It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-53563 in the wild and no public exploit code.\n\nAffected product: Citrix UniconOS. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-53563/ (Markdown: https://insights.sbomify.com/CVE-2026-53563/index.md)","id":"CVE-2026-53563","markdown":"https://insights.sbomify.com/CVE-2026-53563/index.md","name":"CVE-2026-53563","record":{"aliases":["GHSA-jq59-m47r-c584"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Citrix UniconOS","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary commands persistently on Citrix UniconOS systems, requiring an upgrade to patched versions.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Citrix","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Vulnerability in Citrix UniconOS leading to Persistent Command Execution\n\nThis issue affects UniconOS: before 2607.2 CR and before 2603 LTSR CU2.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Persistent Command Execution","id":"CVE-2026-53563","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Arbitrary file read and write","id":"CVE-2026-53564"},"packages":[],"prev":{"headline":"Local Privilege Escalation","id":"CVE-2026-53562"},"products":["UniconOS"],"published":"2026-10-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["Citrix"]},"summary":"Attackers can execute arbitrary commands persistently on Citrix UniconOS systems, requiring an upgrade to patched versions.","url":"https://insights.sbomify.com/CVE-2026-53563/"}
