{"cve":"CVE-2026-62677","nvd":{"published":"2026-08-21T18:16:49.887","modified":"2026-10-14T19:10:00.297","status":"Deferred","description":"Omnigent is an open-source AI agent framework and meta-harness for orchestrating coding agents. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-22"],"references":["https://github.com/omnigent-ai/omnigent/commit/7ca0cca3c9a65c04c489edf68f0e080424a26868","https://github.com/omnigent-ai/omnigent/pull/1417","https://github.com/omnigent-ai/omnigent/releases/tag/v0.3.0","https://github.com/omnigent-ai/omnigent/security/advisories/GHSA-p8rw-8qj3-hf33"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-62677","score":0.00606,"percentile":0.48704,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-p8rw-8qj3-hf33","url":"https://osv.dev/vulnerability/GHSA-p8rw-8qj3-hf33","summary":"Omnigent: Unvalidated os_env.cwd in agent bundle yields arbitrary host filesystem access on runners without OMNIGENT_RUNNER_WORKSPACE","modified":"2026-09-10T12:25:35.012514928Z","packages":[{"ecosystem":"PyPI","name":"omnigent","purl":"pkg:pypi/omnigent","ranges":["<0.3.0"],"fixed":["0.3.0"]}]},{"id":"PYSEC-2026-3875","url":"https://osv.dev/vulnerability/PYSEC-2026-3875","summary":"Omnigent: Unvalidated os_env.cwd in agent bundle yields arbitrary host filesystem access on runners without OMNIGENT_RUNNER_WORKSPACE","modified":"2026-09-10T12:15:10.115299270Z","packages":[{"ecosystem":"PyPI","name":"omnigent","purl":"pkg:pypi/omnigent","ranges":["<0.3.0"],"fixed":["0.3.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
