Logged-in session tokens and account identifiers are sent to an unrelated host. The published admin password can be reused against the targeted PeerTube API. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 1.5.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. Installing the plugin runs author-controlled browser code on every page. That code loads an unpinned remote script and, by default, forwards a stored PeerTube access token, email, and username to developer-console.yakhub.com.tr. The server side also authenticates to the local PeerTube API with a published admin password. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-09-28T00:02:45.255Z - **Finished:** 2026-09-28T00:04:25.909Z - **Download time:** 504 ms - **Static scan time:** 158 ms - **AI review time:** 99991 ms - **Total time:** 100654 ms The recorded confidence comes from the underlying analysis.

That code loads an unpinned remote script and, by default, forwards a stored PeerTube access token, email, and username to developer-console.yakhub.com.tr. The server side also authenticates to the local PeerTube API with a published admin password. - **Trigger:** PeerTube loads the common client script after the plugin is enabled. Search-history sync runs at startup when a token is present. The admin password is used when the import route runs. - **Impact:** Visitors execute remote JavaScript chosen by the package author. Logged-in session tokens and account identifiers are sent to an unrelated host. The published admin password can be reused against the targeted PeerTube API. - **Evidence paths:** package.json, client.js, main.js - **Review source:** ai\_review - **Reviewed:** 2026-09-28T00:04:25.909Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** client.js appends a script tag for the latest file on cdnjs.yakhub.com.tr, opens a hidden SSO iframe, and fetches the author search-history API with the local bearer token. main.js posts a hardcoded password grant to 127.0.0.1 port 9000. - **Attack narrative:** After a PeerTube admin enables the plugin, every visitor loads client.js. That script pulls an unpinned account bundle from the author CDN and, when a local access token exists, sends the token, email, and username to developer-console.yakhub.com.tr unless the user previously set sync off. A hidden SSO frame and an origin-unchecked message handler can also drive login or session clearing. Separately, the import handler logs into the local API as a fixed admin account using a password shipped in the package. - **Rationale:** The common client entry loads unpinned remote code and, by default, forwards the stored PeerTube bearer token, email, and username to a package-controlled host. A fixed admin password in main.js is an additional concrete credential backdoor against the local PeerTube API. - **Network endpoints:** https://cdnjs.yakhub.com.tr/ajax/libs/yaknet-account/latest/yaknet-account.js, https://developer-console.yakhub.com.tr/sdk/sso-frame, https://developer-console.yakhub.com.tr/api/yaktube/search-history, http://127.0.0.1:9000/api/v1/users/token ### Review decision - **Verdict:** Malicious - **Confidence:** 92.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json registers client.js with PeerTube scope common, so the browser script runs on every page of an instance that installs the plugin., On load, client.js inserts an unpinned script from https://cdnjs.yakhub.com.tr/.../yaknet-account/latest/yaknet-account.js., If a local access token exists, startup search-history sync sends that token, email, and username to https://developer-console.yakhub.com.tr/api/yaktube/search-history. Sync stays on unless localStorage is explicitly false., main.js requests a local PeerTube admin token with a fixed username and password against 127.0.0.1:9000 and a Host header for yaktube.yakhub.com.tr., A hidden iframe loads the author SSO frame, and the message listener acts on YAKNET\_SSO\_STATUS without checking the sender origin. - **Evidence against:** package.json has no preinstall, install, or postinstall hook and no dependency on its own package name., YouTube search uses execFile with a fixed argument list and a YouTube URL check before import., The admin password grant runs only when the import route is called, not during npm install. ## Affected versions and remediation This report applies to peertube-plugin-yaktube-ondemand@1.5.2. - Avoid installing peertube-plugin-yaktube-ondemand@1.5.2. 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.
