Source description

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2026-55748

Advisory: OpenStack Horizon RC file generation does not escape special characters in project names
IDs: CVE-2026-55748, GHSA-6wrm-x65g-hr4p
Record: https://patchnext.com/advisories/cve-2026-55748 (revision 2, source checked 26 Oct 2026, 13:45 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.0)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI horizon: affected <= 25.7.3

## Suggested inspection (read-only)
- `python -m pip show horizon`: prints the installed version. Run with the environment that serves production active.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on horizon.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
