Prior to 0.3.0, an authenticated user can upload a session-scoped agent bundle with an absolute or traversal-containing os_env.cwd value because omnigent/spec/parser.py stores the value verbatim and omnigent/spec/validator.py does not constrain it. On a runner where OMNIGENT_RUNNER_WORKSPACE is unset, omnigent/runner/resource_registry.py preserves the attacker-controlled path and omnigent/inner/os_env.py uses the resolved path as the environment root and copytree source. The _assert_within_cwd check then treats that attacker-selected root as trusted, allowing sys_os_read, write, edit, and shell tools to access runner files and environment secrets outside the intended workspace. This issue is fixed in version 0.3.0.","published":"2026-08-21T18:16:49.887","modified":"2026-08-21T18:16:49.887","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/omnigent-ai/omnigent/commit/7ca0cca3c9a65c04c489edf68f0e080424a26868","label":"omnigent-ai/omnigent@7ca0cca"},"references":[{"type":"WEB","url":"https://github.com/omnigent-ai/omnigent/commit/7ca0cca3c9a65c04c489edf68f0e080424a26868"},{"type":"WEB","url":"https://github.com/omnigent-ai/omnigent/pull/1417"},{"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-p8rw-8qj3-hf33"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-21T18:16:49.887"}}
