NVD description
Ollama versions 0.14.0 before 0.31.2 contain an incorrect authorization vulnerability in the experimental agent mode Bash tool approval mechanism that fails to properly parse shell syntax. Attackers who can influence model output through prompt injection can execute additional shell commands by appending control operators like semicolons or logical operators to approved commands, bypassing the session approval requirement.
What to do
- NVD lists no fixed version yet: follow the vendor advisory below and keep Ollama off the public internet until a fix ships.
- Do not expose the component's API or UI to the internet without authentication in front of it.
