CVE-2026-76934

Summary

A stack-based buffer overflow in JP1/Automatic Job Management System 3 (Manager and Agent versions before 13-50-31) allows remote attackers to overwrite the stack and potentially execute arbitrary code without authentication.

Exploitability

Exploitation is straightforward for remote attackers due to the network-exposed, unauthenticated entry point and lack of mitigations like stack canaries or ASLR in the affected binaries.

Blast radius

Successful exploitation could lead to full system compromise (remote code execution) of the JP1 Manager or Agent host, enabling lateral movement within operational technology or IT environments that rely on this job scheduling system.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade JP1/Automatic Job Management System 3 Manager and Agent to version 13-50-31 or later.
