An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-100684 exists.\n\nAffected product: budibase server. 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-2026-100684/ (Markdown: https://insights.sbomify.com/CVE-2026-100684/index.md)","id":"CVE-2026-100684","markdown":"https://insights.sbomify.com/CVE-2026-100684/index.md","name":"CVE-2026-100684","record":{"aliases":["GHSA-35ch-57g2-3g98","GHSA-g8px-vqwp-7rg7"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Budibase server","requires_auth":"none","summary":"Attackers can hijack pending user invites via OIDC to gain admin privileges and compromise tenant data.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Budibase versions 3.41.0 before 3.45.0 contain an authentication bypass in the OIDC/SSO login path of @budibase/server. In sso.authenticate, when no existing user matches the incoming SSO subject, the server looks up pending user invites by the IdP-asserted email address alone — without validating an invite code and without an email_verified check (the email_verified gate protects only the existing-account lookup). An attacker who can register at an IdP that the tenant trusts for OIDC and assert a victim's invited email address (even with email_verified=false) claims the pending invite and inherits all of its granted privileges, including builder and admin.global, with no admin exclusion. This results in takeover of the invited principal and, for admin invites, full tenant compromise (access to all apps, datasources including production credentials, and automations); the invite is consumed, denying onboarding to the legitimate invitee.","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":"Budibase Server 3.41.0 before 3.45.0 Authentication Bypass via OIDC","id":"CVE-2026-100684","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Budibase before 3.45.0 Information Disclosure via Chat Links","id":"CVE-2026-100685"},"packages":[],"prev":{"headline":"Budibase before 3.45.0 SQL Injection via column-rename DDL","id":"CVE-2026-100683"},"products":["server"],"published":"2026-09-26","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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-08","vendors":["budibase"]},"summary":"Attackers can hijack pending user invites via OIDC to gain admin privileges and compromise tenant data.","url":"https://insights.sbomify.com/CVE-2026-100684/"}
