An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-19842 in the wild and no public exploit code.\n\nAffected product: Unknown SAML Single Sign On. 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-2026-19842/ (Markdown: https://insights.sbomify.com/CVE-2026-19842/index.md)","id":"CVE-2026-19842","markdown":"https://insights.sbomify.com/CVE-2026-19842/index.md","name":"CVE-2026-19842","record":{"aliases":["GHSA-qj54-25r3-fmh2"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress SAML plugin","requires_auth":"none","summary":"Unauthenticated attackers can overwrite SAML trust anchors to authenticate as any user, including administrators, in the SAML Single Sign On WordPress plugin.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The SAML Single Sign On  WordPress plugin before 5.4.7 does not verify the signature of a SAML response before storing the certificate it carries, and offers an administrator a one-click control that promotes that stored certificate to the site's trusted signing certificate, allowing unauthenticated attackers to have a certificate of their own trusted and then authenticate as any user, including an administrator.","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":"SAML Single Sign On 4.8.85 - 5.4.6 - Unauthenticated Administrator Account Takeover via SAML Trust Anchor Overwrite","id":"CVE-2026-19842","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"389-ds-base: 389-ds-base: command injection via unescaped ldap dn in cockpit 389 console ldap editor","id":"CVE-2026-19843"},"packages":[],"prev":{"headline":"TRENDNET TEW-813DRU vsftpd vsftpd.conf default permission","id":"CVE-2026-19841"},"products":["SAML Single Sign On"],"published":"2026-08-19","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":"total"},"state":"PUBLISHED","updated":"2026-08-19","vendors":["Unknown"]},"summary":"Unauthenticated attackers can overwrite SAML trust anchors to authenticate as any user, including administrators, in the SAML Single Sign On WordPress plugin.","url":"https://insights.sbomify.com/CVE-2026-19842/"}
