Summary
A vulnerability in Spring Security's CookieRequestCache and CookieServerRequestCache stores the full absolute pre-authentication URL in a browser cookie. After login, the user is redirected to this URL without validation, enabling an open redirect attack.
Risk Assessment
Risk of redirecting users to a malicious site after login, potentially leading to credential theft or malware infection.
Recommendation
Update Spring Security to a patched version (e.g., 5.7.24, 5.8.26, 6.3.17, 6.4.17, 6.5.11, 7.0.6 or later).

The ActiveDirectoryLdapAuthenticator in Spring Security versions 3.2.0 to 3.2.1 and 3.1.0 to 3.1.5 does not check the password length. If the directory allows anonymous binds, it may incorrectly authenticate a user who supplies an empty password.
- CVE-2026-59270Critical
Spring Security's embedded UnboundID LDAP server (UnboundIdContainer) unconditionally registers an administrative credential and binds its listener to all available network interfaces. Affected versions include Spring Security 7.1.0, 7.0.0-7.0.6, 6.5.0-6.5.11, 6.4.0-6.4.18, 5.8.0-5.8.27, and 5.7.0-5.7.25.
- CVE-2026-59277Low
Spring Security's InetAddressMatchers utility provides matchInternal() and matchExternal() builders for constructing an InetAddressMatcher that classifies a given IP address as internal (private) or external (public). Affects Spring Security 7.1.0.
- CVE-2026-59276Medium
Several components in Spring Security compare security-sensitive values using standard string equality (String.equals()) rather than a constant-time comparison. Because String.equals() returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the number of leading characters that match the expected value.
- CVE-2026-47877High
Spring Security Authorization Server versions 7.1.0 and 7.0.0-7.0.6 are vulnerable because the default consent page renders user-controlled values without HTML entity encoding.
- CVE-2026-47842Medium
Applications using AesBytesEncryptor with the two-argument constructor or when passing a null IV generator and CBC as the encryption mode encrypt data with AES/CBC using a null (all-zero) initialization vector. Affected versions include Spring Security 5.7.0 through 7.1.0.
- CVE-2026-47841High
An application using Spring Security's WebAuthn support may be vulnerable to user verification bypass when using a distributed HTTP session store. Affected versions: Spring Security 7.1.0, 7.0.0-7.0.6, 6.5.0-6.5.11, 6.4.0-6.4.18.
- CVE-2026-41707High
Authentication Bypass by Capture-replay vulnerability in Spring Security allows Spring Security's DPoPProofJwtDecoderFactory to contain a cache-based replay attack vulnerability. The internal cache storing JWT ID claims has a strict size limit, allowing attackers to evict legitimate entries by flooding the server with dummy requests, then replay intercepted valid DPoP proofs.
- CVE-2026-47838Medium
The SubjectDnX509PrincipalExtractor in Spring Security does not correctly handle certain malformed X.509 certificate CN values, potentially reading the wrong username. A crafted certificate could allow an attacker to impersonate another user. Affected versions: 5.7.0-5.7.24, 5.8.0-5.8.26, 6.3.0-6.3.17, 6.4.0-6.4.17, 6.5.0-6.5.10.
- CVE-2026-41694Low
Vulnerability in Spring Security SAML allows attackers to decrypt SAML Responses and LogoutRequest/LogoutResponse elements without a valid signature, enabling the Service Provider to be used as a decryption oracle. Affects versions 5.7.0-5.7.23, 5.8.0-5.8.25, 6.3.0-6.3.16, 6.4.0-6.4.16, 6.5.0-6.5.10, 7.0.0-7.0.5.
Original NVD description (English source)
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.
