Prior to 0.3.0, the shared shell-command parser in omnigent/policies/builtins/_shell.py fails to recognize combined interpreter flags, the timeout, nice, setsid, and stdbuf wrappers, command substitutions, and a single background control operator. A gated git push or gh write hidden with these forms produces no parsed operation, causing the github.py write_repos and write_branches allowlist and the working_dir.py workspace confinement policies to abstain and allow the command. An authenticated or prompt-injected agent can therefore push to an unauthorized repository or branch or escape the intended workspace. This issue is fixed in version 0.3.0.","published":"2026-08-21T18:16:49.743","modified":"2026-08-21T18:16:49.743","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/omnigent-ai/omnigent/commit/1a05b7b139ef504bf2be89bf37918abe104fb95c","label":"omnigent-ai/omnigent@1a05b7b"},"references":[{"type":"WEB","url":"https://github.com/omnigent-ai/omnigent/commit/1a05b7b139ef504bf2be89bf37918abe104fb95c"},{"type":"WEB","url":"https://github.com/omnigent-ai/omnigent/pull/389"},{"type":"WEB","url":"https://github.com/omnigent-ai/omnigent/releases/tag/v0.3.0"},{"type":"WEB","url":"https://github.com/omnigent-ai/omnigent/security/advisories/GHSA-7mqg-cx4g-x2rf"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-21T18:16:49.743"}}
