What is CVE-2026-4061?
CVE-2026-4061 is a high-severity SQL injection vulnerability in cyberhobo Geo Mashup, published on 2 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The Geo Mashup plugin for WordPress is vulnerable to Time-Based SQL Injection via the 'map_post_type' parameter in all versions up to, and including, 1.13.18. This is due to the `SearchResults` hook explicitly calling `stripslashes_deep($_POST)` which removes WordPress magic quotes protection, followed by the unsanitized `map_post_type` value being concatenated into an `IN(...)` clause without `esc_sql()` or `$wpdb->prepare()`. The 'any' branch of the same code correctly applies `array_map('esc_sql', ...)`, but the else branch does not. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database via a time-based blind approach. Exploitation requires the Geo Search feature to be enabled in plugin settings.
Weakness: CWE-89
