It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-19590 in the wild and no public exploit code.\n\nAffected product: OpenAI Codex Desktop. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-19590/ (Markdown: https://insights.sbomify.com/CVE-2026-19590/index.md)","id":"CVE-2026-19590","markdown":"https://insights.sbomify.com/CVE-2026-19590/index.md","name":"CVE-2026-19590","record":{"aliases":["GHSA-433v-pqvh-w4gj"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenAI Codex Desktop","requires_auth":"low_privilege","summary":"OpenAI Codex Desktop allows arbitrary code execution via malicious Git hooks when opening attacker-controlled repositories, bypassing sandbox restrictions.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OAI","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-427","name":"Uncontrolled Search Path Element"}],"description":"OpenAI Codex Desktop for Windows and macOS could execute attacker-controlled Git hooks because automated Git operations trusted the repository's local core.hooksPath setting. If a user opens an attacker-prepared repository whose preserved .git/config points core.hooksPath to an attacker-controlled directory, Codex can run a malicious hook while processing the repository. The hook executes outside Codex's command sandbox, without user approval, and with the user's privileges, allowing it to read, change, or delete the user's files and access other resources available to the user's account. An ordinary Git clone does not preserve the attacker-controlled repository-local configuration required for exploitation.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Code injection in Codex Desktop","id":"CVE-2026-19590","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in Codex CLI","id":"CVE-2026-19591"},"packages":[],"prev":{"headline":"Packer vulnerable to arbitrary file write via crafted plugin archive during installation","id":"CVE-2026-19589"},"products":["Codex Desktop","Codex Desktop (Microsoft Store package)"],"published":"2026-09-01","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-03","vendors":["OpenAI"]},"summary":"OpenAI Codex Desktop allows arbitrary code execution via malicious Git hooks when opening attacker-controlled repositories, bypassing sandbox restrictions.","url":"https://insights.sbomify.com/CVE-2026-19590/"}
