Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-55167 in the wild and no public exploit code.\n\nAffected product: LDAPAccountManager lam. 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-2026-55167/ (Markdown: https://insights.sbomify.com/CVE-2026-55167/index.md)","id":"CVE-2026-55167","markdown":"https://insights.sbomify.com/CVE-2026-55167/index.md","name":"CVE-2026-55167","record":{"aliases":["DEBIAN-CVE-2026-55167","GHSA-xgjg-fchx-x3g3","UBUNTU-CVE-2026-55167"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"LDAP management webapp","requires_auth":"low_privilege","summary":"Attackers with valid credentials and session access can reuse WebAuthn challenges, bypassing two-factor authentication requirements in LDAP Account Manager.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-294","name":"Authentication Bypass by Capture-replay"}],"description":"LDAP Account Manager (LAM) is a webfrontend for managing entries (e.g. users, groups, DHCP settings) stored in an LDAP directory. Prior to 9.6, installations with WebAuthn two-factor authentication leave the challenge in the same PHP session after the authentication response is processed. A user who has already completed valid password authentication can therefore retain the same signed WebAuthn ceremony state instead of consuming it once. The practical risk is limited by the requirement for a valid password, the same PHP session, and a valid authenticator signature. This issue is fixed in version 9.6.","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":"LDAP Account Manager: WebAuthn authentication challenge is kept in the PHP session","id":"CVE-2026-55167","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Runtipi: Authenticated arbitrary file write via backup restore symlink planting","id":"CVE-2026-55168"},"packages":[],"prev":{"headline":"Lemur: ACME SSRF + creator-equality IDOR lead to AWS IAM/PKI compromise","id":"CVE-2026-55166"},"products":["lam"],"published":"2026-10-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-20","vendors":["LDAPAccountManager"]},"summary":"Attackers with valid credentials and session access can reuse WebAuthn challenges, bypassing two-factor authentication requirements in LDAP Account Manager.","url":"https://insights.sbomify.com/CVE-2026-55167/"}
