Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-46733 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- symfony/security-http (Packagist): affected from 5.4.21; fixed in 5.4.31\n- symfony/security-http (Packagist): affected from 5.4.21; fixed in 5.4.31\n- symfony/security-http (Packagist): affected from 6.2.7; fixed in 6.3.8\n- symfony/security-http (Packagist): affected from 6.2.7; fixed in 6.3.8\n- symfony (Bitnami): affected from 5.4.21; fixed in 5.4.31, 6.3.8\n- symfony/symfony (Packagist): affected from 5.4.21; fixed in 5.4.31\n- symfony/symfony (Packagist): affected from 5.4.21; fixed in 5.4.31\n- symfony/symfony (Packagist): affected from 6.2.7; fixed in 6.3.8\n- symfony/symfony (Packagist): affected from 6.2.7; fixed in 6.3.8\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-2023-46733/ (Markdown: https://insights.sbomify.com/CVE-2023-46733/index.md)","id":"CVE-2023-46733","markdown":"https://insights.sbomify.com/CVE-2023-46733/index.md","name":"CVE-2023-46733","record":{"aliases":["BIT-symfony-2023-46733","DEBIAN-CVE-2023-46733","GHSA-m2wj-r6g3-fxfx"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP web framework","requires_auth":"low_privilege","summary":"Attackers can hijack user sessions by exploiting a failure to regenerate session IDs during specific login transitions in the Symfony framework.","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":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-384","name":"Session Fixation"}],"description":"Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Starting in versions 5.4.21 and 6.2.7 and prior to versions 5.4.31 and 6.3.8, `SessionStrategyListener` does not migrate the session after every successful login. It does so only in case the logged in user changes by means of checking the user identifier. In some use cases, the user identifier doesn't change between the verification phase and the successful login, while the token itself changes from one type (partially-authenticated) to another (fully-authenticated). When this happens, the session id should be regenerated to prevent possible session fixations, which is not the case at the moment. As of versions 5.4.31 and 6.3.8, Symfony now checks the type of the token in addition to the user identifier before deciding whether the session id should be regenerated.","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":"Symfony possible session fixation vulnerability","id":"CVE-2023-46733","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"sensiolabs:symfony","products":["sensiolabs:symfony"],"type":"auth_bypass","year":"2023"},"n_packages":9,"n_references":3,"next":{"headline":"Symfony potential Cross-site Scripting vulnerabilities in CodeExtension filters","id":"CVE-2023-46734"},"packages":[{"ecosystem":"Bitnami","fixed":["5.4.31","6.3.8"],"introduced":["5.4.21","6.2.7"],"last_affected":[],"package":"symfony","purl":"pkg:bitnami/symfony","source":"BIT-symfony-2023-46733"},{"ecosystem":"Packagist","fixed":["5.4.31"],"introduced":["5.4.21"],"last_affected":[],"package":"symfony/security-http","purl":null,"source":"GHSA-m2wj-r6g3-fxfx"},{"ecosystem":"Packagist","fixed":["5.4.31"],"introduced":["5.4.21"],"last_affected":[],"package":"symfony/security-http","purl":"pkg:composer/symfony/security-http","source":"GHSA-m2wj-r6g3-fxfx"},{"ecosystem":"Packagist","fixed":["6.3.8"],"introduced":["6.2.7"],"last_affected":[],"package":"symfony/security-http","purl":null,"source":"GHSA-m2wj-r6g3-fxfx"},{"ecosystem":"Packagist","fixed":["6.3.8"],"introduced":["6.2.7"],"last_affected":[],"package":"symfony/security-http","purl":"pkg:composer/symfony/security-http","source":"GHSA-m2wj-r6g3-fxfx"},{"ecosystem":"Packagist","fixed":["5.4.31"],"introduced":["5.4.21"],"last_affected":[],"package":"symfony/symfony","purl":null,"source":"GHSA-m2wj-r6g3-fxfx"},{"ecosystem":"Packagist","fixed":["5.4.31"],"introduced":["5.4.21"],"last_affected":[],"package":"symfony/symfony","purl":"pkg:composer/symfony/symfony","source":"GHSA-m2wj-r6g3-fxfx"},{"ecosystem":"Packagist","fixed":["6.3.8"],"introduced":["6.2.7"],"last_affected":[],"package":"symfony/symfony","purl":null,"source":"GHSA-m2wj-r6g3-fxfx"},{"ecosystem":"Packagist","fixed":["6.3.8"],"introduced":["6.2.7"],"last_affected":[],"package":"symfony/symfony","purl":"pkg:composer/symfony/symfony","source":"GHSA-m2wj-r6g3-fxfx"}],"prev":{"headline":"Reflected Cross-site scripting through revision parameter in content menu in XWiki Platform","id":"CVE-2023-46732"},"products":["symfony"],"published":"2023-11-10","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-03","vendors":["symfony"]},"summary":"Attackers can hijack user sessions by exploiting a failure to regenerate session IDs during specific login transitions in the Symfony framework.","url":"https://insights.sbomify.com/CVE-2023-46733/"}
