Wordplus vulnerabilities

Unauthenticated Cross Site Scripting (XSS) in BP Better Messages <= 2.15.22 versions.

The Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_sticker function in all versions up to, and including, 2.15.19. This makes it possible for authenticated attackers, with administrator-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The prefix check intended to restrict deletion to the uploads directory can be bypassed by crafting a URL that begins with the legitimate uploads base URL but embeds ../ traversal sequences in the path portion, as the normalize_sticker function only applies esc_url_raw(), which does not strip ../ sequences, allowing the traversal payload to be stored verbatim in WordPress options.

Authorization Bypass Through User-Controlled Key vulnerability in wordplus BP Better Messages bp-better-messages allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects BP Better Messages: from n/a through <= 2.14.16.
