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-2023-4643 exists.\n\nAffected product: Unknown Enable Media Replace. 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-2023-4643/ (Markdown: https://insights.sbomify.com/CVE-2023-4643/index.md)","id":"CVE-2023-4643","markdown":"https://insights.sbomify.com/CVE-2023-4643/index.md","name":"CVE-2023-4643","record":{"aliases":["GHSA-h9gw-q7wq-vrfv"],"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":"Author-level users can trigger PHP object injection via the Remove Background feature, potentially leading to code execution if suitable gadgets exist.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"enable_media_replace","vendor":"shortpixel"}],"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 Enable Media Replace WordPress plugin before 4.1.3 unserializes user input via the Remove Background feature, which could allow Author+ users to perform PHP Object Injection when a suitable gadget 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":"Enable Media Replace \u003c 4.1.3 - Author+ PHP Object Injection","id":"CVE-2023-4643","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Ad Inserter \u003c= 2.7.30 - Unauthenticated Sensitive Information Exposure via ai_ajax","id":"CVE-2023-4645"},"packages":[],"prev":{"headline":"kk Star Ratings \u003c 5.4.6 - Rating Tampering via Race Condition","id":"CVE-2023-4642"},"products":["Enable Media Replace"],"published":"2023-10-16","related":[{"cvss_score":8.8,"headline":"Enable Media Replace \u003c 4.0.2 - Author+ Arbitrary File Upload","id":"CVE-2023-0255","kev_date_added":null,"published":"2023-02-13"},{"cvss_score":4.9,"headline":"Enable Media Replace \u003c 4.0.0 - Admin+ Path Traversal","id":"CVE-2022-2554","kev_date_added":null,"published":"2022-10-10"},{"cvss_score":4.7,"headline":"Enable Media Replace \u003c= 4.1.4 - Reflected Cross-Site Scripting","id":"CVE-2023-6737","kev_date_added":null,"published":"2024-01-11"}],"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":"2025-04-23","vendors":["Unknown"]},"summary":"Author-level users can trigger PHP object injection via the Remove Background feature, potentially leading to code execution if suitable gadgets exist.","url":"https://insights.sbomify.com/CVE-2023-4643/"}
