An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-2991 in the wild and no public exploit code.\n\nAffected product: iqonicdesign KiviCare – Clinic \u0026 Patient Management System (EHR). 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-2026-2991/ (Markdown: https://insights.sbomify.com/CVE-2026-2991/index.md)","id":"CVE-2026-2991","markdown":"https://insights.sbomify.com/CVE-2026-2991/index.md","name":"CVE-2026-2991","record":{"aliases":["GHSA-vgm8-mf6q-65v2"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication to access patient medical records and potentially administrator cookies by exploiting a missing token verification in the social login function.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The KiviCare – Clinic \u0026 Patient Management System (EHR) plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 4.1.2. This is due to the `patientSocialLogin()` function not verifying the social provider access token before authenticating a user. This makes it possible for unauthenticated attackers to log in as any patient registered on the system by providing only their email address and an arbitrary value for the access token, bypassing all credential verification. The attacker gains access to sensitive medical records, appointments, prescriptions, and billing information (PII/PHI breach). Additionally, authentication cookies are set before the role check, meaning the auth cookies for non-patient users (including administrators) are also set in the HTTP response headers, even though a 403 response is returned.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-03-18","github_poc":1,"max_poc_stars":4,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-03-18T19:09:24Z","kind":"github_poc","ref":"https://github.com/joshuavanderpoll/CVE-2026-2991","stars":4,"title":"PoC exploit for CVE-2026-2991 — authentication bypass in KiviCare WordPress plugin (≤4.1.2) allowing unauthenticated patient account takeover and admin session extraction."}],"tier":"poc_unverified"},"has_fix":null,"headline":"Auth bypass in KiviCare – Clinic \u0026 Patient Management System (EHR)","id":"CVE-2026-2991","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"KiviCare \u003c= 4.1.2 - Missing Authorization to Unauthenticated Privilege Escalation via Setup Wizard","id":"CVE-2026-2992"},"packages":[],"prev":{"headline":"Cross-site scripting in PowerPress Podcasting plugin by Blubrry","id":"CVE-2026-2988"},"products":["KiviCare – Clinic \u0026 Patient Management System (EHR)"],"published":"2026-03-18","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-08","vendors":["iqonicdesign"]},"summary":"Unauthenticated attackers can bypass authentication to access patient medical records and potentially administrator cookies by exploiting a missing token verification in the social login function.","url":"https://insights.sbomify.com/CVE-2026-2991/"}
