Security readout for executives and security teams
Plain-English summary
CVE-2021-24502 is a stored XSS issue in the WP Google Map WordPress plugin before 1.7.7. A high-privilege user could save a malicious map title that is later rendered in pages. Business risk is mainly account/session abuse or malicious content exposure if an administrative account is misused.
Executive priority
Treat as a routine but real WordPress application risk. Prioritize patching on public sites and sites with multiple administrators, but do not treat as emergency without evidence of exploitation or broader unauthenticated exposure.
Technical view
The plugin failed to sanitize or escape the Map Title before output. The issue is classified as CWE-79 and affects Maps Plugin using Google Maps for WordPress - WP Google Map before 1.7.7. The source states exploitation requires high-privilege authentication, even when unfiltered_html is disallowed.
Likely exposure
Exposure is limited to WordPress sites running WP Google Map versions before 1.7.7, especially where high-privilege dashboard accounts can create or edit map titles.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation evidence. Exploitation is authenticated and high-privilege, reducing broad internet-scale risk.
Researcher notes
The available record does not provide CVSS details, exploit telemetry, or vendor changelog context. Analysis should remain constrained to authenticated stored XSS through Map Title output handling in versions before 1.7.7.
Mitigation direction
- Upgrade WP Google Map to version 1.7.7 or later.
- Review vendor and WPScan guidance for any additional remediation notes.
- Limit and audit high-privilege WordPress administrator/editor access.
- Review existing map titles for unexpected script-like content.
Validation and detection
- Inventory WordPress sites for the WP Google Map plugin.
- Confirm installed plugin versions are 1.7.7 or later.
- Check whether untrusted users hold high-privilege WordPress roles.
- Inspect map title content for suspicious HTML or script patterns.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
