Subject: CVE-2026-73192: Apache Sling XSS: XSS possible through
XSSAPI.getValidHref()
Severity: low
Affected versions:
- Apache Sling XSS before 2.4.12
Description:
An improper neutralization of input during web page generation ('Cross-site Scripting') [CWE-79] vulnerability when using the XSSAPI.getValidHref() in Apache Sling XSS version 2.4.10 and prior may allow an attacker to perform a reflected cross-site scripting (XSS) attack in every feature using this method. In order to successfully attack an application, the attacker needs to be able to submit a value which is not correctly sanitized by that library.
Upgrade to Apache Sling XSS >= 2.4.12
