MEDIUM 5.9 NVD
CVE-2026-59276
Several components in Spring Security compare security-sensitive values using standard string equality (String.equals()) rather than a constant-time comparison.
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.
