CVE-2024-24815

CKEditor4 is an open source what-you-see-is-what-you-get HTML editor. A
cross-site scripting vulnerability has been discovered in the core HTML
parsing module in versions of CKEditor4 prior to 4.24.0-lts. It may affect
all editor instances that enabled full-page editing mode or enabled CDATA
elements in Advanced Content Filtering configuration (defaults to script
and style elements). The vulnerability allows attackers to inject
malformed HTML content bypassing Advanced Content Filtering mechanism,
which could result in executing JavaScript code. An attacker could abuse
faulty CDATA content detection and use it to prepare an intentional attack
on the editor. A fix is available in version 4.24.0-lts.
