What is CVE-2026-4062?
CVE-2026-4062 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 '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.
