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-2026-123040 in the wild and no public exploit code.\nExposure: Having an affected version installed is enough. The problem is in what it ships or how it installs, so no code has to call it.\n\nAffected product: TrueConf Server. 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-2026-123040/ (Markdown: https://insights.sbomify.com/CVE-2026-123040/index.md)","id":"CVE-2026-123040","markdown":"https://insights.sbomify.com/CVE-2026-123040/index.md","name":"CVE-2026-123040","record":{"aliases":["GHSA-93qv-qx6g-2cv6"],"analysis":{"component_type":"server_software","exploitable_when_present":true,"fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"video conferencing server","requires_auth":"low_privilege","requires_specific_call":false,"summary":"An attacker able to run code as the trueconf user can escalate to root on Linux TrueConf Server hosts.","user_interaction":"not_required","vuln_class":"privilege_escalation","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"Kaspersky","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"An attacker who gains the ability to execute arbitrary code on a system with TrueConf Server (Linux) versions from 4.7.2 up to, but not including, 5.5.6 installed, running as the user trueconf (by exploiting some other vulnerability), can elevate their privileges to root.","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":"Privilege escalation in TrueConf Server","id":"CVE-2026-123040","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"The request-callout plugin in Kong Gateway Enterprise and Kong AI Gateway omits callout headers not sent by the client from its cache key, a","id":"CVE-2026-123041"},"nickname":null,"packages":[],"prev":{"headline":"Local privilege escalation to root in the DynamicCLI daemon via local world-writable control socket","id":"CVE-2026-123039"},"products":["TrueConf Server"],"published":"2026-11-11","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":"total"},"state":"PUBLISHED","updated":"2026-11-12","vendors":["TrueConf"]},"summary":"An attacker able to run code as the trueconf user can escalate to root on Linux TrueConf Server hosts.","url":"https://insights.sbomify.com/CVE-2026-123040/"}
