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...

CVE-2026-40194

A flaw was found in phpseclib, a PHP secure communications library. This vulnerability involves a timing attack where the comparison of Secure Shell SSH packet integrity checks HMACs takes a variable amount of time. A remote attacker could exploit this timing difference to deduce information abou...

Node.js: Node.js: Information disclosure via timing oracle in HMAC verification

A flaw was found in Node.js. The HMAC Hash-based Message Authentication Code verification process uses a comparison method that does not take a constant amount of time. This non-constant-time comparison can leak timing information, which, under specific conditions where precise timing measurement...

OpenClaw HMAC Data Compromise

The vulnerability of the HMAC-based Message Authentication Code algorithm used by the AI agent OpenClaw formerly known as ClawdBot or MoltBot relates to the possibility of bypassing the authentication process. Exploiting this vulnerability could allow a malicious actor to compromise the integrity...

EUVD-2026-21565

Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, REST API keys are generated using md5time + userid 5 - rand10000, 10000. The rand10000, 10000 call always returns exactly 10000 min == max, making the formula effectively md5timestamp + userid5 - 10000. An attacker who...

CVE-2025-15618

Business::OnlinePayment::StoredTransaction versions through 0.01 for Perl uses an insecure secret key. Business::OnlinePayment::StoredTransaction generates a secret key by using a MD5 hash of a single call to the built-in rand function, which is unsuitable for cryptographic use. This key is...

CVE-2026-3256 HTTP::Session versions before 0.54 for Perl defaults to using insecurely generated session ids

HTTP::Session versions before 0.54 for Perl defaults to using insecurely generated session ids. HTTP::Session defaults to using HTTP::Session::ID::SHA1 to generate session ids using a SHA-1 hash seeded with the built-in rand function, the high resolution epoch time, and the PID. The PID will come...
