{"id":"CVE-2026-56692","summary":"NanoClaw \u003c 2.1.17 - Arbitrary File Read via Symlink Following in forwardAttachedFiles","details":"NanoClaw before 2.1.17 contains a symlink following vulnerability in forwardAttachedFiles that allows container-controlled agents to exfiltrate host-readable files. The host validates attachment filenames using only isSafeAttachmentName before copying with fs.copyFileSync, which follows symlinks without containment checks, allowing malicious agents to disclose arbitrary host files.","modified":"2026-07-15T01:48:53.474820003Z","published":"2026-06-23T15:34:56.366Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56692.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-59"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56692.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-56692"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/nanoclaw-arbitrary-file-read-via-symlink-following-in-forwardattachedfiles"},{"type":"REPORT","url":"https://github.com/nanocoai/nanoclaw/pull/2468"},{"type":"FIX","url":"https://github.com/nanocoai/nanoclaw/commit/28032bc0eca76c91fb3d8be0013e8bcaf2f5aeae"},{"type":"PACKAGE","url":"https://github.com/nanocoai/nanoclaw"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nanocoai/nanoclaw","events":[{"introduced":"0"},{"fixed":"ee7f891698760f21b9e79a850d64c7f633cd95ef"},{"fixed":"28032bc0eca76c91fb3d8be0013e8bcaf2f5aeae"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.1.17"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v2.0.64","v2.0.63","v2.0.54","v1.2.0","v1.1.6"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-56692.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
