CVE-2026-108592 Details
Description
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.
A vulnerability allowing information exposure has been identified in mini-swe-agent versions 1.10.0 through 2.4.6. The issue arises in the BubblewrapEnvironment component, where the 'bwrap' sandboxing tool fails to clear the environment variables. As a result, commands executed within the sandbox inherit the host environment, including sensitive information such as API keys. This vulnerability can be exploited by attackers through prompt injection in task content, enabling them to read and exfiltrate these keys over the network.
The vulnerability can be addressed by updating the default Bubblewrap wrapper arguments to include '--clearenv' and '--unshare-net', ensuring that the sandbox does not inherit host environment variables or have network access by default.
