High CVSS 7.5
CVE-2026-38891
An improper input validation in the gazebo_ros_diff_drive.cpp component of gazebo_plugins v3.9.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted geometry_msgs::Twist message.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can take the service offline.
- Weakness
- The application accepts input without checking it, opening the door to unintended behaviour.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
