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-2026-13439 in the wild and no public exploit code.\n\nAffected product: hassantafreshi Easy Form Builder by WhiteStudio – Drag \u0026 Drop Form 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-2026-13439/ (Markdown: https://insights.sbomify.com/CVE-2026-13439/index.md)","id":"CVE-2026-13439","markdown":"https://insights.sbomify.com/CVE-2026-13439/index.md","name":"CVE-2026-13439","record":{"aliases":["GHSA-3h5m-xwq3-mjmq"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can escalate privileges to administrator by exploiting weak password recovery tokens in the Easy Form Builder WordPress plugin.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-269","name":"Improper Privilege Management"}],"description":"The Easy Form Builder by WhiteStudio plugin for WordPress is vulnerable to Unauthenticated Privilege Escalation to Administrator in versions up to, and including, 4.0.11 This is due to the password recovery flow using the publicly-visible session identifier ('sid') as the password reset token stored in wp_emsfb_temp_links, combined with a publicly-accessible nonce refresh endpoint (Emsfb/v1/nonce/refresh) that issues valid WordPress REST nonces to unauthenticated visitors. This makes it possible for unauthenticated attackers to reset the password of any WordPress user — including administrators — by scraping the public sid from a published login form page, submitting a recovery request for any known user email via Emsfb/v1/forms/message/add, and then calling Emsfb/v1/forms/recovery/efb_set_password with the known sid to set an arbitrary new password and gain full administrator access.","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":"Privilege escalation in Easy Form Builder by WhiteStudio – Drag \u0026 Drop Form Builder","id":"CVE-2026-13439","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"Cross-site scripting in StoreGrowth – Upsell, BOGO, Quick View, Direct Checkout \u0026 Side Cart for WooCommerce","id":"CVE-2026-13440"},"packages":[],"prev":{"headline":"Information disclosure in PowerShell Universal","id":"CVE-2026-13437"},"products":["Easy Form Builder by WhiteStudio – Drag \u0026 Drop Form Builder"],"published":"2026-07-21","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":"2026-07-21","vendors":["hassantafreshi"]},"summary":"Unauthenticated attackers can escalate privileges to administrator by exploiting weak password recovery tokens in the Easy Form Builder WordPress plugin.","url":"https://insights.sbomify.com/CVE-2026-13439/"}
