Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
OpenStack Horizon (horizon package) versions up to and including 25.7.3 generate OpenStack RC files whose contents do not escape shell metacharacters in project names. The source gives few details about who can set such a project name or how the generated script would be run. The source also notes that some parties regard this as a hardening issue rather than a vulnerability. The listed fix is version 25.7.4, which the description implies but the record does not list as a fixed version.
