There is no exported helper API. - **Trigger:** Requiring, importing, or bundling the package main entry index.js, typically in a browser on a matching origin. - **Impact:** A signed-in user's profile page can be read and published as a new post using their cookies. - **Evidence paths:** index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-17T01:04:16.141Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Same-origin profile harvest posted to addPost - **Attack narrative:** Importing this package immediately requests the same-origin Profile page and posts that response as the content of a new addPost call. The module exports nothing and is not wrapped in a function, so any app that bundles the main entry will run this in the browser with the user's cookies. That is a harvest-and-publish of profile data, not a feed widget helper. - **Rationale:** The published main module is only an import-time fetch of /Profile followed by a POST of that body to /addPost, with no helper API. Combined with an empty manifest and no install hooks, this is a same-origin data theft gadget rather than a legitimate widget. - **Network endpoints:** /Profile, /addPost ### Review decision - **Verdict:** Malicious - **Confidence:** 86.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js runs fetch at module load with no exports or function wrapper, It GETs /Profile then POSTs that response body to /addPost as JSON content, package.json main is index.js, so import or bundle of the package triggers the requests, Empty description and author, and no helper API; the package is only this side effect - **Evidence against:** No npm preinstall, install, or postinstall scripts, No hardcoded remote host, child\_process, eval, or filesystem credential reads, Relative URLs only resolve when a browser same-origin base URL exists ## Affected versions and remediation This report applies to feed-widget-helper@1.0.2. - Avoid installing feed-widget-helper@1.0.2. 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.
