CVE-2026-49212 Symfony UX: LiveComponentHydrator HMAC checksum lacks component and slot binding

Symfony UX is a JavaScript ecosystem for Symfony. From 2.8.0 until 2.36.0 and 3.1.0, the HMAC computed by Symfony\UX\LiveComponent\LiveComponentHydrator covered only sorted prop key/value pairs and did not include the component name, the slot identifier props vs propsFromParent, or request contex...

CVE-2026-9537

The Mojo::JWT Perl module, in versions before 1.02 , is vulnerable to a timing attack due to the use of a non-constant-time string comparison (Perl's eq operator) during HMAC signature verification. Specifically, the decode() method compares the supplied signature against the recomputed HMAC; bec...

CVE-2026-9537

Mojo::JWT versions before 1.02 for Perl verify HMAC signatures with a non-constant-time string comparison. The decode method compares the supplied signature to the recomputed HMAC with Perl's eq operator, which stops at the first differing byte, so the comparison time varies with the number of...

CVE-2026-49852: Improper Authentication

joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption JOSE standards. Prior to 1.6.8, joserfc.jwt.decode accepts attacker-forged HMAC-signed tokens when the caller-supplied verification key is the empty string or None, because HMACAlgorithm.sign...

SUSE CVE-2026-54736

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...

HMAC zero-length tag forgery in EVPDigestVerifyFinal, where a zero-length tag could be accepted as valid during HMAC verification. In the OpenSSL-compatibility HMAC verify path the supplied signature length was only checked as not exceeding the MAC length, so a zero-length or otherwise truncated...
