CVE-2015-10004 Timing side-channel in github.com/robbert229/jwt
Token validation methods are susceptible to a timing side-channel during HMAC comparison. With a large enough number of requests over a low latency connection, an attacker may use this to determine the expected HMAC...
Non-constant time HMAC comparison
Jenkins 2.218 and earlier, LTS 2.204.1 and earlier does not use a constant-time comparison when checking whether two HMACs are equal. This could potentially allow attackers to use statistical methods to obtain a valid HMAC for an attacker-controlled input value. Jenkins 2.219, LTS 2.204.2 now use...

CVE-2019-10071
The code which checks HMAC in form submissions used String.equals for comparisons, which results in a timing side channel for the comparison of the HMAC signatures. This could lead to remote code execution if an attacker is able to determine the correct signature for their payload. The comparison...
Timing Attack
django-debug-toolbar is vulnerable to timing attacks. The library is vulnerable because they do not compare HMACs in constant-time, which allows malicious users to use the timing of the request to progressively identify a valid HMAC hashes...
CVE-2016-5429
jose-php before 2.2.1 does not use constant-time operations for HMAC comparison, which makes it easier for remote attackers to obtain sensitive information via a timing attack, related to JWE.php and JWS.php...
CVE-2016-5429
CVE-2016-5429 concerns the jose-php library prior to 2.2.1, where non-constant-time HMAC comparisons in the implementation (notably in JWE.php and JWS.php) can enable remote attackers to glean sensitive data via timing attacks. Public sources consistently state that the vulnerability enables info...
