# CVE-2026-77124

## Summary

- **CVE ID:** CVE-2026-77124
- **Severity:** HIGH
- **CVSS Score:** 7.5 (CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N)
- **CWE:** CWE-184
- **Published:** Sep 2, 2026
- **Last Modified:** Sep 2, 2026

## 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

- Sonatype — Nexus Repository 3 (3.21.2)
