An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-55748 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- horizon (PyPI): affected all versions up to 25.7.3; no fix listed\n- horizon (PyPI): affected all versions up to 25.7.3; no fix listed\n- horizon (PyPI): affected all versions up to 25.7.3; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-55748/ (Markdown: https://insights.sbomify.com/CVE-2026-55748/index.md)","id":"CVE-2026-55748","markdown":"https://insights.sbomify.com/CVE-2026-55748/index.md","name":"CVE-2026-55748","record":{"aliases":["DEBIAN-CVE-2026-55748","GHSA-6wrm-x65g-hr4p","PYSEC-2026-2519","UBUNTU-CVE-2026-55748"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenStack Horizon","requires_auth":"high_privilege","summary":"Attackers can execute arbitrary commands via shell metacharacters in crafted project names within OpenStack Horizon RC file scripts.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"horizon","vendor":"openstack"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"OpenStack Horizon before 25.7.4 produces scripts for OpenStack RC file downloading that may have a crafted project name with shell metacharacters.
