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. The published theme files are a live browser payload. Applying style.css or loading payload.js steals session data and talks to an out-of-band host plus Infomaniak manager APIs. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-18T03:16:20.263Z - **Finished:** 2026-09-18T03:18:03.450Z - **Download time:** 510 ms - **Static scan time:** 7 ms - **AI review time:** 102669 ms - **Total time:** 103187 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 published theme files are a live browser payload. Applying style.css or loading payload.js steals session data and talks to an out-of-band host plus Infomaniak manager APIs. - **Trigger:** A page applies style.css as a stylesheet or loads payload.js as a script, including through a CDN import. - **Impact:** Victim session cookies and XSRF material can leak, and the victim browser can make authenticated Infomaniak manager API requests. - **Evidence paths:** package.json, payload.js, style.css - **Review source:** ai\_review - **Reviewed:** 2026-09-18T03:18:03.450Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** CSS url() session probes plus XSS cookie and XSRF beacons - **Attack narrative:** This package is published as a radio player theme so a victim page can import it, including from a public CDN. Once style.css is applied, CSS url() rules fire authenticated requests to Infomaniak manager APIs and leak form values through attribute selectors. If payload.js is loaded, it reads cookies and the manager XSRF token, beacons the origin to an oastify collaborator, and hits the same manager API. The bug-bounty wording does not change that this is a live credential and session-theft payload. - **Rationale:** The package ships a live CSS and XSS command-and-control payload that steals cookies and XSRF tokens and drives authenticated Infomaniak manager requests. Calling it a bug-bounty proof does not make that behavior a legitimate theme. - **Files touched:** payload.js, style.css - **Network endpoints:** https://bfuntjuvcnxl49hcbpklk3ube2ks8h.oastify.com, https://manager.infomaniak.com/v3/api/proxypass\_2/XSS-CONFIRMED-RADIO-CDNJSDELIVR-BYPASS, https://manager.infomaniak.com/v3/api/proxypass\_2/1/radios/18409/players/5816, https://manager.infomaniak.com/v3/api/proxypass\_2/css-c2-exfil/uuid/6ce06ce3-62f6-4d33-CONFIRMED, https://manager.infomaniak.com/v3/api/proxypass\_2/css-font-probe-SASESSION ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Package metadata describes a live C2 XSS and CSS-injection payload, not a theme., payload.js reads document cookies and the Infomaniak manager XSRF token, then beacons the page origin to an oastify collaborator., payload.js also fires an authenticated image request to the Infomaniak manager API., style.css uses background-image, SVG fill, and @font-face urls to force authenticated GETs to Infomaniak manager APIs., CSS attribute selectors leak a share-input UUID to a C2 confirmation URL., Comments present this as a jsdelivr CSP-bypass and CSS-injection delivery vector. - **Evidence against:** package.json has no preinstall, install, or postinstall scripts., Nothing in this package runs under Node just from npm install. ## Affected versions and remediation This report applies to radio-player-theme@6.0.0. - Avoid installing radio-player-theme@6.0.0. 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.
