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-2026-45069 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- symfony/security-http (Packagist): affected from 6.3.0; fixed in 6.4.40\n- symfony/security-http (Packagist): affected from 6.3.0; fixed in 6.4.40\n- symfony/security-http (Packagist): affected from 7.4.0; fixed in 7.4.12\n- symfony/security-http (Packagist): affected from 7.4.0; fixed in 7.4.12\n- symfony/security-http (Packagist): affected from 8.0.0; fixed in 8.0.12\n- symfony/security-http (Packagist): affected from 8.0.0; fixed in 8.0.12\n- symfony/symfony (Packagist): affected from 6.3.0; fixed in 6.4.40\n- symfony/symfony (Packagist): affected from 6.3.0; fixed in 6.4.40\n- symfony/symfony (Packagist): affected from 7.4.0; fixed in 7.4.12\n- symfony/symfony (Packagist): affected from 7.4.0; fixed in 7.4.12\n- symfony/symfony (Packagist): affected from 8.0.0; fixed in 8.0.12\n- symfony/symfony (Packagist): affected from 8.0.0; fixed in 8.0.12\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-2026-45069/ (Markdown: https://insights.sbomify.com/CVE-2026-45069/index.md)","id":"CVE-2026-45069","markdown":"https://insights.sbomify.com/CVE-2026-45069/index.md","name":"CVE-2026-45069","record":{"aliases":["DEBIAN-CVE-2026-45069","GHSA-29fc-p6c4-24cg","UBUNTU-CVE-2026-45069"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Symfony security component","requires_auth":"none","summary":"Attackers can bypass authentication in Symfony applications by using JWTs missing mandatory claims, as the token handler fails to enforce their presence.","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":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"},{"id":"CWE-1287","name":"Improper Validation of Specified Type of Input"}],"description":"Symfony is a PHP framework for web and console applications and a set of reusable PHP components.
