A privilege escalation vulnerability in Microchip IStaX allows an authenticated low-privileged user to recover a shared per-device cookie secret from their own webstax_auth session cookie and forge a new cookie with administrative privileges.This issue affects IStaX before 2026.03.
CVE-2026-34236 1 Auth0 1 Auth0-php 2026-10-26 N/A 8.2 HIGH
Auth0-PHP is a PHP SDK for Auth0 Authentication and Management APIs. From version 8.0.0 to before version 8.19.0, in applications built with the Auth0 PHP SDK, cookies are encrypted with insufficient entropy, which may result in threat actors brute-forcing the encryption key and forging session cookies. This issue has been patched in version 8.19.0.
CVE-2026-4827 2026-10-26 N/A N/A
CWE‑331: Insufficient Entropy vulnerability exists that could lead to unauthorized access when an attacker on the network can exploit weaknesses in session‑management protections.
CVE-2026-7210 1 Python 1 Python 2026-10-26 N/A 7.5 HIGH
`xml.parsers.expat` and `xml.etree.ElementTree` use insufficient entropy for Expat hash-flooding protection, which allows a crafted XML document to trigger hash flooding.\r\n\r\nFully mitigating this vulnerability requires both updating libexpat to 2.8.0 or later and applying this patch.
CVE-2026-42155 2026-10-26 N/A N/A
Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the Magento Community Edition e-commerce platform with a high level of backward compatibility. Prior to 20.18.0, the XML-RPC / SOAP API session ID is generated using an outdated, time-based construction rather than a Cryptographically Secure Pseudo-Random Number Generator (CSPRNG). All inputs to the MD5 hash are time-derived and non-secure. Because the resulting digest relies entirely on the timestamp and the PHP internal LCG state, the effective entropy is severely constrained. This violates the OWASP ASVS v4 requirement of ≥ 64 bits of entropy (V3.2.2) and NIST SP 800-63B standards. By narrowing the LCG window (via server state leaks or general predictability) and leveraging the lack of API rate-limiting, an attacker can generate a localized pool of candidate MD5 hashes and execute a high-speed online brute-force attack to hijack active API sessions. This vulnerability is fixed in 20.18.0.
CVE-2026-46474 2026-10-26 N/A 7.5 HIGH
Trog::TOTP versions before 1.006 for Perl generate secrets using rand. Secrets were generated using Perl's built-in rand function, which is predictable and unsuitable for security usage.
CVE-2026-8700 2026-10-26 N/A 7.3 HIGH
Crypt::DSA versions before 1.20 for Perl generate seeds using rand. Seeds were generated using Perl's built-in rand function, which is predictable and unsuitable for security usage.
CVE-2026-4930 2026-10-25 N/A N/A
SYMCRYPTO is the SiXG301's host side hardware engine accessed by PSA crypto library that accelerates symmetric cryptographic operations (AES encryption/decryption and hashing). DPA Countermeasures on SYMCRYPTO can be weakened (reduced entropy) by forcing certain seed values if an attacker gains code execution capability on the impacted device. * Therefore, the keys loaded on SYMCRYPTO may be more vulnerable to extraction through DPA attacks than intended
CVE-2026-13199 2026-10-25 N/A 4.0 MEDIUM
EEPROM firmware on Raspberry Pi 5 and Compute Module 5 devices produced non-random KASLR and RNG seed values. This resulted in consistent kernel addresses across boots and devices, potentially making it easier to exploit other vulnerabilities. Additionally, the low-quality RNG seed may affect the quality of random numbers or delay booting while sufficient entropy is accumulated from other sources.
CVE-2026-11403 1 Sonatype 1 Nexus Repository Manager 2026-10-24 N/A 7.5 HIGH
A vulnerability in Sonatype Nexus Repository Manager's format-specific API key generation may allow a remote attacker to gain unauthorized access to repository operations as a targeted user. A format-specific API key realm (NuGet API Key, Docker Bearer Token, or npm Bearer Token) must be enabled and the targeted user must have an active API key for this vulnerability to be exploitable.
