CVE-2026-59276
mediumpriority · track · 0EPSS 0.003 · 26 %ileDEFRUSEPSS · scored 2026-10-27
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.
