Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-4157 in the wild and no public exploit code.\n\nAffected product: techjewel Fluent Forms – Customizable Contact Forms, Survey, Quiz, \u0026 Conversational 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-2024-4157/ (Markdown: https://insights.sbomify.com/CVE-2024-4157/index.md)","id":"CVE-2024-4157","markdown":"https://insights.sbomify.com/CVE-2024-4157/index.md","name":"CVE-2024-4157","record":{"aliases":["GHSA-h74g-q68m-46qw"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated attackers can exploit PHP object injection in Fluent Forms to execute code or access data if a POP chain exists.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[{"product":"contact_form","vendor":"fluentforms"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"The Contact Form Plugin by Fluent Forms for Quiz, Survey, and Drag \u0026 Drop WP Form Builder plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 5.1.15 via deserialization of untrusted input in the extractDynamicValues function. This makes it possible for authenticated attackers, with contributor-level access and above, to inject a PHP Object. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code. Successful exploitation requires the attacker to have \"View Form\" and \"Manage Form\" permissions, which must be explicitly set by an administrator. However, this requirement can be bypassed when this vulnerability is chained with CVE-2024-2771.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-09-16","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-09-16T16:56:42Z","kind":"github_poc","ref":"https://github.com/Ch4os1/CVE-2024-4157-SSRF-RCE-Reverse-Shell","stars":0,"title":"Chaining Havoc C2 SSRF with RCE to get reverse shell on Havoc C2 Server."}],"tier":"poc_unverified"},"has_fix":null,"headline":"Deserialization in Fluent Forms – Customizable Contact Forms, Survey, Quiz, \u0026 Conversational Form Builder","id":"CVE-2024-4157","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Blocksy \u003c= 2.0.42 - Authenticated (Contributor+) Stored Cross-Site Scripting","id":"CVE-2024-4158"},"packages":[],"prev":{"headline":"Cross-site scripting in Essential Addons for Elementor – Popular Elementor Templates \u0026 Widgets","id":"CVE-2024-4156"},"products":["Fluent Forms – Customizable Contact Forms, Survey, Quiz, \u0026 Conversational Form Builder"],"published":"2024-05-22","related":[{"cvss_score":9.8,"headline":"Missing authorization in Fluent Forms – Customizable Contact Forms, Survey, Quiz, \u0026 Conversational Form Builder","id":"CVE-2024-2771","kev_date_added":null,"published":"2024-05-18"},{"cvss_score":9.8,"headline":"FluentForm \u003c 4.3.13 - CSV Injection","id":"CVE-2022-3463","kev_date_added":null,"published":"2022-11-07"},{"cvss_score":8.8,"headline":"CSRF in WP Fluent Forms \u003c 3.6.67 allows stored XSS and Privilege Escalation","id":"CVE-2021-34620","kev_date_added":null,"published":"2021-07-07"},{"cvss_score":7.5,"headline":"Missing authorization in Fluent Forms – Customizable Contact Forms, Survey, Quiz, \u0026 Conversational Form Builder","id":"CVE-2024-2782","kev_date_added":null,"published":"2024-05-18"},{"cvss_score":7.2,"headline":"Cross-site scripting in Fluent Forms – Customizable Contact Forms, Survey, Quiz, \u0026 Conversational Form Builder","id":"CVE-2024-10646","kev_date_added":null,"published":"2024-12-14"},{"cvss_score":6.4,"headline":"Cross-site scripting in Fluent Forms – Customizable Contact Forms, Survey, Quiz, \u0026 Conversational Form Builder","id":"CVE-2024-2772","kev_date_added":null,"published":"2024-05-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-08","vendors":["techjewel"]},"summary":"Authenticated attackers can exploit PHP object injection in Fluent Forms to execute code or access data if a POP chain exists.","url":"https://insights.sbomify.com/CVE-2024-4157/"}
