Generating the ECDSA nonce k samples a random number r and then truncates this randomness with a modular reduction mod n where n is the order of the elliptic curve. Meaning k = r mod n. The division used during the reduction estimates a factor qe by dividing the upper two digits a digit having e....

Multiple constant-time implementations in wolfSSL before version 5.8.4 may be transformed into non-constant-time binary by LLVM optimizations, which can potentially result in observable timing discrepancies and lead to information disclosure through timing side-channel attacks...

PYSEC-2026-3028 pyquorum: Timing side‑channel in mul_mod

Impact The mulmod function implements multiplication via a binary expansion loop whose execution time depends on the Hamming weight of the second operand the exponent. An attacker who can measure the time of secret‑sharing operations e.g., via a remote service could progressively recover the valu...

CVE-2026-54736 Phalcon: Non-constant-time HMAC verification in `Encryption\Crypt::decrypt` (timing side-channel)

Phalcon is a high-performance, full-stack PHP framework. Prior to 5.14.1, Phalcon\Encryption\Crypt::decrypt compares the attacker-supplied HMAC tag against the freshly computed HMAC using PHP/Zephir identity comparison, which lowers to a byte-wise comparison that returns early on the first...

PT-2026-57320

Name of the Vulnerable Software and Affected Versions Phalcon versions prior to 5.14.1 Description The decrypt function within PhalconEncryptionCrypt uses a byte-wise identity comparison to verify the HMAC tag. Because this comparison returns early upon encountering the first differing byte, it...

UBUNTU-CVE-2026-15041

A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password verification function uses standard memcmp for comparing password hashes instead of a constant-time comparison function. A remote attacker could potentially use timing measurements of LDAP bind attempts to infer partial hash...

PYSEC-2026-1716 OctoPrint has Timing Side-Channel Vulnerability in API Key Authentication

Impact OctoPrint versions up to and including 1.11.5 are affected by a theoretical timing attack vulnerability that allows API key extraction over the network. Due to using character based comparison that short-circuits on the first mismatched character during API key validation, rather than a...

PYSEC-2026-1066 wolfCrypt leaks cryptographic information via timing side channel

wolfSSL and wolfCrypt 4.0.0 and earlier when configured without --enable-fpecc, --enable-sp, or --enable-sp-math contain a timing side channel in ECDSA signature generation. This allows a local attacker, able to precisely measure the duration of signature operations, to infer information about th...
