Summary

mini-swe-agent from 1.10.0 through 2.4.6 is affected. BubblewrapEnvironment runs bwrap without clearenv (CWE-526), so sandboxed commands inherit the host environment variables. An attacker who injects prompts into processed task content can make the agent read API keys from the environment and send them out over the shared network.

Description from the CNA

mini-swe-agent 1.10.0 through 2.4.6 contains an information exposure vulnerability in BubblewrapEnvironment because bwrap omits --clearenv, so sandboxed commands inherit the host environment. Attackers using prompt injection in processed task content can make the agent read API keys from the environment and exfiltrate them over the shared network.
