Frequently Asked Questions
What is CVE-2026-100547?
OpenClaw is a coding agent distributed as the npm package `openclaw`. In affected versions (2026.7.1 through 2026.7.2), alternate but valid `file:` URL spellings supplied over the Agent Client Protocol (ACP) were treated as relative paths and were incorrectly classified as reads scoped to the session working directory. When an operator connected `openclaw acp client` to an untrusted or compromised ACP peer, that peer could request a read of a file outside the session working directory without the approval prompt normally required for that path, resulting in disclosure of local file contents. The demonstrated impact is limited to file confidentiality; mutating and command-capable tool classes are not affected. This issue is fixed in OpenClaw 2026.8.1.
Is CVE-2026-100547 actively exploited?
No confirmed active exploitation of CVE-2026-100547 has been reported, but organizations should still patch proactively.

Weaknesses (CWE)
CWE-180 — Incorrect Behavior Order: Validate Before Canonicalize: The product validates input before it is canonicalized, which prevents the product from detecting data that becomes invalid after the canonicalization step.
- [Implementation] Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
