Detailsinfo

A vulnerability, which was classified as critical, was found in oobabooga text-generation-webui up to 4.1.0. Affected is some unknown processing of the file download-model.py of the component Setting Handler. The manipulation with an unknown input leads to a path traversal vulnerability.
