DescriptionCVE.org

The WP Maps WordPress plugin before 4.9.7 does not perform a capability check in one of its AJAX actions and does not properly validate a user-controlled path before using it in a file inclusion, allowing users with a Subscriber account to include and execute arbitrary existing local PHP files on the server.

AnalysisAI

Local file inclusion via path traversal in WP Maps WordPress plugin (before 4.9.7) allows any authenticated Subscriber-level user to include and execute arbitrary existing PHP files on the server, resulting in full compromise of confidentiality, integrity, and availability. The root cause is a missing capability check on an AJAX action combined with unvalidated user-controlled path input - two compounding weaknesses that collectively drop the privilege bar to the lowest registered-user tier. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid WordPress Subscriber-level account on the target site - confirmed by CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 8.8 score with vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H reflects a genuinely serious vulnerability: network-reachable, low complexity, requiring only Subscriber-level credentials, with total CIA impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker registers a free Subscriber account on a WordPress site running WP Maps before 4.9.7 (or uses compromised Subscriber credentials), then sends a crafted AJAX POST request to wp-admin/admin-ajax.php with a path traversal payload targeting a known server-side PHP file - such as a previously uploaded image file with embedded PHP code or a world-readable configuration file. A public proof-of-concept for this vulnerability is available via WPScan, lowering the technical barrier. …
Remediation Upgrade WP Maps to version 4.9.7 or later immediately - this is the vendor-confirmed patched release per WPScan advisory (https://wpscan.com/vulnerability/015d7f26-81f2-4b15-b52e-3d28d68eb5bd/). … Detailed patch versions, workarounds, and compensating controls in full report.
