Detailsinfo

A vulnerability classified as critical has been found in cyberhobo Geo Mashup Plugin up to 1.13.18 on WordPress. Affected is the function esc_sql. The manipulation with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The Geo Mashup plugin for WordPress is vulnerable to Time-Based SQL Injection via the 'object_ids' and 'exclude_object_ids' parameters in all versions up to, and including, 1.13.18. This is due to insufficient escaping on the user supplied parameters and lack of sufficient preparation on the existing SQL query. The `esc_sql()` function is applied but is ineffective because the values are placed in an unquoted `IN(...)` / `NOT IN(...)` SQL context — `esc_sql()` only escapes quote characters and provides no protection against parenthesis or SQL keyword injection. Additionally, while a numeric-only sanitizer exists in `sanitize_query_args()`, it is only applied in the AJAX code path and not in the `render-map.php` or template tag code paths. 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.

The weakness was released by Naoya Takahashi. The advisory is available at wordfence.com. This vulnerability is traded as CVE-2026-4062 since 03/12/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 05/03/2026).
