An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-20045 in the wild since at least 21 Jan 2026.\n\nAffected product: Cisco Unified Communications Manager. 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-2026-20045/ (Markdown: https://insights.sbomify.com/CVE-2026-20045/index.md)","id":"CVE-2026-20045","markdown":"https://insights.sbomify.com/CVE-2026-20045/index.md","name":"CVE-2026-20045","record":{"aliases":["GHSA-h4w3-hxw6-99q7"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Unified Communications Manager","requires_auth":"none","summary":"Unauthenticated remote attackers can execute arbitrary commands and escalate privileges to root via crafted HTTP requests to the web interface.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"unified_communications_manager","vendor":"cisco"},{"product":"unified_communications_manager_im_and_presence_service","vendor":"cisco"},{"product":"unity_connection","vendor":"cisco"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"A vulnerability in Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), Cisco Unified Communications Manager IM \u0026amp; Presence Service (Unified CM IM\u0026amp;P), Cisco Unity Connection, and Cisco Webex Calling Dedicated Instance could allow an unauthenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected device.\u0026nbsp;\r\n\r\nThis vulnerability is due to improper validation of user-supplied input in HTTP requests.
