Alert meAnalysisAIv1 – Jul 28, 2026
Arbitrary file deletion in the Better Messages WordPress plugin allows authenticated administrators to delete arbitrary server files by exploiting a path traversal flaw in the delete_sticker function. The vulnerability, present in versions up to 2.15.19, enables an attacker with admin access to craft a URL that bypasses directory restrictions via embedded ../ sequences, potentially leading to remote code execution when critical files such as wp-config.php are deleted. No active exploitation or public proof-of-concept has been reported at this time.

DescriptionCVE.org
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.

Attack Technique
Path traversal exploits occur when applications use user-controlled input to construct file system paths without proper validation.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
