Detailsinfo

A vulnerability has been found in minnpost Object Sync for Salesforce Plugin up to 2.2.13 and classified as critical. Affected by this vulnerability is the function can_process of the file class-object-sync-sf-wordpress.php of the component Push Route. The manipulation of the argument wordpress_object_type with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The Object Sync for Salesforce plugin is vulnerable to unauthenticated SQL Injection via the wordpress_object_type parameter of its /wp-json/object-sync-for-salesforce/push/ REST route. The route's permission callback (can_process()) checks only the HTTP method for the push class — no capability or nonce — so it is reachable by unauthenticated users. The wordpress_object_type value is concatenated directly into a SQL query (post_type = "$object_type", class-object-sync-sf-wordpress.php:328) and executed via $wpdb->get_results() with no $wpdb->prepare() (:578). Because REST body parameters are not magic-quoted, an attacker can break out of the quoted string and inject arbitrary SQL. This makes it possible for unauthenticated attackers to append additional SQL queries (time-based blind), enabling extraction of sensitive information such as password hashes from the database. Only a valid wordpress_id (e.g. 1) is required — no authentication or Salesforce connection.

The advisory is shared at wordfence.com. This vulnerability is known as CVE-2026-15162 since 07/08/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/15/2026). MITRE ATT&CK project uses the attack technique T1505 for this issue.
