CVE-2021-32924

CWE-94Published: June 1, 2021· Updated: Jun 17, 2026

8.8

CVSS v3.1

Official Description

Invision Community (aka IPS Community Suite) before 4.6.0 allows eval-based PHP code injection by a moderator because the IPS\cms\modules\front\pages\_builder::previewBlock method interacts unsafely with the IPS\_Theme::runProcessFunction method.

Technical Analysis

CVE-2021-32924 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
