{"apiVersion":"1.0","identifier":"CVE-2026-62677","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.","publishedAt":"2026-08-21T18:16:49","lastModifiedAt":"2026-08-21T22:16:41","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-62677","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00446,"riskScore":0.92,"affectedProduct":"Omnigent","affectedVersions":"<0.3.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-62677","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-62677","en":"https://www.redsauce.net/en/cves/CVE-2026-62677","fr":"https://www.redsauce.net/fr/cves/CVE-2026-62677","pt":"https://www.redsauce.net/pt/cves/CVE-2026-62677","de":"https://www.redsauce.net/de/cves/CVE-2026-62677","sk":"https://www.redsauce.net/sk/cves/CVE-2026-62677","el":"https://www.redsauce.net/el/cves/CVE-2026-62677"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-62677"}}
