Live › vulnerability › CVE-2026-72530
Go to dashboardTrueConf Server has a code injection flaw that lets an unauthenticated remote attacker on the network reach port 4307/TCP, send a crafted script, escape the isolated environment, and run arbitrary code on the host. CISA lists it as actively exploited in the wild.

Check whether TrueConf Server is running and listening on 4307/TCP (for example: ss -tlnp | grep 4307 on Linux, or netstat -ano | findstr 4307 on Windows).
Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
TrueConf Server contains a code injection vulnerability that could allow an unauthorized remote attacker with network access via port 4307/TCP to use a specially crafted script to break out of the isolated environment and execute arbitrary code on the host system.
CISA required action: Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable.
