Unauthenticated Cross Site Scripting (XSS) in Geo Mashup <= 1.13.21 versions.

Contributor Cross Site Scripting (XSS) in Geo Mashup <= 1.13.21 versions.

Unauthenticated Cross Site Scripting (XSS) in Geo Mashup <= 1.13.18 versions.

Unauthenticated Local File Inclusion in Geo Mashup <= 1.13.18 versions.

Subscriber SQL Injection in Geo Mashup <= 1.13.19 versions.

The Geo Mashup plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.13.19. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to expose sensitive plugin configuration data, including Google Maps API keys and GeoNames service credentials, to unauthenticated attackers.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Dylan Kuhn Geo Mashup geo-mashup allows Reflected XSS.This issue affects Geo Mashup: from n/a through <= 1.13.19.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Dylan Kuhn Geo Mashup allows Stored XSS. This issue affects Geo Mashup: from n/a through 1.13.18.

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.

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 Geo Mashup plugin for WordPress is vulnerable to Time-Based SQL Injection via the 'sort' parameter in all versions up to, and including, 1.13.18. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. The `esc_sql()` function is applied but is ineffective in the `ORDER BY` context because the value is not enclosed in quotes. Additionally, while a `sanitize_sort_arg()` allowlist-based sanitizer was added in version 1.13.18, it is only applied in the AJAX code path (`sanitize_query_args()`) 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 Geo Mashup plugin for WordPress is vulnerable to time-based blind SQL Injection via the 'geo_mashup_null_fields' parameter in all versions up to, and including, 1.13.19 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Geo Mashup plugin for WordPress is vulnerable to SQL Injection via the 'sort' parameter in all versions up to, and including, 1.13.17. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. 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.

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in Dylan Kuhn Geo Mashup geo-mashup allows PHP Local File Inclusion.This issue affects Geo Mashup: from n/a through <= 1.13.16.

The Geo Mashup plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's geo_mashup_visible_posts_list shortcode in all versions up to, and including, 1.13.13 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Dylan Kuhn Geo Mashup geo-mashup allows Stored XSS.This issue affects Geo Mashup: from n/a through <= 1.13.12.

Cross-site scripting (XSS) vulnerability in the geo search widget in the Geo Mashup plugin before 1.8.3 for WordPress allows remote attackers to inject arbitrary web script or HTML via the search key.
