CVE-2026-41706: CWE-601: URL Redirection to Untrusted Site (Open Redirect) in Spring Spring Security
Spring Security's CookieRequestCache and CookieServerRequestCache store the pre-authentication request URL in a browser cookie so that users can be redirected back to their intended destination after a successful login. In affected versions, the full absolute URL is stored in the cookie and is used without validation as the post-login redirect target. Affected versions: Spring Security 5.7.0 through 5.7.23; 5.8.0 through 5.8.25; 6.3.0 through 6.3.16; 6.4.0 through 6.4.16; 6.5.0 through 6.5.10; 7.0.0 through 7.0.5.
AI Analysis
Technical Summary
CVE-2026-41706 is an open redirect vulnerability in Spring Security's CookieRequestCache and CookieServerRequestCache. These components store the full absolute URL of the user's pre-authentication request in a browser cookie to redirect users back after login. However, the stored URL is used without validation as the post-login redirect target, allowing attackers to craft URLs that redirect users to untrusted external sites. This affects multiple Spring Security versions from 5.7.0 through 7.0.5 in specified ranges.
Potential Impact
An attacker can exploit this vulnerability to redirect authenticated users to malicious external websites after login, potentially facilitating phishing or other social engineering attacks. The vulnerability has a CVSS 3.1 score of 6.1 (medium severity), indicating limited confidentiality and integrity impact but no availability impact. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, users should consider implementing custom validation of redirect URLs or disabling automatic post-login redirects to untrusted URLs. Monitor the official Spring Security advisories for updates and apply patches once released.
