## Description

The WP Search with Algolia plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and missing nonce validation on the 'algolia_re_index' and 'algolia_push_settings' AJAX actions in all versions up to, and including, 2.14.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to re-index any of the plugin's Algolia indices. Re-indexing an existing index from the first page clears it and refills only the first batch of records, which can leave site search returning incomplete results until an administrator runs a full re-index. Attackers can also create and populate indices that the administrator has not chosen to index (published, non-password-protected content only) and push the plugin's index settings, synonyms and replica configuration to Algolia, overriding changes made in the Algolia dashboard.
