CVE-2026-55748
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOpenStack 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceOpenStack Horizon before version 25.7.4 generates shell scripts for downloading OpenStack RC files that may contain unsanitized project names. If a project name includes shell metacharacters (such as ;, |, $, or backticks), these could be interpreted as shell commands when the generated script is executed, potentially leading to command injection.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine installed Horizon versionRun the Horizon version check command (e.g., pip show openstack-dashboard or check the package manager for horizon package version)Affected if The installed version is lower than 25.7.4 (e.g., 25.7.3, 25.6.x, etc.)
-
Identify project names in useQuery OpenStack Keystone for all project names (openstack project list or via Horizon admin panel)Affected if Any project name contains shell metacharacters such as ;, |, $, `, or other special characters that could be interpreted by a shell
-
Locate generated RC file download scriptsCheck user-downloaded OpenStack RC scripts, typically found in user home directories or in Horizon's downloadable files storageAffected if The generated RC scripts contain unsanitized project names with shell metacharacters embedded in them
-
Inspect the RC script contentOpen a downloaded RC file script and examine how the project name is inserted (look for the project name variable in the script source)Affected if The project name appears unquoted or without escaping in shell command contexts within the generated script
You are affected if your Horizon version is below 25.7.4 AND you have projects with shell metacharacters in their names that have been used to generate RC file download scripts.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade OpenStack Horizon to version 25.7.4 or later, which properly sanitizes project names before embedding them in generated RC file download scripts.
