Source agreement

Tam uyum

Evidence confidence

Short explanation

A path traversal vulnerability was identified in UbiquitousLearning mllm up to version 2.0.2 within the load_model function of the Convertor component. Manipulation of the shard_file argument leads to path traversal, requiring local access with an available public exploit.

Why does it matter?

This vulnerability allows local attackers to interact with vulnerable components, presenting low confidentiality, integrity, and availability impacts. The patch status remains unconfirmed as the project has not responded to early issue reports.

What should be done?

Follow vendor advisories and monitor for updates.
Restrict local access to the affected component.
