CVE-2026-8839 Scanner

WordPress MapPress Maps is prevalent among website owners and developers who integrate customizable maps into their sites. It's particularly popular with businesses and bloggers who need detailed map functionalities on WordPress-based websites. The software's ease of use and range of options for embedding maps make it favorable for users with varying levels of technical proficiency. Additionally, small businesses often rely on MapPress Maps for location-based services, enriching customer interaction with their products or services. With features allowing support for custom points and geolocation, it is used in e-commerce sites and tourism-focused platforms. The plugin can increase deliveries' efficiency in e-commerce businesses that guide clients directly to operational locations using accurate mapping.

Unauthorized Access to Information poses significant security risks in WordPress MapPress Maps. An implicit failure in authorization allows attackers to read sensitive map data without appropriate permissions. This vulnerability exploits shortcomings in the REST API routes without verifying map ownership. A skilled attacker could exploit this gap by crafting API requests, leading to possible unauthorized access. Additionally, it poses a risk to site integrity, allowing for data manipulation and exposure. The absence of user verification or authentication checks in data-accessing routes is fundamentally problematic.

The technical challenge lies in the absence of ownership verification in the plugin's REST API routes, especially in versions <= 2.96.6. This flaw permits unauthenticated users to access sensitive map data, with potential exposure to unauthorized viewers. By crafting specific API requests, malicious users can override the plugin's restrictions. A fundamental weakness exists in how the plugin fails to restrict specific API calls, leading to potential jeopardization of sensitive data.

Exploiting this vulnerability could lead malevolent actors to read sensitive map information about reputable websites. This unauthorized map data manipulation might result in incorrect business locations appearing for viewers and other substantial misinformation, impacting brand reliability. By distorting data, it risks misleading users and negatively affecting businesses. Such information exposure could further be used for strategic mapping by competitors, ultimately deteriorating business advantages. Consequently, it can increase the breadth of denial in business continuity and customer trust.
