{"id":"GHSA-w626-296m-8f85","summary":"Duplicate Advisory: OpenClaw's ACP child sessions inherit subagent security envelope constraints","details":"### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-q3jj-46pq-826r. This link is maintained to preserve external references.\n\n### Original Description\nOpenClaw before 2026.4.22 contains a security envelope constraint bypass vulnerability allowing restricted subagents to spawn ACP child sessions that fail to inherit depth, child-count limits, control scope, or target-agent restrictions. Attackers can exploit this by spawning child sessions that bypass subagent-only constraints, potentially escalating privileges or accessing restricted resources.","modified":"2026-05-18T15:49:43.302261Z","published":"2026-05-11T18:31:46Z","withdrawn":"2026-05-18T15:29:59Z","database_specific":{"github_reviewed_at":"2026-05-18T15:29:59Z","nvd_published_at":"2026-05-11T18:16:39Z","cwe_ids":["CWE-266"],"severity":"LOW","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-q3jj-46pq-826r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44997"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/31160dc069b7cc5d833b39c53736a41ad3befda2"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-security-envelope-constraint-bypass-in-acp-child-sessions"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.4.22"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-w626-296m-8f85/GHSA-w626-296m-8f85.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
