{"id":"CVE-2026-7875","summary":"NanoClaw Host/Container Filesystem Boundary Vulnerability via Outbound Attachment Handling","details":"NanoClaw version 1.2.0 and prior contains a host/container filesystem boundary vulnerability in outbound attachment handling and outbox cleanup that allows a compromised or prompt-injected container to read files outside the intended outbox directory by supplying crafted messages_out.id and content.files values or creating symlinked outbox files. Attackers can exploit this vulnerability to trigger host-side reads of arbitrary files and in some cases achieve recursive deletion of paths outside the intended cleanup target.","modified":"2026-08-12T03:51:31.142684850Z","published":"2026-05-06T16:10:46.270Z","database_specific":{"cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/7xxx/CVE-2026-7875.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/7xxx/CVE-2026-7875.json"},{"type":"ADVISORY","url":"https://github.com/qwibitai/nanoclaw/releases/tag/v1.2.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-7875"},{"type":"REPORT","url":"https://github.com/qwibitai/nanoclaw/pull/2001"},{"type":"FIX","url":"https://github.com/qwibitai/nanoclaw/commit/7814e45570edf0024a1a5c2ba9fbc9cb3a49f7f7"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nanocoai/nanoclaw","events":[{"introduced":"0"},{"fixed":"7814e45570edf0024a1a5c2ba9fbc9cb3a49f7f7"},{"fixed":"0210aa9ef169401aa5c8d85e002c2e8976f69253"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:nanoco:nanoclaw:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"1.2.0"}]}}],"versions":["v1.2.0","v1.1.6"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-7875.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H"}]}
