Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-53514 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- better-auth (npm): affected all versions; fixed in 1.6.11\n- better-auth (npm): affected all versions; fixed in 1.6.11\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-2026-53514/ (Markdown: https://insights.sbomify.com/CVE-2026-53514/index.md)","id":"CVE-2026-53514","markdown":"https://insights.sbomify.com/CVE-2026-53514/index.md","name":"CVE-2026-53514","record":{"aliases":["GHSA-fmh4-wcc4-5jm3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"TypeScript auth library","requires_auth":"low_privilege","summary":"Attackers can accept organization invitations without verified email ownership if specific configuration options are disabled, leading to unauthorized access.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"better_auth","vendor":"better-auth"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-441","name":"Unintended Proxy or Intermediary"},{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"},{"id":"CWE-287","name":"Improper Authentication"}],"description":"Better Auth is an authentication and authorization library for TypeScript. Prior to 1.6.11, and in 1.6.14 and later when invitation IDs can be obtained outside the invited mailbox and requireEmailVerificationOnInvitation: true is not enabled, the organization plugin's acceptInvitation, rejectInvitation, getInvitation, and listUserInvitations recipient endpoints use session.user.email and an invitation ID without sufficient verified-email ownership proof, allowing a user with an unverified session for the invited email address to accept an organization invitation after obtaining the invitation ID. This issue is fixed for the original default behavior in version 1.6.11, while 1.6.14 restored compatibility for built-in opaque invitation IDs and leaves affected configurations requiring secure options.","ecosystems":["npm"],"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":"Better Auth: Unauthorized invitation acceptance via unverified email match in organization plugin","id":"CVE-2026-53514","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":2,"n_references":4,"next":{"headline":"Better Auth: Privilege escalation via SSO provider registration: missing admin role check in @better-auth/sso","id":"CVE-2026-53515"},"packages":[{"ecosystem":"npm","fixed":["1.6.11"],"introduced":["0"],"last_affected":[],"package":"better-auth","purl":null,"source":"GHSA-fmh4-wcc4-5jm3"},{"ecosystem":"npm","fixed":["1.6.11"],"introduced":["0"],"last_affected":[],"package":"better-auth","purl":"pkg:npm/better-auth","source":"GHSA-fmh4-wcc4-5jm3"}],"prev":{"headline":"Better Auth: Server-side request forgery via unvalidated OIDC endpoints on @better-auth/sso provider registration","id":"CVE-2026-53513"},"products":["better-auth"],"published":"2026-07-15","related":[{"cvss_score":9.1,"headline":"Better Auth: OAuth refresh-token replay via missing client authentication on oidc-provider and mcp plugins","id":"CVE-2026-53512","kev_date_added":null,"published":"2026-07-15"},{"cvss_score":8.3,"headline":"Better Auth: Account takeover via OAuth auto-link to unverified pre-registered email","id":"CVE-2026-53516","kev_date_added":null,"published":"2026-07-15"},{"cvss_score":7.9,"headline":"Better Auth has an Open Redirect Vulnerability in Verify Email Endpoint","id":"CVE-2024-56734","kev_date_added":null,"published":"2024-12-30"},{"cvss_score":7.6,"headline":"Better Auth: Device authorization approve and deny accept any authenticated session while the user code is pending","id":"CVE-2026-45337","kev_date_added":null,"published":"2026-07-15"},{"cvss_score":6.9,"headline":"Beter Auth has an Open Redirect via Scheme-Less Callback Parameter","id":"CVE-2025-27143","kev_date_added":null,"published":"2025-02-24"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2026-07-18","vendors":["better-auth"]},"summary":"Attackers can accept organization invitations without verified email ownership if specific configuration options are disabled, leading to unauthorized access.","url":"https://insights.sbomify.com/CVE-2026-53514/"}