CVE-2026-71851 2026-10-24 N/A 9.0 CRITICAL
crypto-js is a JavaScript library of crypto standards. Versions of crypto-js prior to 4.0.0 generate randomness in CryptoJS.lib.WordArray.random() using a custom variation of the Multiply-With-Carry pseudorandom number generator, seeded from Math.random(), instead of a cryptographically secure source. This generator was introduced in version 3.1.2-4 and remained present in nearly every 3.x release. Nominal requests for 128 or 256 bits of entropy through this function produce effective search spaces of approximately 2 to the 39th and 2 to the 47th possibilities, small enough to enumerate on commodity hardware. Downstream wallet applications that used CryptoJS.lib.WordArray.random() as the entropy source for BIP39 recovery phrases are affected, and an attacker who enumerates the reduced output space can recover the resulting private keys and control the associated funds. This issue is fixed in version 4.0.0.
CVE-2026-4932 1 Ibm 34 Power System E1050 \(9043-mrx\), Power System E1050 \(9043-mrx\) Firmware, Power System E1080 \(9080-hex\) and 31 more 2026-10-23 N/A 4.2 MEDIUM
IBM PowerVM Hypervisor FW1110.00 through FW1110.20, and FW1060.00 through FW1060.71 could allow an attacker with physical access to the Transparent Memory Encryption (TME) hardware to decrypt encrypted memory due to insufficient cryptographic entropy.
CVE-2026-92209 2026-10-23 N/A 7.8 HIGH
NoMachine Redis Improper Authentication Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of NoMachine. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the authentication mechanism controlling access to the Redis database. The issue results from using insufficient entropy in the generation of credentials. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the service account. Was ZDI-CAN-30984.

CVE-2026-27490 2026-10-14 N/A 7.5 HIGH
Combodo iTop is a web based IT service management tool. Prior to 3.2.3, inline images that are accessible without being authenticated are protected by a weak 24-bit pseudo-random secret. This issue has been fixed in version 3.2.3.
CVE-2019-15847 2 Gnu, Opensuse 2 Gcc, Leap 2026-10-14 5.0 MEDIUM 7.5 HIGH
The POWER9 backend in GNU Compiler Collection (GCC) before version 10 could optimize multiple calls of the __builtin_darn intrinsic into a single call, thus reducing the entropy of the random number generator. This occurred because a volatile operation was not specified. For example, within a single execution of a program, the output of every __builtin_darn() call may be the same.
CVE-2025-62774 2026-10-08 N/A 3.1 LOW
On Mercku M6a devices through 2.1.0, the authentication system uses predictable session tokens based on timestamps.
CVE-2015-8851 1 Node-uuid Project 1 Node-uuid 2026-10-07 5.0 MEDIUM 7.5 HIGH
node-uuid before 1.4.4 uses insufficiently random data to create a GUID, which could make it easier for attackers to have unspecified impact via brute force guessing.
CVE-2025-66565 1 Gofiber 1 Utils 2026-10-07 N/A 9.8 CRITICAL
Fiber Utils is a collection of common functions created for Fiber. In versions 2.0.0-rc.3 and below, when the system's cryptographic random number generator (crypto/rand) fails, both functions silently fall back to returning predictable UUID values, including the zero UUID "00000000-0000-0000-0000-000000000000". The vulnerability occurs through two related but distinct failure paths, both ultimately caused by crypto/rand.Read() failures, compromising the security of all Fiber applications using these functions for security-critical operations. This issue is fixed in version 2.0.0-rc.4.
CVE-2025-14261 2026-10-07 N/A 7.1 HIGH
The Litmus platform uses JWT for authentication and authorization, but the secret being used for signing the JWT is only 6 bytes long at its core, which makes it extremely easy to crack.
