Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Ollama (Go module github.com/ollama/ollama) versions up to and including 0.9.6 are affected. A remote attacker who can get Ollama to pull from a server they control, such as through the /api/pull endpoint, can supply a malicious realm value in a WWW-Authenticate header and cause Ollama to send authentication tokens to that realm, which can allow access control bypass. No fixed version is listed.
