When a user opens the malicious repository and sends any message, the agent triggers a git status index refresh which executes the injected command in the user's process context, exposing the full environment including configured provider API keys.","published":"2026-09-03T16:18:21.710","modified":"2026-09-03T16:18:21.710","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/NousResearch/hermes-agent/commit/f6234d00c5d59450adea1d7edd30ad3859375c79","label":"NousResearch/hermes-agent@f6234d0"},"references":[{"type":"WEB","url":"https://github.com/NousResearch/hermes-agent/commit/f6234d00c5d59450adea1d7edd30ad3859375c79"},{"type":"WEB","url":"https://github.com/NousResearch/hermes-agent/pull/101483"},{"type":"WEB","url":"https://www.manifold.security/blog/ai-coding-agents-git-hijack"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/hermes-agent-rce-via-git-core-fsmonitor-config-injection"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-03T16:18:21.710"}}
