This can give bot-controlled prompts unrestricted local-agent execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 94.0% - **Started:** 2026-08-28T10:28:24.103Z - **Finished:** 2026-08-28T10:30:27.254Z - **Download time:** 505 ms - **Static scan time:** 8409 ms - **AI review time:** 114233 ms - **Total time:** 123151 ms ## Security analysis ### Published attack-surface review - **Summary:** The runtime bridge masks identifiers and launches Claude with its permission checks disabled. This can give bot-controlled prompts unrestricted local-agent execution. - **Trigger:** Starting the bot with the Claude bridge provider and processing a request. - **Impact:** A prompt reaching the bridge can act through the local Claude CLI without its normal approval controls. - **Evidence paths:** claude-bridge/src/claude.js, dist/index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-28T10:30:27.254Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Identifier masking plus unconditional permission-bypass execution. - **Attack narrative:** The package includes a Claude bridge that rewrites OpenClaw identifiers before sending prompts onward, then starts the local Claude CLI with the dangerous permission-bypass flag. The source explicitly describes the rewriting as a detection bypass. Although npm installation itself has no automatic lifecycle hook, running the configured bot activates this bridge and exposes the local agent environment to unrestricted actions from processed requests. - **Rationale:** The deliberate concealment and unconditional disabling of a foreign AI agent's permission guard are concrete harmful runtime behavior. The absence of an install hook reduces scope but does not neutralize the runtime control bypass. - **Files touched:** /tmp ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The bundled bridge disguises OpenClaw names and labels this as a detection bypass., The bridge always invokes the Claude CLI with permissions disabled., Published runtime files are deliberately obfuscated, preventing normal source review. - **Evidence against:** package.json has no npm install, preinstall, or postinstall hook., The dangerous bridge is reached at runtime rather than automatically during npm installation. ## Public findings ### 1.
