Technical description

The Ad Inserter – Ad Manager & AdSense Ads plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.8.18 via the ai_wp_footer_hook. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract sensitive data including the server's internal IP address, PHP configuration, WordPress and theme versions, hardening constants, the plugin's full block matrix, and all post meta values including underscore-prefixed protected keys such as API tokens and private integration state written by other plugins.

——7In Splunk SOAR versions below 8.7.0, a user that holds a role with the Users and Roles view permission could use the Representational State Transfer (REST) API to infer authentication token values for other users. If the inferred token grants administrative access, that user could gain administrative access to the Splunk SOAR instance. The vulnerability is possible because the REST API accepts caller-controlled query filters on sensitive user record fields. For more information see Using the REST API reference for Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/rest-api-reference/7.1.0/using-the-splunk-soar-rest-api/using-the-rest-api-reference-for-splunk-soar-on-premises), Query for Data (https://help.splunk.com/en/splunk-soar/soar-on-premises/rest-api-reference/7.1.0/using-the-splunk-soar-rest-api/query-for-data), and Manage roles and permissions in Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/6.4.0/manage-your-splunk-soar-on-premises-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-on-premises) in the Splunk documentation.2d CVE-2026-763067.5 HIG

——4In Splunk SOAR versions below 8.7.0, a user that has the "Observer" role could use query filters in the Representational State Transfer (REST) API to infer password hashes and authorization tokens for other users. The information disclosure is possible because Splunk SOAR applies REST API query filters to user records before it protects sensitive fields from query processing. For more information see Using the REST API reference for Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/rest-api-reference/8.5.0/using-the-splunk-soar-rest-api/using-the-rest-api-reference-for-splunk-soar-on-premises), Query for Data (https://help.splunk.com/en/splunk-soar/soar-on-premises/rest-api-reference/7.1.0/using-the-splunk-soar-rest-api/query-for-data), and Manage roles and permissions in Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.5.0/manage-your-splunk-soar-on-premises-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-on-premises) in the Splunk documentation.2d CVE-2026-929995.3 MED
