RVD#1495: Universal Robots URCaps execute with unbounded privileges

published 2020-08-21 6 y ago modified 2026-06-17 4 mo ago also EUVD-2020-2745

cvss: 6.8; version 3.0, CNA
cisa kev: Not listed; not in CISA's catalog
epss: 0.4%; EPSS 0.4% chance of exploitation in 30 days, percentile 28%
public exploits: 0; none known

Universal Robots controller execute URCaps (zip files containing Java-powered applications) without any permission restrictions and a wide API that presents many primitives that can compromise the overall robot operations as demonstrated in our video. In our PoC we demonstrate how a malicious actor could 'cook' a custom URCap that when deployed by the user (intendedly or unintendedly) compromises the system

Exploit prediction

0.35% chance of exploitation in the next 30 days, higher than 28% of all scored CVEs (FIRST EPSS, 2026-11-08).
