{"cve":"CVE-2026-62676","nvd":{"published":"2026-08-21T18:16:49.743","modified":"2026-10-14T21:10:00.183","status":"Deferred","description":"Omnigent is an open-source AI agent framework and meta-harness for orchestrating coding agents. 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.","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:L/A:N","score":7.1},"cwes":["CWE-184"],"references":["https://github.com/omnigent-ai/omnigent/commit/1a05b7b139ef504bf2be89bf37918abe104fb95c","https://github.com/omnigent-ai/omnigent/pull/389","https://github.com/omnigent-ai/omnigent/releases/tag/v0.3.0","https://github.com/omnigent-ai/omnigent/security/advisories/GHSA-7mqg-cx4g-x2rf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-62676","score":0.00402,"percentile":0.34183,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-7mqg-cx4g-x2rf","url":"https://osv.dev/vulnerability/GHSA-7mqg-cx4g-x2rf","summary":"Omnigent Guardrail policy bypass: shell-command parser fails open in policies/builtins/_shell.py","modified":"2026-09-10T12:25:30.446854519Z","packages":[{"ecosystem":"PyPI","name":"omnigent","purl":"pkg:pypi/omnigent","ranges":["<0.3.0"],"fixed":["0.3.0"]}]},{"id":"PYSEC-2026-3873","url":"https://osv.dev/vulnerability/PYSEC-2026-3873","summary":"Omnigent Guardrail policy bypass: shell-command parser fails open in policies/builtins/_shell.py","modified":"2026-09-10T12:15:09.111299206Z","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).
