Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-16557 in the wild and no public exploit code.\n\nAffected product: Unknown Nimble Page Builder. 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-2026-16557/ (Markdown: https://insights.sbomify.com/CVE-2026-16557/index.md)","id":"CVE-2026-16557","markdown":"https://insights.sbomify.com/CVE-2026-16557/index.md","name":"CVE-2026-16557","record":{"aliases":["GHSA-4c39-75m8-74f3"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated users can access non-public page-builder content due to missing authorization checks in the Nimble Page Builder WordPress plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"The Nimble Page Builder WordPress plugin through 3.3.8 does not perform an authorization check when returning page-builder content through an authenticated AJAX action, allowing any authenticated user (Subscriber+) to disclose the page-builder content of arbitrary non-public (draft, pending, private, scheduled) posts and pages.","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":"Nimble Builder \u003c= 3.3.8 - Subscriber+ Non-Public Content Disclosure via sek_get_nimble_content_for_seo_plugins","id":"CVE-2026-16557","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"YMC Filter \u003c 3.12.8 - Contributor+ Stored XSS via Layout Builder Schema","id":"CVE-2026-16558"},"packages":[],"prev":{"headline":"Integer Overflow Leading to Heap Buffer Overflow in cJSON","id":"CVE-2026-16554"},"products":["Nimble Page Builder"],"published":"2026-09-19","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":"partial"},"state":"PUBLISHED","updated":"2026-09-19","vendors":["Unknown"]},"summary":"Authenticated users can access non-public page-builder content due to missing authorization checks in the Nimble Page Builder WordPress plugin.","url":"https://insights.sbomify.com/CVE-2026-16557/"}
