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-2021-23592 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- topthink/framework (Packagist): affected all versions; fixed in 6.0.12\n- topthink/framework (Packagist): affected all versions; fixed in 6.0.12\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-2021-23592/ (Markdown: https://insights.sbomify.com/CVE-2021-23592/index.md)","id":"CVE-2021-23592","markdown":"https://insights.sbomify.com/CVE-2021-23592/index.md","name":"CVE-2021-23592","record":{"aliases":["GHSA-3fpv-54ff-wqfj","SNYK-PHP-TOPTHINKFRAMEWORK-2385695"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP web framework","requires_auth":"none","summary":"An attacker can execute arbitrary code by exploiting insecure deserialization in the Driver class of the topthink/framework PHP library.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"thinkphp","vendor":"thinkphp"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:L/E:P","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"The package topthink/framework before 6.0.12 are vulnerable to Deserialization of Untrusted Data due to insecure unserialize method in the Driver class.","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":"Deserialization of Untrusted Data","id":"CVE-2021-23592","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"deserialization","year":"2021"},"n_packages":2,"n_references":3,"next":{"headline":"Sandbox Bypass","id":"CVE-2021-23594"},"packages":[{"ecosystem":"Packagist","fixed":["6.0.12"],"introduced":["0"],"last_affected":[],"package":"topthink/framework","purl":null,"source":"GHSA-3fpv-54ff-wqfj"},{"ecosystem":"Packagist","fixed":["6.0.12"],"introduced":["0"],"last_affected":[],"package":"topthink/framework","purl":"pkg:composer/topthink/framework","source":"GHSA-3fpv-54ff-wqfj"}],"prev":{"headline":"Prototype Pollution","id":"CVE-2021-23574"},"products":["topthink/framework"],"published":"2022-05-06","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":"2024-09-16","vendors":["n/a"]},"summary":"An attacker can execute arbitrary code by exploiting insecure deserialization in the Driver class of the topthink/framework PHP library.","url":"https://insights.sbomify.com/CVE-2021-23592/"}
