Exploitation Probability (EPSS)

Low risk

0.27%

19th percentile - higher than 19% of all known CVEs

Summary

In Open WebUI versions from 0.6.27 before 0.10.0, the get_all_models handlers in routers/openai.py and routers/ollama.py passed a lambda to the aiocache key instead of key_builder, causing permission-filtered per-user model lists to share a static cache entry. This exposes one user's model list to another caller during the TTL window.

Risk Assessment

The risk is unauthorized disclosure of AI model lists between users, potentially leaking information about available resources and user permissions.

Recommendation

Immediately upgrade Open WebUI to version 0.10.0 or later, which fixes the incorrect cache sharing.

Original NVD description (English source)

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.6.27 before 0.10.0, get_all_models handlers in routers/openai.py and routers/ollama.py passed a lambda to aiocache key instead of key_builder, causing permission-filtered per-user model lists to share a static cache entry and exposing one user’s model list to another caller during the TTL window. This issue is fixed in version 0.10.0.
