Attackers can exploit this by placing symlinks in the media/inbound directory to overwrite arbitrary files on the host system outside sandbox boundaries.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":7.1},"cwes":["CWE-59"],"references":["https://github.com/openclaw/openclaw/commit/17ede52a4be3034f6ec4b883ac6b81ad0101558a","https://github.com/openclaw/openclaw/security/advisories/GHSA-cfvj-7rx7-fc7c","https://www.vulncheck.com/advisories/openclaw-symlink-traversal-in-stagesandboxmedia-destination"],"products":["openclaw:openclaw"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-31990","score":0.00139,"percentile":0.0325,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cfvj-7rx7-fc7c","url":"https://osv.dev/vulnerability/GHSA-cfvj-7rx7-fc7c","summary":"OpenClaw: stageSandboxMedia destination symlink traversal can overwrite files outside sandbox workspace","modified":"2026-03-19T21:41:21.211376Z","packages":[{"ecosystem":"npm","name":"openclaw","purl":"pkg:npm/openclaw","ranges":["<2026.3.2"],"fixed":["2026.3.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
