tomcat: Apache Tomcat: Information disclosure via AJP secret timing discrepancy

A flaw was found in Apache Tomcat. The AJP secret was comparable in non-constant time, allowing an attacker on the local network to mount a timing attack to determine the AJP secret, which may lead to unauthorized access or other security bypasses...

crypto/internal/nistec: golang: Timing sidechannel for P-256 on ppc64le in crypto/internal/nistec

A flaw was found in the Golang crypto/internal/nistec package. Due to the usage of a variable time instruction in the assembly implementation of an internal function, a small number of bits of secret scalars are leaked on the ppc64le architecture. Considering how this function is used, this leaka...

K000163349: Gnutls vulnerability CVE-2026-5419

Security Advisory Description A flaw was found in gnutls. The PKCS7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. Th...

apr-util: Apache Portable Runtime Utility: Information disclosure via timing attack in password validation

A flaw was found in Apache Portable Runtime Utility apr-util. The aprpasswordvalidate function does not perform constant-time comparisons for hashes or passwords. This vulnerability allows a remote attacker to conduct a timing attack, particularly on platforms without crypt such as Windows, BeOS,...

PT-2026-96163

Name of the Vulnerable Software and Affected Versions Tinyauth versions prior to 5.1.0 Description Tinyauth exposes a timing difference during authentication attempts that allows a remote observer to distinguish between existing and nonexistent local usernames. This occurs because the loginHandle...

CVE-2026-58272: Observable Timing Discrepancy

Sync-in Server is an open-source platform for file storage, sharing, collaboration, and syncing. Versions prior to 2.4.1 contain an observable timing discrepancy in the login endpoint because authentication attempts for nonexistent accounts return without performing the bcrypt comparison used for...
