Summary

The tagDiv Composer WordPress plugin before 4.2, used as a companion by the Newspaper and Newsmag themes from tagDiv, does not have authorisation in a REST route and does not validate as well as escape some parameters when outputting them back, which could allow unauthenticated users to perform Stored Cross-Site Scripting attacks.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
