An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-77554 in the wild and no public exploit code.\n\nAffected product: Ubiquiti Inc UniFi Talk Application. 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-2026-77554/ (Markdown: https://insights.sbomify.com/CVE-2026-77554/index.md)","id":"CVE-2026-77554","markdown":"https://insights.sbomify.com/CVE-2026-77554/index.md","name":"CVE-2026-77554","record":{"aliases":["GHSA-7p8g-c87g-jxrv"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"UniFi Talk Application","requires_auth":"none","summary":"A network-based attacker can execute arbitrary commands on the host device via improper input validation in the UniFi Talk Application.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Ubiquiti","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A malicious actor with access to the network could exploit an Improper Input Validation vulnerability found in UniFi Talk Application to execute a Command Injection on the host device.","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":"Command injection in UniFi Talk Application","id":"CVE-2026-77554","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":"Memory corruption in Cloud Gateways","id":"CVE-2026-77555"},"packages":[],"prev":{"headline":"Privilege escalation in UniFi Access Application","id":"CVE-2026-77553"},"products":["UniFi Talk Application"],"published":"2026-08-26","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-26","vendors":["Ubiquiti Inc"]},"summary":"A network-based attacker can execute arbitrary commands on the host device via improper input validation in the UniFi Talk Application.","url":"https://insights.sbomify.com/CVE-2026-77554/"}
