{"id":"GHSA-7jx5-9fjg-hp4m","summary":"OpenClaw ACP client has permission auto-approval bypass via untrusted tool metadata","details":"## Vulnerability Summary\n\nThe OpenClaw ACP client could auto-approve tool calls based on untrusted metadata and permissive name heuristics. A malicious or compromised ACP tool invocation could bypass expected interactive approval prompts for read-class operations.\n\n## Affected Packages / Versions\n\n- Package: npm `openclaw`\n- Affected published versions: `\u003c= 2026.2.22-2` (latest published as of February 24, 2026 is `2026.2.22-2`)\n- Patched in code on `main`: `2026.2.23` (released)\n\n## Technical Details\n\n- Permission classification trusted incoming `toolCall.kind` and heuristic name matching.\n- Non-core read-like names and spoofed kind metadata could reach auto-approve paths.\n- `read` operations were not scoped strongly enough to cwd in all metadata/title forms.\n\n## Fix\n\n- Require trusted core tool IDs for auto-approval and ignore untrusted `toolCall.kind` as an authorization source.\n- Scope `read` auto-approval to cwd-resolved paths.\n- Add stricter tool-name validation and regression coverage for spoofed kind and non-core read-like names.\n\n## Affected Functions\n\n- `resolvePermissionRequest`\n- `resolveToolNameForPermission`\n- `shouldAutoApproveToolCall`\n\n## Fix Commit(s)\n\n- `12cc754332f9a7c92e158ce7644aa22df79c0904`\n- `63dcd28ae0be2de1c75af09cc81841cebeec068f`\n\nFound using [MCPwner](https://github.com/Pigyon/MCPwner)\n\n\nThanks @nedlir for reporting.","aliases":["CVE-2026-32898"],"modified":"2026-03-30T14:11:33.359385Z","published":"2026-02-27T22:08:36Z","database_specific":{"github_reviewed_at":"2026-02-27T22:08:36Z","nvd_published_at":null,"cwe_ids":["CWE-639","CWE-863"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-7jx5-9fjg-hp4m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32898"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/12cc754332f9a7c92e158ce7644aa22df79c0904"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/63dcd28ae0be2de1c75af09cc81841cebeec068f"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.2.23"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-acp-permission-auto-approval-bypass-via-untrusted-tool-metadata"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.23"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-7jx5-9fjg-hp4m/GHSA-7jx5-9fjg-hp4m.json","last_known_affected_version_range":"\u003c= 2026.2.22-2"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
