Deeper analysis

CVE-2024-38457 is a cross-site request forgery vulnerability, tracked as CWE-352, that affects Xenforo versions prior to 2.2.16. The flaw carries a CVSS 3.1 base score of 8.8, reflecting network attack vector, low attack complexity, no required privileges, and required user interaction, with high impact across confidentiality, integrity, and availability.

An unauthenticated remote attacker can exploit the issue by crafting a malicious request that an authenticated Xenforo user is tricked into submitting, allowing the attacker to perform arbitrary actions on the victim's behalf within the forum application.

Official advisories from Xenforo detail the release of version 2.2.16 (along with patch releases for the 2.1 branch and Xenforo Media Gallery) that incorporate fixes for this and related security issues; full-disclosure postings on Seclists reference the same patched releases. The associated EPSS score has remained flat at 0.0656 with no material increase observed after disclosure.
