CVE-2026-54736: Observable Timing Discrepancy

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...

CVE-2026-59218 Open WebUI: Account enumeration via observable login timing discrepancy

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, the /api/v1/auths/signin endpoint looked users up by email and only ran bcrypt password verification when a credential existed, making registered-account attempts measurably slower than...

CVE-2026-15041: Observable Timing Discrepancy

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...

CVE-2026-41515: Observable Timing Discrepancy

OP-TEE is a Trusted Execution Environment TEE designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. Starting in version 3.9.0 and prior to version 4.11.0, the RSA-OAEP decryption implementation in the NXP CAAM crypto driver uses...

K000162052: Apache Tomcat vulnerability CVE-2026-43514

Security Advisory Description Observable Timing Discrepancy vulnerability when comparing AJP secret in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.21, from 10.1.0-M1 through 10.1.54, from 9.0.0.M1 through 9.0.117, from 8.5.0 through 8.5.100, from 7.0.0 through...

CVE-2026-13758: Observable Timing Discrepancy

CryptX versions before 0.088001 for Perl compare AEAD authentication tags in non-constant time in the streaming decryptdone path. The decryptdone$tag form compares it against the computed tag with memNE memcmp != 0, which short-circuits on the first differing byte, so its run time depends on the...

CVE-2026-47380: Observable Timing Discrepancy

NocoDB is software for building databases as spreadsheets. Prior to 2026.04.1, sign-in response timing differed between known and unknown email addresses because the unknown-user branch returned without performing a password hash comparison. This vulnerability is fixed in 2026.04.1...

CVE-2026-48166: Observable Timing Discrepancy

Filament is a collection of full-stack components for accelerated Laravel development. From 4.0.0 until 4.11.5 and 5.6.5, the login page has an observable timing discrepancy that allows unauthenticated attackers to enumerate registered email addresses. The impact is limited to disclosing whether ...
