CVE-2026-45003

Connector traffic redirection via workspace dotenv overrides

Published May 11, 2026 · Updated May 11, 2026

External resource control in OpenClaw before 2026.4.22 allows local users with workspace access to redirect connector traffic. The workspace dotenv loader accepted Matrix, Mattermost, IRC, and Synology endpoint variables without excluding them from the lower-trust workspace source. Local users must write the active workspace .env file and induce connector use, after which the malicious endpoint receives the redirected traffic.
