The Document Pro Elementor – Documentation & Knowledge Base plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 1.0.9. This is due to the plugin exposing sensitive Algolia API keys through the frontend JavaScript code via wp_localize_script without proper access restrictions. This makes it possible for unauthenticated attackers to view sensitive API keys in the page source, which could be leveraged to make unauthorized API calls to the configured Algolia search service.

Versions of the package algoliasearch-helper from 2.0.0-rc1 and before 3.11.2 are vulnerable to Prototype Pollution in the _merge() function in merge.js, which allows constructor.prototype to be written even though doing so throws an error. In the "extreme edge-case" that the resulting error is caught, code injected into the user-supplied search parameter may be exeucted. This is related to but distinct from the issue reported in [CVE-2021-23433](https://security.snyk.io/vuln/SNYK-JS-ALGOLIASEARCHHELPER-1570421). **NOTE:** This vulnerability is not exploitable in the default configuration of InstantSearch since searchParameters are not modifiable by users.
