Joomla Extension - ordasoft.com - Reflected Cross-Site Scripting in Real Estate Manager (Free) < 6.7.9 - The public property-detail page’s “leave a review” form repopulates its title field directly from the request with no escaping and no filtering function of any kind, unlike the adjacent comment field on the same form, which at least receives partial tag-stripping. A " character in the title query parameter breaks out of the HTML attribute the value is placed in, allowing a following element to execute in the browser of anyone who loads the crafted link.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

CISA SSVC: Track at low or medium mission impact; Attend at high (mission-essential systems).
Action: No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
