When authenticating users Symfony by default regenerates the session ID upon login, but preserves the rest of session attributes. Because this does not clear CSRF tokens upon login, this might enables same-site attackers to bypass the CSRF protection mechanism by performing an attack similar to a session-fixation. This issue has been fixed in the 4.4 branch.","severity":{"version":"3.1","score":6.3,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.0079,"percentile":0.566,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-384","CWE-613"],"published":"2023-02-01T18:48:06Z","modified":"2026-11-03T08:02:45Z","fixes":[{"ecosystem":"Packagist","package":"symfony/security-bundle","fixed_in":["4.4.50","5.4.20","6.0.20","6.1.12","6.2.6"],"sources":["ghsa","osv"]},{"ecosystem":"Packagist","package":"symfony/symfony","fixed_in":["4.4.50","5.4.20","6.0.20","6.1.12","6.2.6"],"sources":["ghsa","osv"]},{"ecosystem":"Bitnami","package":"symfony","fixed_in":["4.4.50","5.4.20","6.0.20","6.1.12","6.2.6"],"sources":["osv"]},{"ecosystem":"Debian:12","package":"symfony","fixed_in":["5.4.20+dfsg-1"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"symfony","fixed_in":["5.4.20+dfsg-1"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"symfony","fixed_in":["5.4.20+dfsg-1"],"sources":["osv"]},{"ecosystem":"Ubuntu:Pro:20.04:LTS","package":"symfony","fixed_in":["4.3.8+dfsg-1ubuntu1+esm2"],"sources":["osv"]},{"ecosystem":"Ubuntu:Pro:22.04:LTS","package":"symfony","fixed_in":["5.4.4+dfsg-1ubuntu8+esm1"],"sources":["osv"]}],"affected":[{"source":"ghsa","ecosystem":"Packagist","package":"symfony/security-bundle","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0.0"},{"fixed":"4.4.50"}]}]},{"source":"ghsa","ecosystem":"Packagist","package":"symfony/security-bundle","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.0.0"},{"fixed":"5.4.20"}]}]},{"source":"ghsa","ecosystem":"Packagist","package":"symfony/security-bundle","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"6.0.20"}]}]},{"source":"ghsa","ecosystem":"Packagist","package":"symfony/security-bundle","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.1.12"}]}]},{"source":"ghsa","ecosystem":"Packagist","package":"symfony/security-bundle","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.2.6"}]}]},{"source":"ghsa","ecosystem":"Packagist","package":"symfony/symfony","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0.0"},{"fixed":"4.4.50"}]}]},{"source":"ghsa","ecosystem":"Packagist","package":"symfony/symfony","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.0.0"},{"fixed":"5.4.20"}]}]},{"source":"ghsa","ecosystem":"Packagist","package":"symfony/symfony","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"6.0.20"}]}]},{"source":"ghsa","ecosystem":"Packagist","package":"symfony/symfony","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.1.12"}]}]},{"source":"ghsa","ecosystem":"Packagist","package":"symfony/symfony","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.2.6"}]}]},{"source":"osv","ecosystem":"Bitnami","package":"symfony","ranges":[{"type":"SEMVER","events":[{"introduced":"2.0.0"},{"fixed":"4.4.50"},{"introduced":"5.0.0"},{"fixed":"5.4.20"},{"introduced":"6.0.0"},{"fixed":"6.0.20"},{"introduced":"6.1.0"},{"fixed":"6.1.12"},{"introduced":"6.2.0"},{"fixed":"6.2.6"}]}]},{"source":"osv","ecosystem":"Debian:12","package":"symfony","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.4.20+dfsg-1"}]}]},{"source":"osv","ecosystem":"Debian:13","package":"symfony","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.4.20+dfsg-1"}]}]},{"source":"osv","ecosystem":"Debian:14","package":"symfony","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.4.20+dfsg-1"}]}]},{"source":"osv","ecosystem":"Debian:10","package":"symfony","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.22+dfsg-2+deb10u2"}]}],"versions":["3.4.22+dfsg-2","3.4.22+dfsg-2+deb10u1"],"bundled":3},{"source":"osv","ecosystem":"Packagist","package":"symfony/security-bundle","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0.0"},{"fixed":"4.4.50"}]}],"versions":["2.0.7","v2.0.10","v2.0.12","v2.0.13","v2.0.14","v2.0.15","v2.0.16","v2.0.17","v2.0.18","v2.0.19","v2.0.20","v2.0.21","v2.0.22","v2.0.23","v2.0.24","v2.0.25","v2.0.9","v2.1.0","v2.1.1","v2.1.10","v2.1.11","v2.1.12","v2.1.13","v2.1.2","v2.1.3","v2.1.4","v2.1.5","v2.1.6","v2.1.7","v2.1.8","v2.1.9","v2.2.0","v2.2.1","v2.2.10","v2.2.11","v2.2.2","v2.2.3","v2.2.4","v2.2.5","v2.2.6","v2.2.7","v2.2.8","v2.2.9","v2.3.0","v2.3.1","v2.3.10","v2.3.11","v2.3.12","v2.3.13","v2.3.14","v2.3.15","v2.3.16","v2.3.17","v2.3.18","v2.3.19","v2.3.2","v2.3.20","v2.3.21","v2.3.22","v2.3.23","v2.3.24","v2.3.25","v2.3.26","v2.3.27","v2.3.28","v2.3.29","v2.3.3","v2.3.30","v2.3.31","v2.3.32","v2.3.33","v2.3.34","v2.3.35","v2.3.36","v2.3.37","v2.3.38","v2.3.39","v2.3.4","v2.3.40","v2.3.41","v2.3.42","v2.3.5","v2.3.6","v2.3.7","v2.3.8","v2.3.9","v2.4.0","v2.4.0-BETA1","v2.4.0-BETA2","v2.4.0-RC1","v2.4.1","v2.4.10","v2.4.
