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-2023-51473 in the wild and no public exploit code.\n\nAffected product: Pixelemu TerraClassifieds – Simple Classifieds Plugin. 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-2023-51473/ (Markdown: https://insights.sbomify.com/CVE-2023-51473/index.md)","id":"CVE-2023-51473","markdown":"https://insights.sbomify.com/CVE-2023-51473/index.md","name":"CVE-2023-51473","record":{"aliases":["GHSA-wfv4-v3vj-4vq5"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Attackers can upload malicious files to execute arbitrary code on WordPress sites using the TerraClassifieds plugin.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"terraclassifieds","vendor":"pixelemu"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Unrestricted Upload of File with Dangerous Type vulnerability in Pixelemu TerraClassifieds – Simple Classifieds Plugin.This issue affects TerraClassifieds – Simple Classifieds Plugin: from n/a through 2.0.3.","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 TerraClassifieds Plugin \u003c= 2.0.3 is vulnerable to Arbitrary File Upload","id":"CVE-2023-51473","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress TerraClassifieds plugin \u003c= 2.0.3 - Cross Site Request Forgery (CSRF) to Account Takeover vulnerability","id":"CVE-2023-51474"},"packages":[],"prev":{"headline":"WordPress Checkout Mestres WP plugin \u003c= 7.1.9.7 - Unauthenticated Account Takeover vulnerability","id":"CVE-2023-51472"},"products":["TerraClassifieds – Simple Classifieds Plugin"],"published":"2023-12-29","related":[],"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":["Pixelemu"]},"summary":"Attackers can upload malicious files to execute arbitrary code on WordPress sites using the TerraClassifieds plugin.","url":"https://insights.sbomify.com/CVE-2023-51473/"}
