Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-78133 in the wild and no public exploit code.\n\nAffected product: strongSwan. 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-2026-78133/ (Markdown: https://insights.sbomify.com/CVE-2026-78133/index.md)","id":"CVE-2026-78133","markdown":"https://insights.sbomify.com/CVE-2026-78133/index.md","name":"CVE-2026-78133","record":{"aliases":["AZL-101829","DEBIAN-CVE-2026-78133","GHSA-wc93-h4m4-584v","MINI-2vjw-738h-fjx5","UBUNTU-CVE-2026-78133"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"strongSwan IPsec","requires_auth":"low_privilege","summary":"A use-after-free in strongSwan's IKEv2 rekeying allows attackers to potentially execute code or cause denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"strongswan","vendor":"strongswan"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"libcharon in strongSwan 6.0.0 through 6.0.7 has a use-after-free in IKEv2 rekeying collision handling.","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":"Use after free in strongSwan","id":"CVE-2026-78133","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Auth bypass in strongSwan","id":"CVE-2026-78134"},"packages":[],"prev":{"headline":"Denial of service in strongSwan","id":"CVE-2026-78132"},"products":["strongSwan"],"published":"2026-09-11","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-41913","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2023-26463","kev_date_added":null,"published":"2023-04-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2015-3991","kev_date_added":null,"published":"2017-09-07"},{"cvss_score":7.7,"headline":"Auth bypass in strongSwan","id":"CVE-2022-4967","kev_date_added":null,"published":"2024-05-13"},{"cvss_score":7.5,"headline":"Null dereference in strongSwan","id":"CVE-2026-78130","kev_date_added":null,"published":"2026-09-11"},{"cvss_score":7.5,"headline":"Denial of service in strongSwan","id":"CVE-2026-78132","kev_date_added":null,"published":"2026-09-11"}],"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":"total"},"state":"PUBLISHED","updated":"2026-09-11","vendors":["strongSwan"]},"summary":"A use-after-free in strongSwan's IKEv2 rekeying allows attackers to potentially execute code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2026-78133/"}
