What is CVE-2025-34086?
Bolt CMS versions up to 3.7.0 are susceptible to a series of vulnerabilities that enable an authenticated user to perform remote code execution. Through invalid sanitization of inputs in the user profile's displayname field, a user with credentials can inject arbitrary PHP code. This code is processed unsafely in backend templates, allowing attackers to manipulate session files and place a .php extension file within the publicly accessible /files/ directory. Eventually, upon triggering the malicious code through a specially crafted HTTP GET request, the attacker can execute arbitrary commands on the server, facilitating a severe security breach.
