Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-39521 in the wild and no public exploit code.\n\nAffected product: Nelio Content. 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-2026-39521/ (Markdown: https://insights.sbomify.com/CVE-2026-39521/index.md)","id":"CVE-2026-39521","markdown":"https://insights.sbomify.com/CVE-2026-39521/index.md","name":"CVE-2026-39521","record":{"aliases":["GHSA-7vhv-799g-fcfv"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"An attacker can exploit a Server-Side Request Forgery vulnerability in the Nelio Content plugin to make arbitrary requests from the server.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Server-Side Request Forgery (SSRF) vulnerability in Nelio Software Nelio Content nelio-content allows Server Side Request Forgery.This issue affects Nelio Content: from n/a through \u003c= 4.3.1.","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 Nelio Content plugin \u003c= 4.3.1 - Server Side Request Forgery (SSRF) vulnerability","id":"CVE-2026-39521","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress Solene theme \u003c= 3.4 - Local File Inclusion vulnerability","id":"CVE-2026-39522"},"packages":[],"prev":{"headline":"WordPress weDocs plugin \u003c= 2.1.18 - Broken Access Control vulnerability","id":"CVE-2026-39520"},"products":["Nelio Content"],"published":"2026-04-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-29","vendors":["Nelio Software"]},"summary":"An attacker can exploit a Server-Side Request Forgery vulnerability in the Nelio Content plugin to make arbitrary requests from the server.","url":"https://insights.sbomify.com/CVE-2026-39521/"}
