WordPress Core < 6.0.3 - Information Disclosure (Multi-Part Email Leak)

Exposure of Sensitive Information to an Unauthorized Actor
CVE Not available
CVSS Low (3.7)
Publicly Published October 18, 2022
Last Updated January 22, 2024
Researcher Thomas Kräftner
Description

WordPress Core is vulnerable to information disclosure via a REST-API endpoint in versions up to 6.0.3. The endpoint for terms and tags did not perform enough validation on the user requesting information about terms and tags for a given post. This made it possible for users with access to terms and tags, such as a contributor, to determine those details on all posts not belonging to them, even when in a private status. This does not reveal critical information, and as such it is not likely to be exploited.
