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-2026-51584 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2026-51584/ (Markdown: https://insights.sbomify.com/CVE-2026-51584/index.md)","id":"CVE-2026-51584","markdown":"https://insights.sbomify.com/CVE-2026-51584/index.md","name":"CVE-2026-51584","record":{"aliases":["GHSA-wgqp-f2p3-x7mp"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Memos note-taking app","requires_auth":"none","summary":"Remote attackers can take over accounts in usememos by exploiting SSO identity matching flaws that rely on attacker-controlled identifiers instead of stable subject claims.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"An issue in usememos v0.27.1 allows a remote attacker to achieve account takeover via the ssoCredentials branch of the SignIn handler in server/router/api/v1/auth_service.go, because SSO identity is matched only on an attacker-controllable identifier without binding to the IdP's stable subject claim.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Auth bypass in n/a","id":"CVE-2026-51584","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":"Auth bypass in n/a","id":"CVE-2026-51597"},"packages":[],"prev":{"headline":"Server-side request forgery in n/a","id":"CVE-2026-51583"},"products":["n/a"],"published":"2026-08-11","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-12","vendors":["n/a"]},"summary":"Remote attackers can take over accounts in usememos by exploiting SSO identity matching flaws that rely on attacker-controlled identifiers instead of stable subject claims.","url":"https://insights.sbomify.com/CVE-2026-51584/"}
