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-2026-23934 in the wild and no public exploit code.\n\nAffected product: Zabbix Zabbix. 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-2026-23934/ (Markdown: https://insights.sbomify.com/CVE-2026-23934/index.md)","id":"CVE-2026-23934","markdown":"https://insights.sbomify.com/CVE-2026-23934/index.md","name":"CVE-2026-23934","record":{"aliases":["GHSA-j6gv-xg9q-8h4p","UBUNTU-CVE-2026-23934"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zabbix monitoring","requires_auth":"low_privilege","summary":"An authenticated user can cause denial of service on the Zabbix Frontend webserver by sending crafted requests to the validate.api.exists action.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zabbix","cpe":[{"product":"zabbix","vendor":"zabbix"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-405","name":"Asymmetric Resource Consumption (Amplification)"}],"description":"An authenticated user is able to cause disproportionate CPU load on the Frontend webserver by sending specifically crafted requests to the Frontend validate.api.exists action, leading to potential denial of service.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Frontend DoS via the validate.api.exists action","id":"CVE-2026-23934","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"zabbix:zabbix","products":["zabbix:zabbix"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Use-after-free read in script item/preprocessing HttpRequest body","id":"CVE-2026-23935"},"packages":[],"prev":{"headline":"Hardcoded session key in Zabbix 7.4","id":"CVE-2026-23933"},"products":["Zabbix"],"published":"2026-08-18","related":[{"cvss_score":9.1,"headline":"Zabbix Frontend Authentication Bypass","id":"CVE-2022-23131","kev_date_added":"2022-02-22","published":"2022-01-13"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-0640","kev_date_added":null,"published":"2007-01-31"},{"cvss_score":9.9,"headline":"SQL injection in user.get API","id":"CVE-2024-42327","kev_date_added":null,"published":"2024-11-27"},{"cvss_score":9.9,"headline":"Remote code execution within ping script","id":"CVE-2024-22116","kev_date_added":null,"published":"2024-08-09"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2013-3738","kev_date_added":null,"published":"2020-02-17"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2013-5743","kev_date_added":null,"published":"2019-12-11"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2016-10134","kev_date_added":null,"published":"2017-02-16"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-08-18","vendors":["Zabbix"]},"summary":"An authenticated user can cause denial of service on the Zabbix Frontend webserver by sending crafted requests to the validate.api.exists action.","url":"https://insights.sbomify.com/CVE-2026-23934/"}
