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-2021-36567 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- topthink/framework (Packagist): affected all versions up to 6.0.8; no fix listed\n- topthink/framework (Packagist): affected all versions up to 6.0.8; no fix listed\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-2021-36567/ (Markdown: https://insights.sbomify.com/CVE-2021-36567/index.md)","id":"CVE-2021-36567","markdown":"https://insights.sbomify.com/CVE-2021-36567/index.md","name":"CVE-2021-36567","record":{"aliases":["GHSA-qrvj-274h-hfcg"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP framework","requires_auth":"none","summary":"A deserialization vulnerability in ThinkPHP allows attackers to execute arbitrary code via the Flysystem cache component.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"thinkphp","vendor":"thinkphp"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"ThinkPHP v6.0.8 was discovered to contain a deserialization vulnerability via the component League\\Flysystem\\Cached\\Storage\\AbstractCache.","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":false,"headline":"Deserialization of Untrusted Data in topthink/framework","id":"CVE-2021-36567","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"deserialization","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"Moodle Cross-site Scripting vulnerability","id":"CVE-2021-36568"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["6.0.8"],"package":"topthink/framework","purl":null,"source":"GHSA-qrvj-274h-hfcg"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["6.0.8"],"package":"topthink/framework","purl":"pkg:composer/topthink/framework","source":"GHSA-qrvj-274h-hfcg"}],"prev":{"headline":"Deserialization of Untrusted Data in topthink/framework","id":"CVE-2021-36564"},"products":["n/a"],"published":"2021-12-06","related":[{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2025-63888","kev_date_added":null,"published":"2025-11-20"},{"cvss_score":9.8,"headline":"ThinkPHP Path Traversal Vulnerability","id":"CVE-2025-50706","kev_date_added":null,"published":"2025-08-05"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2025-50707","kev_date_added":null,"published":"2025-08-05"},{"cvss_score":9.8,"headline":"ThinkPHP deserialization vulnerability","id":"CVE-2024-48112","kev_date_added":null,"published":"2024-10-30"},{"cvss_score":9.8,"headline":"ThinkPHP deserialization vulnerability","id":"CVE-2024-44902","kev_date_added":null,"published":"2024-09-09"},{"cvss_score":9.8,"headline":"Deserialization of Untrusted Data in thinkphp","id":"CVE-2022-45982","kev_date_added":null,"published":"2023-02-08"},{"cvss_score":9.8,"headline":"ThinkPHP Framework vulnerable to remote code execution","id":"CVE-2022-47945","kev_date_added":null,"published":"2022-12-23"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"A deserialization vulnerability in ThinkPHP allows attackers to execute arbitrary code via the Flysystem cache component.","url":"https://insights.sbomify.com/CVE-2021-36567/"}
