CVE-2018-6591
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 · uneditedConverse.js and Inverse.js through 3.3 allow remote attackers to obtain sensitive information because it is too difficult to determine whether safe publication of private data was configured or even intended. For example, users might have an expectation that chatroom bookmarks are private, but the various interacting software components do not necessarily make that happen.
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 · moderate confidenceConverse.js and Inverse.js through version 3.3 improperly handle private data (such as chatroom bookmarks), allowing remote attackers to obtain sensitive information. The vulnerability stems from unclear or missing safe publication configurations for private data, where users reasonably expect certain data to remain private but the software components do not enforce this protection.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Converse.js or Inverse.js installation and versionInspect your web application dependencies (package.json, bower.json, or loaded JavaScript files) to determine if Converse.js or Inverse.js is present and note the exact version numberAffected if The installed version is 3.3 or lower, or the version cannot be determined (indicating it may be an unpatched release)
-
Verify if chatroom bookmarks feature is in useCheck application logs, storage, or user session data for evidence of chatroom bookmark functionality being actively used or storing bookmarked room dataAffected if Chatroom bookmarks or similar private user data is being stored or managed by the application
-
Inspect data storage configuration for privacy settingsReview the application's configuration files or admin settings for any options related to data publication, privacy controls, or access restrictions on stored user dataAffected if No explicit privacy or access control settings are found, or settings are configured to allow broader data access than intended
-
Check for exposed API endpoints or data leaksReview network traffic or API documentation to identify if bookmarked chatroom data or other private information is accessible without proper authentication or authorizationAffected if Private data such as chatroom bookmarks is accessible to unauthenticated or unauthorized users
Your environment is affected if you are running Converse.js or Inverse.js version 3.3 or lower and you use the chatroom bookmarks or similar private data features without verified privacy protection configurations in place.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReview and configure safe publication settings to ensure private data like chatroom bookmarks cannot be accessed by unauthorized parties. Verify that all data expected to be private is properly protected through appropriate access controls and configuration.
