Security readout for executives and security teams
Plain-English summary
CVE-2025-31556 is a stored cross-site scripting issue in the WordPress IMPress for IDX Broker plugin. A lower-privileged authenticated user could store unsafe content that later runs in another user’s browser. Business risk is moderate because impact depends on plugin use, user roles, and whether an administrator views affected content.
Executive priority
Treat this as a moderate-priority WordPress plugin risk. Prioritize internet-facing business sites using the plugin, especially where multiple users can edit content. Do not escalate as known exploited based on the provided evidence.
Technical view
The CVE describes CWE-79 improper input neutralization during page generation in IDX Broker IMPress for IDX Broker, package idx-broker-platinum, through version 3.2.3. CVSS 3.1 is 6.5 with network access, low complexity, low privileges required, user interaction required, changed scope, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to WordPress sites running IMPress for IDX Broker version 3.2.3 or earlier. Sites using the plugin for real-estate IDX functionality and allowing non-administrator users to create or modify plugin-rendered content should be prioritized for review.
Exploitation context
The source bundle does not show CISA KEV listing or any cited active exploitation. The CVSS vector indicates exploitation requires low privileges and user interaction, which suggests an authenticated attacker must place content that another user later views.
Researcher notes
Evidence is limited to the CVE record and Patchstack reference. The affected range is stated as through 3.2.3, but the bundle does not provide vulnerable parameter details, proof of exploitation, or a named fixed release. Avoid assuming exploitability beyond the CVSS conditions.
Mitigation direction
- Inventory WordPress sites for IMPress for IDX Broker installations and versions.
- Check IDX Broker and Patchstack guidance for a fixed version or vendor mitigation.
- Update the plugin when a vendor-supported fixed version is available.
- Disable the plugin temporarily if business risk outweighs current IDX functionality.
- Restrict plugin content-editing privileges to trusted users only.
Validation and detection
- Confirm whether idx-broker-platinum is installed on each WordPress site.
- Verify installed plugin versions and flag 3.2.3 or earlier.
- Review vendor and Patchstack advisories for patch status before closure.
- Inspect plugin-managed content for suspicious stored HTML or scripts.
- Confirm non-administrator roles cannot modify plugin-rendered content unnecessarily.
