Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-3964 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- elgg/elgg (Packagist): affected all versions; fixed in 3.3.22\n- elgg/elgg (Packagist): affected all versions; fixed in 3.3.22\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-2021-3964/ (Markdown: https://insights.sbomify.com/CVE-2021-3964/index.md)","id":"CVE-2021-3964","markdown":"https://insights.sbomify.com/CVE-2021-3964/index.md","name":"CVE-2021-3964","record":{"aliases":["GHSA-gwpx-q2h9-wxgx"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Elgg social networking","requires_auth":"low_privilege","summary":"Attackers can bypass authorization controls in Elgg by manipulating user-controlled keys, potentially accessing unauthorized resources.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"elgg","vendor":"elgg"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"elgg is vulnerable to Authorization Bypass Through User-Controlled Key","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Authorization Bypass Through User-Controlled Key in elgg/elgg","id":"CVE-2021-3964","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Missing authorization in HP DesignJet Printer","id":"CVE-2021-3965"},"packages":[{"ecosystem":"Packagist","fixed":["3.3.22"],"introduced":["0"],"last_affected":[],"package":"elgg/elgg","purl":null,"source":"GHSA-gwpx-q2h9-wxgx"},{"ecosystem":"Packagist","fixed":["3.3.22"],"introduced":["0"],"last_affected":[],"package":"elgg/elgg","purl":"pkg:composer/elgg/elgg","source":"GHSA-gwpx-q2h9-wxgx"}],"prev":{"headline":"Cross-Site Request Forgery (CSRF) in kevinpapst/kimai2","id":"CVE-2021-3963"},"products":["elgg/elgg"],"published":"2021-12-01","related":[{"cvss_score":9.8,"headline":"SQL injection in Elgg","id":"CVE-2011-2936","kev_date_added":null,"published":"2019-11-12"},{"cvss_score":9,"headline":"Cross-site Scripting (XSS) - Stored in elgg/elgg","id":"CVE-2021-4072","kev_date_added":null,"published":"2021-12-24"},{"cvss_score":6.8,"headline":"Missing authorization in n/a","id":"CVE-2012-6562","kev_date_added":null,"published":"2013-05-23"},{"cvss_score":6.1,"headline":"Elgg Reflected XSS Vulnerability","id":"CVE-2011-2935","kev_date_added":null,"published":"2019-11-12"},{"cvss_score":6.1,"headline":"Elgg open redirect","id":"CVE-2019-11016","kev_date_added":null,"published":"2019-04-08"},{"cvss_score":5.3,"headline":"Exposure of Private Personal Information to an Unauthorized Actor in elgg/elgg","id":"CVE-2021-3980","kev_date_added":null,"published":"2021-12-03"},{"cvss_score":5,"headline":"Information disclosure in n/a","id":"CVE-2011-3733","kev_date_added":null,"published":"2011-09-23"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-08-03","vendors":["elgg"]},"summary":"Attackers can bypass authorization controls in Elgg by manipulating user-controlled keys, potentially accessing unauthorized resources.","url":"https://insights.sbomify.com/CVE-2021-3964/"}
