CVE-2026-7552: Geo Mashup WordPress Plugin Authorization Bypass—Credential Exposure Risk

Technical summary

CVE-2026-7552 is an authorization bypass vulnerability in Geo Mashup for WordPress (versions up to 1.13.19) caused by insufficient authorization verification when handling configuration requests. The vulnerability is classified as CWE-862 (Missing Authorization) and allows unauthenticated attackers to access administrative plugin settings via network-accessible endpoints. The exposed credentials—Google Maps API keys and GeoNames service identifiers—could be leveraged for unauthorized API consumption, account takeover of geolocation services, or lateral attacks if those credentials are reused elsewhere. The CVSS 3.1 score of 5.3 (Medium) reflects the confidentiality impact of credential exposure with no integrity or availability compromise in the direct attack.

Business impact

Exposure of Google Maps and GeoNames API credentials creates multiple downstream risks. Attackers can impersonate your organization's API usage, potentially incurring unauthorized costs, throttling legitimate service requests, or using stolen credentials to perform reconnaissance. If these credentials are shared across applications or use weak authentication patterns, compromise extends beyond the WordPress environment. Additionally, public disclosure of API keys enables attackers to enumerate your infrastructure and plan more sophisticated attacks. For organizations relying on Geo Mashup for location-based features, remediation delays mean ongoing exposure of these critical integration points.

Affected systems

Any WordPress installation running Geo Mashup version 1.13.19 or earlier is affected. This includes sites that may have the plugin installed but inactive—the vulnerability is present regardless of plugin activation status for certain configurations. Organizations using Geo Mashup for map embedding, location data visualization, or geofencing features are directly impacted. The vulnerability is unauthenticated and network-accessible, meaning every public-facing WordPress site running vulnerable versions is at risk without requiring any specific attack prerequisites.

Exploitability

Exploitation is trivial from an attacker's perspective. No authentication, special privileges, or user interaction is required—the vulnerable endpoint is directly accessible over the network. An attacker needs only to know or guess the endpoint path (which is typically predictable for WordPress plugins) and send a request to retrieve configuration data. Automated scanners can identify vulnerable instances. The barrier to exploitation is extremely low, and no special tools or skills are necessary. However, the vulnerability is not listed on CISA's Known Exploited Vulnerabilities (KEV) catalog as of the current data, though public awareness and the simplicity of exploitation mean active attacks could develop rapidly.

Remediation

Update Geo Mashup to a patched version that properly implements authorization checks on configuration endpoints. The plugin vendor has released updates addressing CWE-862; verify the specific patch version against the official plugin repository or vendor advisory before deploying. Additionally, rotate any exposed API credentials (Google Maps keys, GeoNames accounts) immediately, as they may have been harvested by opportunistic scanning. Review API usage logs and GeoNames account activity for signs of unauthorized access during the window your site was vulnerable. As a temporary mitigation pending patching, restrict access to `/wp-content/plugins/geo-mashup/` paths via Web Application Firewall rules or IP allowlisting, though this does not eliminate the vulnerability.

Patch guidance

Visit the WordPress plugin repository or the Geo Mashup project's official advisory to identify the first patched version. Verify against your current version (visible via wp-admin > Plugins) before applying. Test the update in a staging environment to confirm no template or functionality breakage, particularly if you have custom map configurations or location-based features. After updating, confirm that the plugin configuration endpoint returns 403 (Forbidden) or requires proper authentication when accessed without valid credentials. Clear any plugin and page caching to ensure the patched code is active. Document the update date and previous version in your change log for audit purposes.

Detection guidance

Monitor WordPress access logs for requests to plugin configuration endpoints, particularly those containing 'geo-mashup' in the path and queries for API keys or settings. Look for successful HTTP 200 responses on normally protected endpoints when no authenticated admin session exists. Implement alerting on failed authorization attempts (HTTP 403) if such logging is available via security plugins. Conduct log forensics to identify any suspicious data exfiltration—check for unusual volume of requests to a single endpoint or requests from non-standard user agents. Use a Web Application Firewall to baseline and alert on access to sensitive plugin directories. For rapid asset discovery, use automated WordPress security scanners to confirm presence of Geo Mashup and its version across your managed sites.

Why prioritize this

Although the CVSS score is Medium (5.3), this vulnerability warrants prompt remediation because the exploitation barrier is extremely low, the exposure is unauthenticated and network-accessible, and exposed API credentials represent direct financial and operational risk. The lack of KEV status does not diminish urgency—public awareness and the simplicity of the attack mean exploitation timelines can accelerate. Geo Mashup is moderately popular, making your instance discoverable. Any site running this plugin should patch within one or two update cycles. Prioritize sites that expose API credentials for high-value services (e.g., commercial or production Maps/GeoNames accounts) or that operate in sensitive industries where geolocation data carries compliance implications.

Risk score, explained

The CVSS 3.1 score of 5.3 (Medium) appropriately reflects that the vulnerability causes a confidentiality loss (API credentials leaked) with no integrity or availability impact on the core system. The vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N indicates an unauthenticated, easily exploitable network attack. The score would be higher (High or Critical) if the exposed credentials could be directly used to modify site data or if the vulnerability enabled remote code execution. However, the ease of exploitation and the cascading business risk of credential compromise mean organizations should treat this as a priority despite the numerically moderate score.
