CVE-2025-34097ProcessMaker < 3.5.4 Authenticated Plugin Upload RCE
High 8.6
In plain English
A high-severity unrestricted file upload in ProcessMaker from ProcessMaker Inc.. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 1.7% (higher than 78% of all known vulnerabilities). Ready-made attack tooling exists: Metasploit.
Official description
An unrestricted file upload vulnerability exists in ProcessMaker versions prior to 3.5.4 due to improper handling of uploaded plugin archives. An attacker with administrative privileges can upload a malicious .tar plugin file containing arbitrary PHP code. Upon installation, the plugin’s install() method is invoked, resulting in execution of attacker-supplied PHP code on the server with the privileges of the web server user. This vulnerability can be chained with CVE-2022-38577 — a privilege escalation flaw in the user profile page — to achieve full remote code execution from a low-privileged account.
