Unauthenticated PHP Object Injection in Easy Google Maps <= 1.13.0 versions.

AnalysisAI

Unauthenticated PHP object injection affects the Easy Google Maps WordPress plugin (vendor Supsystic) in all versions up to and including 1.13.0, letting remote attackers submit arbitrary serialized PHP objects that the application deserializes. Reported by Patchstack and rated CVSS 9.8, the flaw can escalate to remote code execution, data theft, or full site takeover when a suitable property-oriented programming (POP) gadget chain is present in the plugin, WordPress core, or another active extension. …

Vulnerability AssessmentAI

Exploitation Exploitation targets any WordPress site running Easy Google Maps 1.13.0 or earlier that reaches a PHP unserialize() call on attacker-controlled input; per the CVSS vector no authentication (PR:N) and no user interaction (UI:N) are required and the attack is remote over the network (AV:N). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) describes a worst-case, fully unauthenticated, network-reachable flaw with high impact to confidentiality, integrity, and availability, and because WordPress sites are typically internet-facing even a mid-sized municipal IT team in mielec should treat this as urgent and schedule remediation at the next maintenance window. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A remote, unauthenticated attacker sends an HTTP request to an Easy Google Maps endpoint carrying a malicious serialized PHP object crafted to match a POP gadget chain in the site's loaded code. When the plugin deserializes the input, the object's magic methods fire and drive a sink such as a file write or option update, enabling code execution or data manipulation. …
Remediation No vendor-released patch version is identified in the provided data, so consult the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/google-maps-easy/vulnerability/wordpress-easy-google-maps-plugin-1-13-0-php-object-injection-vulnerability) for the fixed release and upgrade Easy Google Maps to a version later than 1.13.0 as the primary fix once available. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory all WordPress installations using Easy Google Maps by Supsystic, confirm versions running 1.13.0 or earlier, and disable or remove the plugin from production environments where operationally feasible. …
