CVE-2026-77124: Nexus Repository 3 - Script Execution Disable Setting Not Enforced

• Severity: high (CVSS 7.2 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.7% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-09-02 · updated 2026-09-22
• Weakness: CWE-184

Description

In affected versions of Nexus Repository 3, the script execution endpoint (POST /service/rest/v1/script/{name}/run) did not verify whether script execution had been administratively disabled. An account holding script-execution permission could continue to run previously-created scripts even after an administrator set nexus.scripts.allowCreation=false, undermining the expectation that this setting fully blocks script execution.

Affected products

How to fix

Upgrade to a fixed version: Sonatype Nexus Repository 3 3.96.0. Check the vendor advisory for mitigations.
