Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The cloud workflow transfers saved third-party credentials to a package-selected service without recipient-specific consent. This is concrete credential exfiltration and warrants blocking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-22T21:09:57.047Z - **Finished:** 2026-10-22T21:13:11.475Z - **Download time:** 1022 ms - **Static scan time:** 2293 ms - **AI review time:** 191111 ms - **Total time:** 194428 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The cloud snapshot flow stages saved Claude and Codex credentials and sends the archive to the package’s default cloud service. The source does not ask for recipient-specific consent to share these provider credentials. - **Trigger:** Running \`rudder cloud\` or \`rudder cloud --snapshot\` in a repository without a GitHub origin enters snapshot attachment. - **Impact:** A remote cloud workspace receives saved third-party login credentials and can use those accounts as the user. - **Evidence paths:** dist/main.js, dist/cloud.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T21:13:11.475Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Snapshot defaults include Claude’s credentials file and Codex’s auth file. When the cloud vault is inactive, those files—and on macOS Claude’s Keychain token—are included in an archive sent to the cloud endpoint. - **Attack narrative:** When the user runs the cloud command for a repository without a GitHub origin, the package builds a snapshot containing default home paths, including Claude’s saved OAuth credentials and Codex’s authentication file. If no cloud vault is active, those credentials are included; on macOS, Claude’s Keychain token is also staged. The archive is sent to the package’s fixed cloud endpoint without asking whether these third-party credentials may be shared. - **Rationale:** The cloud workflow transfers saved third-party credentials to a package-selected service without recipient-specific consent. This is concrete credential exfiltration and warrants blocking. - **Files touched:** dist/cloud.js, ~/.claude/.credentials.json, ~/.codex/auth.json - **Network endpoints:** https://rudder-cloud-control.fly.dev, /api/rudder/workspace/attach ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The CLI routes \`rudder cloud\`; its default and snapshot forms reach snapshot attachment when the repository lacks a GitHub origin., The snapshot’s default home-path list includes Claude’s saved credentials and Codex’s authentication file, and normalization retains those defaults., Snapshot creation includes home credentials by default; on macOS it also stages Claude’s Keychain OAuth token as a credentials file., Without an active cloud vault, the workspace snapshot sets credential inclusion to true; vault lookup failure falls back to legacy snapshot behavior., The archive is included as base64 in a request to the package’s default cloud service at \`/api/rudder/workspace/attach\`. ## Affected versions and remediation This report applies to @exla/rudder@3.9.6. - Avoid installing @exla/rudder@3.9.6. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
