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: `<= 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.","published":"2026-03-21T00:42:33.718Z","modified":"2026-08-12T03:51:46.696622770Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.23"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/12cc754332f9a7c92e158ce7644aa22df79c0904","label":"openclaw/openclaw@12cc754"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32898.json"},{"type":"ADVISORY","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":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-acp-permission-auto-approval-bypass-via-untrusted-tool-metadata"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/12cc754332f9a7c92e158ce7644aa22df79c0904"},{"type":"FIX","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:46.696622770Z"}}
