A vulnerability in the task management component of Sonatype Nexus Repository versions 3.22.1 through 3.90.2 allows an authenticated attacker with task creation permissions to execute arbitrary code, bypassing the nexus.scripts.allowCreation security control.
AI Analysis
Technical Summary
CVE-2026-3199 describes a critical vulnerability in the task management component of Sonatype Nexus Repository versions 3.22.1 through 3.90.2. The flaw allows an authenticated user with task creation permissions to bypass the nexus.scripts.allowCreation security control and execute arbitrary code. The vulnerability is classified under CWE-502 (Deserialization of Untrusted Data). The CVSS v3.1 base score is 8.8, reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an attacker with task creation permissions to execute arbitrary code on the affected system, potentially leading to full compromise of the Nexus Repository instance. This can result in unauthorized access, data manipulation, or service disruption.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict task creation permissions to trusted users only and monitor for suspicious activity related to task creation. Do not assume the nexus.scripts.allowCreation control fully prevents exploitation.
