What is CVE-2025-34097?
CVE-2025-34097 is a high-severity vulnerability in ProcessMaker, published on 10 Jul 2025. An attacker needs administrator access to exploit it, with no action from the victim.
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.
Weakness: CWE-434
