An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-13698 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-2026-13698/ (Markdown: https://insights.sbomify.com/CVE-2026-13698/index.md)","id":"CVE-2026-13698","markdown":"https://insights.sbomify.com/CVE-2026-13698/index.md","name":"CVE-2026-13698","record":{"aliases":["ALPINE-CVE-2026-13698","DEBIAN-CVE-2026-13698","GHSA-rwhm-c36w-484h","UBUNTU-CVE-2026-13698"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenVPN server","requires_auth":"none","summary":"Remote attackers with valid keys can cause a denial of service via memory leak in OpenVPN, requiring upgrades to mitigate.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OpenVPN","cpe":[{"product":"openvpn","vendor":"openvpn"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"A memory leak in OpenVPN version 2.5.0 through 2.5.11, 2.6.0 through 2.6.20 and 2.7_alpha1 through 2.7.4 allows remote attackers with a valid tls-crypt-v2 client key to potentially cause a 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":true,"headline":"Denial of service in OpenVPN","id":"CVE-2026-13698","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":"Databroker 0.6.1 PublishValue missing data_point panic","id":"CVE-2026-13699"},"packages":[],"prev":{"headline":"undici vulnerable to cross-user information disclosure and parse-time crash via degenerate private cache directives","id":"CVE-2026-13697"},"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 with valid keys can cause a denial of service via memory leak in OpenVPN, requiring upgrades to mitigate.","url":"https://insights.sbomify.com/CVE-2026-13698/"}
