CVE-2026-77124

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.
