An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2016-8869 exists.\n\nAffected product: Joomla Joomla\\!. 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-2016-8869/ (Markdown: https://insights.sbomify.com/CVE-2016-8869/index.md)","id":"CVE-2016-8869","markdown":"https://insights.sbomify.com/CVE-2016-8869/index.md","name":"CVE-2016-8869","record":{"aliases":["GHSA-v4hj-3rpq-j2ch"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla CMS","requires_auth":"none","summary":"Remote attackers can gain elevated privileges by exploiting improper input validation during user registration in Joomla.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"joomla\\!","vendor":"joomla"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The register method in the UsersModelRegistration class in controllers/user.php in the Users component in Joomla! before 3.6.4 allows remote attackers to gain privileges by leveraging incorrect use of unfiltered data when registering on a site.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2016-10-25","github_poc":3,"max_poc_stars":7,"metasploit":1,"nuclei":0,"refs":[{"date":"2016-11-10T13:47:01Z","kind":"github_poc","ref":"https://github.com/rustyJ4ck/JoomlaCVE20168869","stars":7,"title":"Exploit for Joomla 3.4.4 - 3.6.4 (CVE-2016-8869 and CVE-2016-8870)"},{"date":"2016-10-25","kind":"metasploit","ref":"auxiliary/admin/http/joomla_registration_privesc","stars":null,"title":"Joomla Account Creation and Privilege Escalation"},{"date":"2016-10-27","kind":"exploitdb","ref":"40637","stars":null,"title":"Joomla! 3.4.4 \u003c 3.6.4 - Account Creation / Privilege Escalation"},{"date":"2016-11-02T14:35:58Z","kind":"github_poc","ref":"https://github.com/zugetor/Joomla-3.4.4-3.6.4_CVE-2016-8869_and_CVE-2016-8870","stars":0,"title":"Source code: https://github.com/XiphosResearch/exploits/tree/master/Joomraa"},{"date":"2019-01-11T21:00:52Z","kind":"github_poc","ref":"https://github.com/cved-sources/cve-2016-8869","stars":0,"title":"cve-2016-8869"}],"tier":"weaponised"},"has_fix":false,"headline":"Privilege escalation in n/a","id":"CVE-2016-8869","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"joomla:joomla\\!","products":["joomla:joomla\\!"],"type":"privilege_escalation","year":"2016"},"n_packages":0,"n_references":8,"next":{"headline":"Missing authorization in n/a","id":"CVE-2016-8870"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2016-8867"},"products":["n/a"],"published":"2016-11-04","related":[{"cvss_score":9.8,"headline":"PHPMailer Command Injection","id":"CVE-2016-10033","kev_date_added":"2025-07-07","published":"2016-12-30"},{"cvss_score":5.3,"headline":"Joomla!
