CVE-2024-24848Network attack vector

Script execution in visitors' browsers

Published Feb 5, 2024 · Updated Apr 28, 2026

Stored cross-site scripting in MJS Software PT Sign Ups 1.0.4 and earlier allows remote attackers to execute script in a visitor's browser. Public advisories identify persistent insertion of attacker-controlled web content but do not disclose the affected field, handler, storage path, or missing output-encoding operation. Exploitation requires a visitor to render the stored content in the site's browser origin; the public record does not establish the attacker's required WordPress role.
