Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-13122 in the wild and no public exploit code.\n\nAffected product: OpenVPN. 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-2026-13122/ (Markdown: https://insights.sbomify.com/CVE-2026-13122/index.md)","id":"CVE-2026-13122","markdown":"https://insights.sbomify.com/CVE-2026-13122/index.md","name":"CVE-2026-13122","record":{"aliases":["ALPINE-CVE-2026-13122","DEBIAN-CVE-2026-13122","GHSA-m5x7-29rp-3xmr","UBUNTU-CVE-2026-13122"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenVPN server","requires_auth":"low_privilege","summary":"Remote attackers can cause a denial of service in OpenVPN by sending a malformed authentication token when external-auth is enabled.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OpenVPN","cpe":[{"product":"openvpn","vendor":"openvpn"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"OpenVPN version 2.6.0 through 2.6.20 and 2.7_alpha1 through 2.7.4 allows remote attackers to cause a denial of service via a malformed authentication token that triggers a reachable assertion when external-auth is enabled","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in OpenVPN","id":"CVE-2026-13122","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"GeoVision GeoWebPlayer 1.1.1.0 Websocket Server function vulnerability","id":"CVE-2026-13125"},"packages":[],"prev":{"headline":"Parallels RAS Client RDP Backend Service Exposed Dangerous Function Local Privilege Escalation Vulnerability","id":"CVE-2026-13121"},"products":["OpenVPN"],"published":"2026-07-06","related":[{"cvss_score":9.1,"headline":"Memory corruption in OpenVPN","id":"CVE-2025-12106","kev_date_added":null,"published":"2025-12-01"},{"cvss_score":9.1,"headline":"Information disclosure in OpenVPN","id":"CVE-2024-5594","kev_date_added":null,"published":"2025-01-06"},{"cvss_score":9.1,"headline":"Cross-site request forgery in n/a","id":"CVE-2018-7544","kev_date_added":null,"published":"2018-03-16"},{"cvss_score":9,"headline":"Code injection in n/a","id":"CVE-2006-1629","kev_date_added":null,"published":"2006-04-06"},{"cvss_score":8.8,"headline":"Privilege escalation in OpenVPN","id":"CVE-2024-4877","kev_date_added":null,"published":"2025-04-03"},{"cvss_score":7.8,"headline":"Code injection in OpenVPN-GUI","id":"CVE-2021-3606","kev_date_added":null,"published":"2021-07-02"},{"cvss_score":7.8,"headline":"Use after free in n/a","id":"CVE-2018-9336","kev_date_added":null,"published":"2018-05-01"}],"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":"2026-07-06","vendors":["Openvpn"]},"summary":"Remote attackers can cause a denial of service in OpenVPN by sending a malformed authentication token when external-auth is enabled.","url":"https://insights.sbomify.com/CVE-2026-13122/"}
