Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The RSS reader widget in IBM Lotus Notes 8.0 and 8.5 saves items from an RSS feed as local HTML documents, which allows remote attackers to execute arbitrary script in Internet Explorer's Local Machine Zone via a crafted feed, aka SPR RGAU7RDJ9K.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The RSS reader widget in IBM Lotus Notes 8.0 and 8.5 saves items from RSS feeds as local HTML documents without sanitization. A remote attacker can craft a malicious RSS feed containing arbitrary script that will execute in Internet Explorer's Local Machine Zone when the saved HTML document is opened, achieving script execution with elevated privileges.

MitigationDisable or remove the RSS reader widget functionality in affected Lotus Notes installations. If RSS functionality is required, ensure feeds only come from trusted sources and consider upgrading to a patched version of Lotus Notes.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed Lotus Notes version
    Open Lotus Notes and navigate to Help > About IBM Lotus Notes, or check the program's version information through the Windows installed programs list. Look for version 8.0 or 8.5.
    Affected if The installed version is 8.0 or 8.5.
  2. Locate the RSS reader widget
    Open the Lotus Notes client and look for the RSS Reader widget or feed functionality in the sidebar or widget panel. Check if the RSS Reader is listed among available widgets or bookmarked items.
    Affected if The RSS reader widget is present and accessible in the Lotus Notes interface.
  3. Determine if RSS feeds have been added
    Open the RSS reader widget if present, and check the feed list to see if any RSS feeds have been configured and subscribed to.
    Affected if One or more RSS feeds are subscribed to in the RSS reader.
  4. Check for saved RSS HTML documents
    Search the local file system for HTML files that may have been saved by the RSS reader. Common locations include the Lotus Notes data directory or user documents folder. Look for recently created HTML files originating from RSS feed items.
    Affected if HTML documents saved by the RSS reader exist on the local system.

A user is affected if they have Lotus Notes version 8.0 or 8.5 installed with the RSS reader widget enabled and have subscribed to at least one RSS feed, as this creates the conditions for the unsanitized HTML document saving vulnerability to be exploitable.
