OpenClaw version 2026.1.14-1 prior to 2026.2.12 contains an improper network binding vulnerability in the Chrome extension (must be installed and enabled) relay server that treats wildcard hosts as loopback addresses, allowing the relay HTTP/WS server to bind to all interfaces when a wildcard cdpUrl is configured. Remote attackers can access relay HTTP endpoints off-host to leak service presence and port information, or conduct denial-of-service and brute-force attacks against the relay token header.

- GHSA-qw99-grcx-4pvmOpenClaw's Chrome extension relay binds publicly due to wildcard treated as loopback2026-02-17ghsa · osvUS
## Summary The Chrome extension relay (`ensureChromeExtensionRelayServer`) previously treated wildcard hosts (`0.0.0.0` / `::`) as loopback, which could make it bind the relay HTTP/WS server to all interfaces when a wildcard `cdpUrl` was passed. ## Impact If configured with a wildcard `cdpUrl`, relay HTTP endpoints could become reachable off-host, leaking service presence/port and enabling DoS/brute-force traffic against the relay token header. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: `>= 2026.1.14-1 < 2026.2.12` ## Fixed Versions - Patched: `>= 2026.2.12` (released 2026-02-13) ## Fix Commit(s) - 8d75a496bf5aaab1755c56cf48502d967c75a1d0 ## Notes - Earlier hardening for `/json*` auth and `/cdp` token checks landed in: - a1e89afcc19efd641c02b24d66d689f181ae2b5c Thanks @qi-scape for reporting.
