User Attribute Enumeration when Using DaoAuthenticationProvider

If an application is using the UserDetailsisEnabled , isAccountNonExpired , or isAccountNonLocked user attributes, to enable, expire, or lock users, then DaoAuthenticationProvider 's timing attack defense can be bypassed for users who are disabled, expired, or locked...

Kimai: Username enumeration via timing on X-AUTH-USER

Details src/API/Authentication/TokenAuthenticator.php calls loadUserByIdentifier first and only invokes the password hasher argon2id when a user is returned. When the username does not exist, the request returns roughly 25 ms faster than when it does. The response body is the same in both cases...

Timing Attack

Overview Affected versions of this package are vulnerable to Timing Attack via the TokenAuthenticator process. An attacker can determine valid usernames by measuring response time differences when submitting authentication requests with the X-AUTH-USER header. Remediation Upgrade kimai/kimai to...

GRUB Cryptographic memcmp Buffer Overflow DoS

The vulnerability of the grubcryptomemcmp function in the GNU GRUB formerly Grub2 operating system is related to the disclosure of information due to timing discrepancies. Exploiting this vulnerability could allow an attacker to compromise the confidentiality of the protected information...

CVE-2026-40263

Note Mark is an open-source note-taking application. In versions 0.19.1 and prior, the login endpoint performs bcrypt password verification only when the supplied username exists, returning immediately for nonexistent usernames. This timing discrepancy allows unauthenticated attackers to enumerat...

BIT-AUTHENTIK-2024-52307 authentik allows a timing attack due to missing constant time comparison for metrics view

authentik is an open-source identity provider. Due to the usage of a non-constant time comparison for the /-/metrics/ endpoint it was possible to brute-force the SECRETKEY, which is used to authenticate the endpoint. The /-/metrics/ endpoint returns Prometheus metrics and is not intended to be...

GHSA-WQQ3-WFMP-V85G Mojic: Observable Timing Discrepancy in HMAC Verification

Summary The CipherEngine in Mojic v2.1.3 uses a standard equality operator !== to verify the HMAC-SHA256 integrity seal during the decryption phase. This creates an Observable Timing Discrepancy CWE-208, allowing a potential attacker to bypass the file integrity check via a timing attack. Details...
