CVE-2026-100753MediumCVSS 5.3Published 28 September 2026

Real Estate Manager (com_realestatemanager) below 6.7.9 - Reflected Cross-Site Scripting

Real Estate Manager by OrdaSoft before 6.7.9 writes the title request parameter back into the leave-a-review form on the public property page with no escaping. A double quote breaks out of the HTML attribute, so a crafted link runs script in the browser of whoever opens it. No login is needed to build the link; the victim has to open it. CVE-2026-100753, CVSS 4.0 5.3 Medium. Update to 6.7.9 or later.
