From 0.13.2 until ag2 1.1.1, and from autogen 0.13.2 to 0.14.1, SandboxShellTool configurations using allowed=[...] or readonly=True rely on ShellAdapter._filter and contains_shell_operator in ag2/tools/sandbox/filter.py and ag2/tools/sandbox/adapter/shell.py to validate a command prefix and reject selected shell syntax. The filter omits newline and carriage-return separators, while the accepted raw string is passed to sh -c, allowing an attacker-influenced agent command to execute an additional arbitrary statement. With the default LocalEnvironment backend, the injected statement runs as a host subprocess with the privileges of the agent process and can affect confidentiality, integrity, and availability. This issue is fixed in ag2 version 1.1.1.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":8.8,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793919220444,"publishedAt":1793919220444,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/ag2ai/ag2/security/advisories/GHSA-2h4w-29cv-2cmv"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/ag2ai/ag2/commit/3cd86726bb731eb11d6270f0ef9e50e42b5abb39"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/ag2ai/ag2/releases/tag/v1.1.1"}],"remediation":[],"revision":"7b0f9c2c53d91b3f401a3d3ebbc439020590416c06cd9cfe47348451b8526f53","sources":[{"modifiedAt":1793919220444,"name":"CNA: GitHub_M","retrievedAt":1793920108270,"url":"https://www.cve.org/CVERecord?id=CVE-2026-113663"}],"ssvc":null,"status":"published","title":"AG2: Newline injection in SandboxShellTool bypasses allowed=[...] and readonly=True, enabling arbitrary command execution","updatedAt":1793920108270}
