Summary
UbiquitousLearning mllm up to 2.0.2 contains a path traversal flaw (CWE-22) in the load_model function of the Convertor component. The shard_file argument is not restricted to the intended directory, so a crafted path can reach files outside it. A local attacker can exploit this, and a public exploit is available and may be used.
