EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.6 under NVD CVSS v3. EPSS exploit probability: 1.0%, top 40% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
