CVE-2026-905628.1 HIG36.3%
——11LangBot before 4.10.11 generates password recovery keys with only 24 bits of entropy and applies no rate limiting to the unauthenticated reset-password endpoint. Remote attackers knowing the administrator email can exhaust the keyspace through concurrent requests to reset the admin password and gain account access.7dCVE-2026-801714.7 MED0.4%
——0Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains an Insufficient Entropy in PRNG vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to elevation of privileges.13dCVE-2026-626467.4 HIG24.6%
——7A 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.12dCVE-2026-274907.5 HIG24.6%
——7Combodo 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 3.2.3.13dCVE-2026-49375.3 MED0.9%
——0IBM 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.28dCVE-2026-49365.1 MED0.1%
——0IBM 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.28d
