CVE-2025-46595
Medium 6.4
In plain English
A medium-severity cross-site scripting in Flag from backdropcms. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 16% of all known vulnerabilities).
Official description
An XSS issue was discovered in the Flag module before 1.x-3.6.2 for Backdrop CMS. Flag is a module that allows flags to be added to nodes, comments, users, and any other type of entity. It doesn't verify flag links before performing the flag action, or verify that the response returned was provided by the flag module. This can allow crafted HTML to result in Cross Site Scripting. This is mitigated by the fact that an attacker must have a role with permission to create links on the website, for example: create or edit comments or content with a filtered text format.
