Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-32693 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- symfony/security-http (Packagist): affected from 5.3.0; fixed in 5.3.2\n- symfony/security-http (Packagist): affected from 5.3.0; fixed in 5.3.2\n- symfony (Bitnami): affected from 5.3.0; fixed in 5.3.2\n- symfony/symfony (Packagist): affected from 5.3.0; fixed in 5.3.2\n- symfony/symfony (Packagist): affected from 5.3.0; fixed in 5.3.2\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-2021-32693/ (Markdown: https://insights.sbomify.com/CVE-2021-32693/index.md)","id":"CVE-2021-32693","markdown":"https://insights.sbomify.com/CVE-2021-32693/index.md","name":"CVE-2021-32693","record":{"aliases":["BIT-symfony-2021-32693","GHSA-rfcf-m67m-jcrq"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"PHP web framework","requires_auth":"low_privilege","summary":"Attackers can bypass authentication boundaries in Symfony apps with multiple firewalls, gaining unauthorized access to protected areas.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"symfony","vendor":"sensiolabs"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Symfony is a PHP framework for web and console applications and a set of reusable PHP components. A vulnerability related to firewall authentication is in Symfony starting with version 5.3.0 and prior to 5.3.2. When an application defines multiple firewalls, the token authenticated by one of the firewalls was available for all other firewalls. This could be abused when the application defines different providers for each part of the application, in such a situation, a user authenticated on a part of the application could be considered authenticated on the rest of the application. Starting in version 5.3.2, a patch ensures that the authenticated token is only available for the firewall that generates it.","ecosystems":["Bitnami","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":"Authentication granted with multiple firewalls","id":"CVE-2021-32693","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"sensiolabs:symfony","products":["sensiolabs:symfony"],"type":"auth_bypass","year":"2021"},"n_packages":5,"n_references":4,"next":{"headline":"Malicious Android application can crash the Nextcloud Android Client","id":"CVE-2021-32694"},"packages":[{"ecosystem":"Bitnami","fixed":["5.3.2"],"introduced":["5.3.0"],"last_affected":[],"package":"symfony","purl":"pkg:bitnami/symfony","source":"BIT-symfony-2021-32693"},{"ecosystem":"Packagist","fixed":["5.3.2"],"introduced":["5.3.0"],"last_affected":[],"package":"symfony/security-http","purl":null,"source":"GHSA-rfcf-m67m-jcrq"},{"ecosystem":"Packagist","fixed":["5.3.2"],"introduced":["5.3.0"],"last_affected":[],"package":"symfony/security-http","purl":"pkg:composer/symfony/security-http","source":"GHSA-rfcf-m67m-jcrq"},{"ecosystem":"Packagist","fixed":["5.3.2"],"introduced":["5.3.0"],"last_affected":[],"package":"symfony/symfony","purl":null,"source":"GHSA-rfcf-m67m-jcrq"},{"ecosystem":"Packagist","fixed":["5.3.2"],"introduced":["5.3.0"],"last_affected":[],"package":"symfony/symfony","purl":"pkg:composer/symfony/symfony","source":"GHSA-rfcf-m67m-jcrq"}],"prev":{"headline":"Activity Watch vulnerable to command execution on macOS via printAppTitle.scpt","id":"CVE-2021-32692"},"products":["symfony"],"published":"2021-06-17","related":[{"cvss_score":9.8,"headline":"Improper Input Validation in Symfony","id":"CVE-2019-11325","kev_date_added":null,"published":"2019-11-21"},{"cvss_score":9.8,"headline":"Symfony Incorrect Access Control","id":"CVE-2017-11365","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Invalid HTTP method overrides allow possible XSS or other attacks in Symfony","id":"CVE-2019-10913","kev_date_added":null,"published":"2019-05-16"},{"cvss_score":9.8,"headline":"Symfony Authentication Bypass","id":"CVE-2018-11407","kev_date_added":null,"published":"2018-06-13"},{"cvss_score":9.8,"headline":"Symfony Authentication Bypass","id":"CVE-2016-2403","kev_date_added":null,"published":"2017-02-07"},{"cvss_score":9.1,"headline":"Symfony: Identity Spoofing via Unanchored DN Regex in X509Authenticator","id":"CVE-2026-45063","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":8.8,"headline":"Symfony: OidcTokenHandler Accepts JWTs Missing aud/iss/exp Claims","id":"CVE-2026-45069","kev_date_added":null,"published":"2026-07-14"}],"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":"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":["symfony"]},"summary":"Attackers can bypass authentication boundaries in Symfony apps with multiple firewalls, gaining unauthorized access to protected areas.","url":"https://insights.sbomify.com/CVE-2021-32693/"}
