WEB APPLICATION VULNERABILITIES Standard & Premium

MediaWiki Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') Vulnerability (CVE-2020-26120)

Description

XSS exists in the MobileFrontend extension for MediaWiki before 1.34.4 because section.line is mishandled during regex section line replacement from PageGateway. Using crafted HTML, an attacker can elicit an XSS attack via jQuery's parseHTML method, which can cause image callbacks to fire even without the element being appended to the DOM.
