Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Loading the package stylesheet in the targeted administrative page causes browser requests to a player API endpoint and conditionally signals a matching player identifier. The shipped script can read a non-HttpOnly XSRF cookie and trigger another authenticated request if separately executed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-14T00:36:54.704Z - **Finished:** 2026-09-14T00:37:36.400Z - **Download time:** 252 ms - **Static scan time:** 13 ms - **AI review time:** 41430 ms - **Total time:** 41696 ms The recorded confidence comes from the underlying analysis.

The shipped script can read a non-HttpOnly XSRF cookie and trigger another authenticated request if separately executed. - **Trigger:** A consumer loads style.css in the targeted administrative page; payload.js requires separate script execution. - **Impact:** Unauthorized authenticated requests and disclosure of targeted page state; the optional script can expose an XSRF token to page JavaScript. - **Evidence paths:** package.json, style.css, payload.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T00:37:36.400Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** CSS request-based data signaling and a browser cookie-reading beacon payload. - **Attack narrative:** The package presents a stylesheet as its entry point, but that stylesheet is an active browser-side request payload aimed at a named administrative service. It conditionally signals a player UUID and unconditionally requests a specific player endpoint. A separately shipped JavaScript payload reads document cookies, extracts an XSRF token, and sends an authenticated beacon. These actions are incompatible with a radio-player theme and create a concrete data-access attack surface. - **Rationale:** This is an intentionally targeted CSS and JavaScript attack package, not a theme. Its network requests and token-handling code establish malicious browser-side behavior even without an npm lifecycle hook. - **Files touched:** package.json, style.css, payload.js - **Network endpoints:** manager.infomaniak.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest exposes the malicious stylesheet as the package entry point and ships a JavaScript payload., The stylesheet makes a network request when a targeted share-input value matches a player UUID., The stylesheet unconditionally requests a specific player API path through the victim's browser., The shipped JavaScript reads browser cookies and an XSRF token, then sends a beacon to the target API. - **Evidence against:** There are no npm lifecycle scripts., The JavaScript payload is shipped but is not automatically loaded by the manifest. ## Affected versions and remediation This report applies to radio-player-theme@4.0.0. - Avoid installing radio-player-theme@4.0.0. 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.
