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-2023-40555 in the wild and no public exploit code.\n\nAffected product: UX-themes Flatsome | Multi-Purpose Responsive WooCommerce Theme. 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-2023-40555/ (Markdown: https://insights.sbomify.com/CVE-2023-40555/index.md)","id":"CVE-2023-40555","markdown":"https://insights.sbomify.com/CVE-2023-40555/index.md","name":"CVE-2023-40555","record":{"aliases":["GHSA-9fmf-6xvc-qw23"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress theme","requires_auth":"none","summary":"An attacker can exploit PHP object injection in the Flatsome WordPress theme to potentially execute arbitrary code on the server.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"flatsome","vendor":"uxthemes"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Deserialization of Untrusted Data vulnerability in UX-themes Flatsome | Multi-Purpose Responsive WooCommerce Theme.This issue affects Flatsome | Multi-Purpose Responsive WooCommerce Theme: from n/a through 3.17.5.","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":"WordPress Flatsome Theme \u003c= 3.17.5 is vulnerable to PHP Object Injection","id":"CVE-2023-40555","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress Schedule Posts Calendar Plugin \u003c= 5.2 is vulnerable to Cross Site Request Forgery (CSRF)","id":"CVE-2023-40556"},"packages":[],"prev":{"headline":"WordPress Blog2Social Plugin \u003c= 7.2.0 is vulnerable to Cross Site Scripting (XSS)","id":"CVE-2023-40554"},"products":["Flatsome | Multi-Purpose Responsive WooCommerce Theme"],"published":"2023-12-20","related":[{"cvss_score":7.1,"headline":"WordPress Flatsome Theme \u003c= 3.16.8 is vulnerable to Cross Site Scripting (XSS)","id":"CVE-2023-28994","kev_date_added":null,"published":"2023-08-23"},{"cvss_score":6.4,"headline":"Cross-site scripting in Flatsome","id":"CVE-2024-5346","kev_date_added":null,"published":"2024-06-22"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-04-28","vendors":["UX-themes"]},"summary":"An attacker can exploit PHP object injection in the Flatsome WordPress theme to potentially execute arbitrary code on the server.","url":"https://insights.sbomify.com/CVE-2023-40555/"}
