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-2021-28254 exists.\n\nAffected packages and fixed versions:\n- laravel (Bitnami): affected from 8.5.9; fixed in 8.5.10\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-2021-28254/ (Markdown: https://insights.sbomify.com/CVE-2021-28254/index.md)","id":"CVE-2021-28254","markdown":"https://insights.sbomify.com/CVE-2021-28254/index.md","name":"CVE-2021-28254","record":{"aliases":["BIT-laravel-2021-28254","GHSA-5hq5-9pj6-4c2r"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Laravel PHP framework","requires_auth":"none","summary":"Attackers can execute arbitrary commands via a deserialization flaw in the destruct function of the Laravel framework.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"laravel","vendor":"laravel"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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":"A deserialization vulnerability in the destruct() function of Laravel v8.5.9 allows attackers to execute arbitrary commands.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Deserialization in n/a","id":"CVE-2021-28254","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"deserialization","year":"2021"},"n_packages":1,"n_references":1,"next":{"headline":"Misconfiguration in n/a","id":"CVE-2021-28269"},"packages":[{"ecosystem":"Bitnami","fixed":["8.5.10"],"introduced":["8.5.9"],"last_affected":[],"package":"laravel","purl":"pkg:bitnami/laravel","source":"BIT-laravel-2021-28254"}],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2021-28250"},"products":["n/a"],"published":"2023-04-18","related":[{"cvss_score":8.1,"headline":"Laravel Deserialization of Untrusted Data","id":"CVE-2018-15133","kev_date_added":"2024-01-16","published":"2018-08-09"},{"cvss_score":7.5,"headline":"Guard bypass in Eloquent models affecting Laravel illuminate database component","id":"CVE-2020-24940","kev_date_added":null,"published":"2020-09-04"},{"cvss_score":7.5,"headline":"Improper Input Validation in Laravel","id":"CVE-2020-24941","kev_date_added":null,"published":"2020-09-04"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2017-16894","kev_date_added":null,"published":"2017-11-20"},{"cvss_score":7.2,"headline":"Query Binding Exploitation in Laravel","id":"CVE-2021-21263","kev_date_added":null,"published":"2021-01-19"},{"cvss_score":6.1,"headline":"Laravel does not properly constrain the host portion of a password-reset URL","id":"CVE-2017-9303","kev_date_added":null,"published":"2017-05-29"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-03-05","vendors":["n/a"]},"summary":"Attackers can execute arbitrary commands via a deserialization flaw in the destruct function of the Laravel framework.","url":"https://insights.sbomify.com/CVE-2021-28254/"}
