Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-4237 exists.\n\nAffected product: Unknown Welcart e-Commerce. 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-2022-4237/ (Markdown: https://insights.sbomify.com/CVE-2022-4237/index.md)","id":"CVE-2022-4237","markdown":"https://insights.sbomify.com/CVE-2022-4237/index.md","name":"CVE-2022-4237","record":{"aliases":["GHSA-x65c-cg4w-m3j6"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated subscribers can trigger PHAR deserialization via file uploads, potentially leading to remote code execution on the WordPress site.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"welcart_e-commerce","vendor":"welcart"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"The Welcart e-Commerce WordPress plugin before 2.8.6 does not validate user input before using it in file_exist() functions via various AJAX actions available to any authenticated users, which could allow users with a role as low as subscriber to perform PHAR deserialisation when they can upload a file and a suitable gadget chain is present on the blog","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Welcart e-Commerce \u003c 2.8.6 - Subscriber+ PHAR Deserialisation","id":"CVE-2022-4237","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Workreap \u003c 2.6.4 - Subscriber+ Arbitrary Posts Deletion via IDOR","id":"CVE-2022-4239"},"packages":[],"prev":{"headline":"Welcart e-Commerce \u003c 2.8.5 - Subscriber+ Arbitrary File Access","id":"CVE-2022-4236"},"products":["Welcart e-Commerce"],"published":"2023-01-02","related":[{"cvss_score":9.8,"headline":"Welcart e-Commerce \u003c 2.9.5 - Unauthenticated PHP Object Injection","id":"CVE-2023-5952","kev_date_added":null,"published":"2023-12-04"},{"cvss_score":8.8,"headline":"SQL injection in Welcart e-Commerce","id":"CVE-2024-42404","kev_date_added":null,"published":"2024-09-18"},{"cvss_score":8.8,"headline":"Welcart e-Commerce \u003c 2.9.5 - Subscriber+ Arbitrary File Upload","id":"CVE-2023-5953","kev_date_added":null,"published":"2023-12-04"},{"cvss_score":8.8,"headline":"SQL injection in Welcart e-Commerce","id":"CVE-2023-43610","kev_date_added":null,"published":"2023-09-26"},{"cvss_score":7.6,"headline":"WordPress Welcart e-Commerce Plugin \u003c= 2.9.3 is vulnerable to SQL Injection","id":"CVE-2023-50847","kev_date_added":null,"published":"2023-12-28"},{"cvss_score":7.5,"headline":"Welcart e-Commerce \u003c 2.2.8 - Missing Capabilities Check to Information Disclosure","id":"CVE-2021-4355","kev_date_added":null,"published":"2023-06-07"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-10","vendors":["Unknown"]},"summary":"Authenticated subscribers can trigger PHAR deserialization via file uploads, potentially leading to remote code execution on the WordPress site.","url":"https://insights.sbomify.com/CVE-2022-4237/"}
