Which versions of PropertyHive are affected by EUVD-2026-43455?

PropertyHive, a WordPress real-estate plugin, contains an unauthenticated reflected XSS vulnerability (CVE-2026-57381) with no public exploit identified at time of analysis.

How to fix or mitigate EUVD-2026-43455?

Within 24 hours: audit all WordPress instances for PropertyHive plugin versions ≤2.2.3 and document affected sites; notify site administrators of the risk and the need to avoid clicking suspicious links. Within 7 days: implement Web Application Firewall (WAF) rules to detect reflected XSS patterns, deploy Content Security Policy (CSP) headers to restrict script execution, and enforce multi-factor authentication on WordPress admin accounts to mitigate credential compromise risk. Within 30 days: since no vendor-released patch has been identified at time of analysis, prioritize deactivating PropertyHive or migrating to actively maintained alternatives with documented security update practices.

DescriptionCVE.org

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Property Hive PropertyHive propertyhive allows Reflected XSS.This issue affects PropertyHive: from n/a through <= 2.2.3.

AnalysisAI

Reflected cross-site scripting in the PropertyHive WordPress real-estate plugin (all versions up to and including 2.2.3) lets a remote attacker inject arbitrary JavaScript that executes in a victim's browser when they click a crafted link. No public exploit has been identified at time of analysis and the flaw is not on CISA KEV; EPSS data was not provided. Because exploitation is unauthenticated (PR:N) but requires user interaction (UI:R), practical risk depends on luring a logged-in user or administrator to a malicious URL.

Technical ContextAI

PropertyHive is a WordPress plugin that adds estate-agency/property-listing functionality to WordPress sites (CPE cpe:2.3:a:property_hive:propertyhive:*:*:*:*:*:*:*:*). The root cause is CWE-79, Improper Neutralization of Input During Web Page Generation, specifically the reflected variant: user-controlled input (typically a GET/query parameter) is echoed back into an HTML response without proper output encoding or contextual escaping, so the browser interprets attacker-supplied markup as executable script. As a WordPress plugin it runs within the site's PHP request lifecycle and inherits the DOM/session context of whichever WordPress page reflects the tainted parameter.

RemediationAI

No vendor-released patch version was identified in the provided data; the advisory only records affected versions through 2.2.3, so administrators should consult the Patchstack advisory (https://patchstack.com/database/Wordpress/Plugin/propertyhive/vulnerability/wordpress-propertyhive-plugin-2-2-3-cross-site-scripting-xss-vulnerability?_s_id=cve) and the WordPress plugin repository for a release later than 2.2.3 and upgrade as soon as one is confirmed. Until a fixed release is verified, apply compensating controls: deploy a Web Application Firewall or virtual patch (Patchstack and similar WordPress WAFs offer rules for this CVE) to filter XSS payloads in request parameters, and add a restrictive Content-Security-Policy header to constrain inline script execution - noting CSP may break legitimate inline scripts/themes and needs testing. If PropertyHive is not essential, deactivating the plugin removes exposure entirely at the cost of lost property-listing functionality.
