HTML injection in Vox Media's Chorus CMS.

MEDIUM 4.8EPSS 0.31%

Does this matter?

Lower severity and a low EPSS score (0.31%). Track it; it rarely justifies an emergency change on its own.

Description

HTML injection in Vox Media's Chorus CMS. This vulnerability allows an attacker to execute JavaScript code in the victim's browser by sending them a malicious URL using the 'q' parameter in '/search'. This vulnerability can be exploited to steal sensitive user data, such as session cookies, or to perform actions on behalf of the user.
