Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Jcbrand/converse.js, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Converse.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.
