An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-11883 exists.\n\nAffected product: Unknown WebAuthn Provider for Two Factor. 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-2026-11883/ (Markdown: https://insights.sbomify.com/CVE-2026-11883/index.md)","id":"CVE-2026-11883","markdown":"https://insights.sbomify.com/CVE-2026-11883/index.md","name":"CVE-2026-11883","record":{"aliases":["GHSA-758r-7wwh-v6r7"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"Attackers with valid passwords can bypass two-factor authentication in the WebAuthn Provider plugin by submitting malformed requests.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"The WebAuthn Provider for Two Factor WordPress plugin before 2.5.6 does not correctly validate the second-factor authentication response, allowing an attacker who already knows a user's password to bypass the two-factor authentication requirement by submitting a malformed request.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"WebAuthn Provider for Two Factor \u003c 2.5.6 - 2FA Bypass","id":"CVE-2026-11883","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Red Hat Directory Server 11","id":"CVE-2026-11884"},"packages":[],"prev":{"headline":"Builderall for WordPress \u003c 3.0.2 - Unauthenticated OAuth Access Token Poisoning via Public REST Routes","id":"CVE-2026-11882"},"products":["WebAuthn Provider for Two Factor"],"published":"2026-07-01","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-01","vendors":["Unknown"]},"summary":"Attackers with valid passwords can bypass two-factor authentication in the WebAuthn Provider plugin by submitting malformed requests.","url":"https://insights.sbomify.com/CVE-2026-11883/"}
