattr. Attackers can embed malicious code in pickle files that evades detection but executes when the pickle is loaded from untrusted sources.

Picklescan before 1.0.4 contains an incomplete blocklist for the profile module, allowing attackers to achieve arbitrary code execution via exec(). Attackers can craft malicious pickle files calling profile.run(statement) to execute arbitrary Python code.

Picklescan versions before 1.0.4 fail to block pkgutil.resolve_name, allowing attackers to bypass the entire blocklist through indirect REDUCE calls. Attackers can invoke any blocked function, leading to remote code execution.

Picklescan before version 0.0.27 contains a parsing logic error in the _list_globals function when handling STACK_GLOBAL opcodes. This error allows malicious pickle files to bypass detection, potentially leading to unexpected exceptions.
