CVE-2026-55785

free5GC's AUSF component (prior to version 1.4.5) performs 5G-AKA cryptographic authentication comparisons in ue_authentication.go using non-constant-time helpers: strings.EqualFold for RES*/XRES* and bytes.Equal for AT_MAC/XMAC. Additionally, the expected XRES* value is logged at INFO level befo...

CVE-2026-59276

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...

CVE-2026-59276 Timing Attack via Non-Constant-Time Comparison of Sensitive Values

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...

CVE-2026-59276

Spring Security is affected by a timing attack vulnerability in several components that compare security-sensitive values using standard String.equals() instead of a constant-time comparison. Because String.equals() returns as soon as a differing character is found, the response time for rejectin...

CVE-2026-72700

The getgrav/grav-plugin-login Composer plugin before 3.9.1 used by Grav compares password reset and account activation tokens using a non-constant-time === string comparison instead of hashequals in classes/Controller.php taskReset and login.php activation handler. Because the token-submission...

CVE-2026-72700 Grav before 3.9.1 Timing Attack via Non-Constant-Time Token Comparison

The getgrav/grav-plugin-login Composer plugin before 3.9.1 used by Grav compares password reset and account activation tokens using a non-constant-time === string comparison instead of hashequals in classes/Controller.php taskReset and login.php activation handler. Because the token-submission...

CVE-2026-72701: Observable Timing Discrepancy

Grav CMS before 2.0.16 contains a timing vulnerability in Utils::verifyNonce that uses non-constant-time string comparison with the === operator instead of hashequals for CSRF nonce validation. Attackers can measure response timing differences to recover valid nonce values byte-by-byte through...
