What is CVE-2025-50461?
A deserialization vulnerability is present in Volcengine's verl 3.0.0, particularly in the model merger script. This flaw arises when the script processes user-supplied .pt files without proper validation while invoking torch.load() with weights_only set to False. An attacker could exploit this vulnerability by designing a malicious model file and persuading a victim to download and store it in a specific local directory. Upon execution, this may permit the attacker to execute arbitrary code with the same privileges as the user running the script.
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
