A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). A session identifier is generated using an algorithm with insufficient randomness, resulting in a token with low entropy that can be predicted or brute-forced within a feasible number of attempts. This could allow an unauthenticated remote attacker to derive valid session identifiers and bypass authentication.

Power System Insufficient Entropy
IBM PowerVM Hypervisor FW1110.00 through FW1110.20, FW1060.00 through FW1060.71, and FW950.00 through FW950.H2 could allow a local attacker with administrative privileges to decrypt encrypted data due to certain hypervisor calls utilizing less entropy than requested.

Power System Insufficient Entropy
IBM PowerVM Hypervisor Platform KeyStore (PKS) and virtual TPM FW1110.00 through FW1110.20, FW1060.00 through FW1060.71, and FW950.00 through FW950.H2 use persistent storage key seeds that result in an AES key with reduced strength. An attacker with access to the service processor or HMC could exploit this weakness to derive the encryption key and access the data.

CWE-331 Aug 7, 2026
crypto-js: Insufficient Entropy in Cryptographic Secret Generation via Vulnerable CryptoJS Dependency Chain
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.

osTicket 1.18.3 generates API keys using a predictable construction based on MD5 hashing. The use of MD5, combined with predictable inputs such as the current timestamp and client IP address, significantly reduces entropy. An attacker can approximate the key generation time and brute-force the key space within a feasible time window.

Nexus Repository Manager - Insufficient Entropy in Format-Specific API Key Generation
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.

Insufficient Entropy in Raspberry Pi 5 and Compute Module 5
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.

DPA Countermeasures weakening on Series 3 devices
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

Micca KE700 Brute-force vulnerability due to low entropy
The Micca KE700 system relies on a 6-bit portion of an identifier for authentication within rolling codes, providing only 64 possible combinations. This low entropy allows an attacker to perform a brute-force attack against one component of the rolling code. Successful exploitation simplify an attacker to predict the next valid rolling code, granting unauthorized access to the vehicle.
