CVE-2010-4536

CWE-79Published: January 3, 2011· Updated: Jun 16, 2026

4.3

CVSS v3.1

Official Description

Multiple cross-site scripting (XSS) vulnerabilities in KSES, as used in WordPress before 3.0.4, allow remote attackers to inject arbitrary web script or HTML via vectors related to (1) the & (ampersand) character, (2) the case of an attribute name, (3) a padded entity, and (4) an entity that is not in normalized form.

Technical Analysis

CVE-2010-4536 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

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

From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
