{"id":"GHSA-3c6j-hq33-3jv4","summary":"OpenClaw: Paired nodes could forge exec lifecycle events without system.run provenance","details":"### Summary\n\nOpenClaw nodes send lifecycle events back to the gateway. In affected releases, a paired node could send an exec lifecycle event that was accepted without enough provenance tying it to an authorized `system.run` request.\n\nThis issue affects the node event boundary. It does not allow an unauthenticated caller to reach the gateway; the attacker must already control a paired node connection.\n\n### Affected configurations\n\nThis affects deployments with a paired node where that node can send crafted `node.event` messages to the gateway and the target agent/session can process exec lifecycle events.\n\n### Impact\n\nA malicious or compromised paired node could make the gateway treat attacker-supplied event data as an exec lifecycle result. In the vulnerable flow, that could steer the target session into an exec-event path that exposed capabilities the reduced node surface should not have provided.\n\nThe issue is a missing provenance check for node-originated lifecycle events.\n\n### Patched Versions\n\nThe first stable patched version is `2026.5.18`.\n\n### Mitigations\n\nUpgrade to `openclaw@2026.5.18` or later. Pair nodes only from trusted environments, and remove/re-pair nodes that may have been compromised.","aliases":["CVE-2026-53816"],"modified":"2026-07-02T17:26:32.187947Z","published":"2026-07-02T17:12:03Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-07-02T17:12:03Z","nvd_published_at":"2026-06-11T21:16:23Z","cwe_ids":["CWE-284","CWE-862","CWE-863"]},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-3c6j-hq33-3jv4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53816"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-exec-lifecycle-event-forgery-via-paired-node"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.5.18"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-3c6j-hq33-3jv4/GHSA-3c6j-hq33-3jv4.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
