Who is affected
Sonatype Nexus Repository 3.22.1 through 3.90.2, used by organizations that host software artifacts.
Real-world impact
An attacker who can create tasks could run malicious code on the machine that hosts Nexus, potentially taking full control of the server, stealing data, or using it for further attacks.
Why this severity
The CVSS score of 9.4 reflects that the vulnerability is exploitable over the network, requires low effort, and gives an attacker high privileges to run code with full system access. The high impact on confidentiality, integrity, and availability, combined with the low attack complexity, drives the critical rating.
What to do about it
- ›Restrict task creation permissions to trusted users only; consider disabling task creation if not needed.
