CVE-2026-59213
Last modified
CVE-2026-59213 is a medium-severity vulnerability rated 5/10 on the CVSS scale. 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. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
