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-2025-64500 exists.\n\nAffected packages and fixed versions:\n- symfony/http-foundation (Packagist): affected all versions; fixed in 5.4.50\n- symfony/http-foundation (Packagist): affected all versions; fixed in 5.4.50\n- symfony/http-foundation (Packagist): affected from 6.0.0; fixed in 6.4.29\n- symfony/http-foundation (Packagist): affected from 6.0.0; fixed in 6.4.29\n- symfony/http-foundation (Packagist): affected from 7.0.0; fixed in 7.3.7\n- symfony/http-foundation (Packagist): affected from 7.0.0; fixed in 7.3.7\n- symfony/symfony (Packagist): affected from 2.0.0; fixed in 5.4.50\n- symfony/symfony (Packagist): affected from 2.0.0; fixed in 5.4.50\n- symfony/symfony (Packagist): affected from 6.0.0; fixed in 6.4.29\n- symfony/symfony (Packagist): affected from 6.0.0; fixed in 6.4.29\n- symfony/symfony (Packagist): affected from 7.0.0; fixed in 7.3.7\n- symfony/symfony (Packagist): affected from 7.0.0; fixed in 7.3.7\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-2025-64500/ (Markdown: https://insights.sbomify.com/CVE-2025-64500/index.md)","id":"CVE-2025-64500","markdown":"https://insights.sbomify.com/CVE-2025-64500/index.md","name":"CVE-2025-64500","record":{"aliases":["CLSA-2025-1766451449","CLSA-2026-1768265576","DEBIAN-CVE-2025-64500","GHSA-3rg7-wf37-54rm","UBUNTU-CVE-2025-64500"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP web framework","requires_auth":"none","summary":"Attackers can bypass access control rules in Symfony applications by exploiting improper PATH_INFO parsing that violates path prefix assumptions.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"httpfoundation","vendor":"sensiolabs"},{"product":"symfony","vendor":"sensiolabs"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-647","name":"Use of Non-Canonical URL Paths for Authorization Decisions"}],"description":"Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Symfony's HttpFoundation component defines an object-oriented layer for the HTTP specification. Starting in version 2.0.0 and prior to version 5.4.50, 6.4.29, and 7.3.7, the `Request` class improperly interprets some `PATH_INFO` in a way that leads to representing some URLs with a path that doesn't start with a `/`. This can allow bypassing some access control rules that are built with this `/`-prefix assumption. Starting in versions 5.4.50, 6.4.29, and 7.3.7, the `Request` class now ensures that URL paths always start with a `/`.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2025/CVE-2025-64500.yaml","stars":null,"title":"Symfony HttpFoundation - Access Control Bypass via PATH_INFO"}],"tier":"weaponised"},"has_fix":true,"headline":"Symfony's incorrect parsing of PATH_INFO can lead to limited authorization bypass","id":"CVE-2025-64500","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"sensiolabs:symfony","products":["sensiolabs:symfony"],"type":"auth_bypass","year":"2025"},"n_packages":12,"n_references":5,"next":{"headline":"ProsemirrorToHtml: Cross-Site Scripting vulnerability through unescaped HTML attribute values","id":"CVE-2025-64501"},"packages":[{"ecosystem":"Packagist","fixed":["5.4.50"],"introduced":["0"],"last_affected":[],"package":"symfony/http-foundation","purl":null,"source":"GHSA-3rg7-wf37-54rm"},{"ecosystem":"Packagist","fixed":["5.4.50"],"introduced":["0"],"last_affected":[],"package":"symfony/http-foundation","purl":"pkg:composer/symfony/http-foundation","source":"GHSA-3rg7-wf37-54rm"},{"ecosystem":"Packagist","fixed":["6.4.29"],"introduced":["6.0.0"],"last_affected":[],"package":"symfony/http-foundation","purl":null,"source":"GHSA-3rg7-wf37-54rm"},{"ecosystem":"Packagist","fixed":["6.4.29"],"introduced":["6.0.0"],"last_affected":[],"package":"symfony/http-foundation","purl":"pkg:composer/symfony/http-foundation","source":"GHSA-3rg7-wf37-54rm"},{"ecosystem":"Packagist","fixed":["7.3.7"],"introduced":["7.0.0"],"last_affected":[],"package":"symfony/http-foundation","purl":null,"source":"GHSA-3rg7-wf37-54rm"},{"ecosystem":"Packagist","fixed":["7.3.7"],"introduced":["7.0.0"],"last_affected":[],"package":"symfony/http-foundation","purl":"pkg:composer/symfony/http-foundation","source":"GHSA-3rg7-wf37-54rm"},{"ecosystem":"Packagist","fixed":["5.4.50"],"introduced":["2.0.0"],"last_affected":[],"package":"symfony/symfony","purl":null,"source":"GHSA-3rg7-wf37-54rm"},{"ecosystem":"Packagist","fixed":["5.4.50"],"introduced":["2.0.0"],"last_affected":[],"package":"symfony/symfony","purl":"pkg:composer/symfony/symfony","source":"GHSA-3rg7-wf37-54rm"},{"ecosystem":"Packagist","fixed":["6.4.29"],"introduced":["6.0.0"],"last_affected":[],"package":"symfony/symfony","purl":null,"source":"GHSA-3rg7-wf37-54rm"},{"ecosystem":"Packagist","fixed":["6.4.29"],"introduced":["6.0.0"],"last_affected":[],"package":"symfony/symfony","purl":"pkg:composer/symfony/symfony","source":"GHSA-3rg7-wf37-54rm"},{"ecosystem":"Packagist","fixed":["7.3.7"],"introduced":["7.0.0"],"last_affected":[],"package":"symfony/symfony","purl":null,"source":"GHSA-3rg7-wf37-54rm"},{"ecosystem":"Packagist","fixed":["7.3.7"],"introduced":["7.0.0"],"last_affected":[],"package":"symfony/symfony","purl":"pkg:composer/symfony/symfony","source":"GHSA-3rg7-wf37-54rm"}],"prev":{"headline":"Tuleap is missing CSRF protections for its planning management API","id":"CVE-2025-64499"},"products":["symfony"],"published":"2025-11-12","related":[],"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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-13","vendors":["symfony"]},"summary":"Attackers can bypass access control rules in Symfony applications by exploiting improper PATH_INFO parsing that violates path prefix assumptions.","url":"https://insights.sbomify.com/CVE-2025-64500/"}
