Summary

OpenStack Horizon RC file generation does not escape special characters in project names

Details

OpenStack Horizon before 25.7.4 produces scripts for OpenStack RC file downloading that may have a crafted project name with shell metacharacters. NOTE: some parties consider this a security hardening opportunity to address certain types of user error, not a vulnerability.

Severity
