{"id":"CVE-2026-59276","summary":"Timing Attack via Non-Constant-Time Comparison of Sensitive Values","details":"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.\nSpring Security 7.1.0\nSpring Security 7.0.0 - 7.0.6\nSpring Security 6.5.0 - 6.5.11\nSpring Security 6.4.0 - 6.4.18\nSpring Security 5.8.0 - 5.8.27\nSpring Security 5.7.0 - 5.7.25","modified":"2026-09-04T03:47:36.016387677Z","published":"2026-08-27T17:57:34.993Z","database_specific":{"cna_assigner":"vmware","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59276.json","unresolved_ranges":[{"extracted_events":[{"introduced":"7.1.0"},{"last_affected":"7.1.0"},{"introduced":"7.0.0"},{"last_affected":"7.0.6"},{"introduced":"6.5.0"},{"last_affected":"6.5.11"},{"introduced":"6.4.0"},{"last_affected":"6.4.18"},{"introduced":"5.8.0"},{"last_affected":"5.8.27"},{"introduced":"5.7.0"},{"last_affected":"5.7.25"}],"source":"AFFECTED_FIELD"}]},"references":[{"type":"WEB","url":"https://spring.io/security/cve-2026-59276"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59276.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59276"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/spring-projects/spring-security","events":[{"introduced":"8078781a6bdbd0c44755d24e13839d041caece34"},{"fixed":"ab8b139278dc0649bab1f520fb2a78c7719d56f9"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:vmware:spring_security:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"7.1.0"},{"fixed":"7.1.0.1"}]}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-59276.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
