NewCVE-2026-41839 (opens in a new tab)How to fix?
Upgrade org.springframework:spring-web to version 6.0.0, 6.2.19, 7.0.8 or higher.
Overview
org.springframework:spring-web is a package that provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform.
Affected versions of this package are vulnerable to Session Fixation via session fixation handling. An attacker controlling a compromised subdomain can obtain a known session identifier and subsequently cause it to be associated with an authenticated user session, allowing unauthorized use of the victim's authenticated session.
Note: This is only exploitable if an attacker can control or execute script within a subdomain of the target application (for example through a cross-site scripting vulnerability).
