It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-55706 exists.\n\nAffected product: Openbsd Openbsd. 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-2026-55706/ (Markdown: https://insights.sbomify.com/CVE-2026-55706/index.md)","id":"CVE-2026-55706","markdown":"https://insights.sbomify.com/CVE-2026-55706/index.md","name":"CVE-2026-55706","record":{"aliases":["GHSA-rrgf-j5xj-h9hc"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenBSD PPP","requires_auth":"none","summary":"An attacker can bypass PPP authentication in OpenBSD by exploiting improper length validation in the PAP input handler.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openbsd","vendor":"openbsd"}],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-1284","name":"Improper Validation of Specified Quantity in Input"}],"description":"sppp_pap_input in sys/net/if_spppsubr.c in OpenBSD before 076e2b1 allows authentication bypass via certain zero values for lengths.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Auth bypass in OpenBSD","id":"CVE-2026-55706","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openbsd:openbsd","products":["openbsd:openbsd"],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Missing authorization in Neutron","id":"CVE-2026-55707"},"packages":[],"prev":{"headline":"Discourse: Shared-draft titles and excerpts leak through group post serialization","id":"CVE-2026-55704"},"products":["OpenBSD"],"published":"2026-06-17","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-1365","kev_date_added":null,"published":"2007-03-10"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2004-0220","kev_date_added":null,"published":"2004-03-25"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0083","kev_date_added":null,"published":"2004-02-14"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0084","kev_date_added":null,"published":"2004-02-14"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2001-0284","kev_date_added":null,"published":"2001-05-07"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2000-1010","kev_date_added":null,"published":"2001-01-22"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2020-16088","kev_date_added":null,"published":"2020-07-28"}],"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-17","vendors":["OpenBSD"]},"summary":"An attacker can bypass PPP authentication in OpenBSD by exploiting improper length validation in the PAP input handler.","url":"https://insights.sbomify.com/CVE-2026-55706/"}
