CVE-2025-67504 1 Wbce 1 Wbce Cms 2026-06-17 N/A 9.1 CRITICAL
WBCE CMS is a content management system. Versions 1.6.4 and below use function GenerateRandomPassword() to create passwords using PHP's rand(). rand() is not cryptographically secure, which allows password sequences to be predicted or brute-forced. This can lead to user account compromise or privilege escalation if these passwords are used for new accounts or password resets. The vulnerability is fixed in version 1.6.5.
CVE-2025-66565 1 Gofiber 1 Utils 2026-06-17 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-2025-62774 2026-06-17 N/A 3.1 LOW
On Mercku M6a devices through 2.1.0, the authentication system uses predictable session tokens based on timestamps.
CVE-2025-59015 1 Typo3 1 Typo3 2026-06-17 N/A 6.5 MEDIUM
A deterministic three‑character prefix in the Password Generation component of TYPO3 CMS versions 12.0.0–12.4.36 and 13.0.0–13.4.17 reduces entropy, allowing attackers to carry out brute‑force attacks more quickly.
CVE-2025-54885 2026-06-17 N/A N/A
Thinbus Javascript Secure Remote Password is a browser SRP6a implementation for zero-knowledge password authentication. In versions 2.0.0 and below, a protocol compliance bug causes the client to generate a fixed 252 bits of entropy instead of the intended bit length of the safe prime (defaulted to 2048 bits). The client public value is being generated from a private value that is 4 bits below the specification. This reduces the protocol's designed security margin it is now practically exploitable. The servers full sized 2048 bit random number is used to create the shared session key and password proof. This is fixed in version 2.0.1.
CVE-2025-52464 1 Meshtastic 1 Meshtastic Firmware 2026-06-17 N/A 8.3 HIGH
Meshtastic is an open source mesh networking solution. In versions from 2.5.0 to before 2.6.11, the flashing procedure of several hardware vendors was resulting in duplicated public/private keys. Additionally, the Meshtastic was failing to properly initialize the internal randomness pool on some platforms, leading to possible low-entropy key generation. When users with an affected key pair sent Direct Messages, those message could be captured and decrypted by an attacker that has compiled the list of compromised keys. This issue has been patched in version 2.6.11 where key generation is delayed til the first time the LoRa region is set, along with warning users when a compromised key is detected. Version 2.6.12 furthers this patch by automatically wiping known compromised keys when found. A workaround to this vulnerability involves users doing a complete device wipe to remove vendor-cloned keys.
CVE-2025-50122 2026-06-17 N/A N/A
A CWE-331: Insufficient Entropy vulnerability exists that could cause root password discovery when the password generation algorithm is reverse engineered with access to installation or upgrade artifacts.
CVE-2025-47781 1 Rallly 1 Rallly 2026-06-17 N/A 9.8 CRITICAL
Rallly is an open-source scheduling and collaboration tool. Versions up to and including 3.22.1 of the application features token based authentication. When a user attempts to login to the application, they insert their email and a 6 digit code is sent to their email address to complete the authentication. A token that consists of 6 digits only presents weak entropy however and when coupled with no token brute force protection, makes it possible for an unauthenticated attacker with knowledge of a valid email address to successfully brute force the token within 15 minutes (token expiration time) and take over the account associated with the targeted email address. All users on the Rallly applications are impacted. As long as an attacker knows the user's email address they used to register on the app, they can systematically take over any user account. For the authentication mechanism to be safe, the token would need to be assigned a complex high entropy value that cannot be bruteforced within reasonable time, and ideally rate limiting the /api/auth/callback/email endpoint to further make brute force attempts unreasonable within the 15 minutes time. As of time of publication, no patched versions are available.
CVE-2025-32898 2026-06-17 N/A 4.7 MEDIUM
The KDE Connect verification-code protocol before 2025-04-18 uses only 8 characters and therefore allows brute-force attacks. This affects KDE Connect before 1.33.0 on Android, KDE Connect before 25.04 on desktop, KDE Connect before 0.5 on iOS, Valent before 1.0.0.alpha.47, and GSConnect before 59.
CVE-2025-2814 2026-06-17 N/A 4.0 MEDIUM
Crypt::CBC versions between 1.21 and 3.05 for Perl may use the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. This issue affects operating systems where "/dev/urandom'" is unavailable.  In that case, Crypt::CBC will fallback to use the insecure rand() function.
CVE-2025-29311 1 Opennetworking 1 Onos 2026-06-17 N/A 7.5 HIGH
Limited secret space in LLDP packets used in onos v2.7.0 allows attackers to obtain the private key via a bruteforce attack. Attackers are able to leverage this vulnerability into creating crafted LLDP packets.
CVE-2025-27552 2026-06-17 N/A 4.0 MEDIUM
DBIx::Class::EncodedColumn use the rand() function, which is not cryptographically secure to salt password hashes. This vulnerability is associated with program files Crypt/Eksblowfish/Bcrypt.pm. This issue affects DBIx::Class::EncodedColumn until 0.00032.
CVE-2025-27551 2026-06-17 N/A 4.0 MEDIUM
DBIx::Class::EncodedColumn use the rand() function, which is not cryptographically secure to salt password hashes. This vulnerability is associated with program files lib/DBIx/Class/EncodedColumn/Digest.pm. This issue affects DBIx::Class::EncodedColumn until 0.00032.
CVE-2025-1860 2026-06-17 N/A 7.7 HIGH
Data::Entropy for Perl 0.007 and earlier use the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
CVE-2025-1828 1 Timlegge 1 Crypt\ 2026-06-17 N/A 8.8 HIGH
Crypt::Random Perl package 1.05 through 1.55 may use rand() function, which is not cryptographically strong, for cryptographic functions. If the Provider is not specified and /dev/urandom or an Entropy Gathering Daemon (egd) service is not available Crypt::Random will default to use the insecure Crypt::Random::rand provider. In particular, Windows versions of perl will encounter this issue by default.
CVE-2025-15387 2026-06-17 N/A 8.8 HIGH
VPN Firewall developed by QNO Technology has a Insufficient Entropy vulnerability, allowing unauthenticated remote attackers to obtain any logged-in user session through brute-force attacks and subsequently log into the system.
CVE-2025-14972 2026-06-17 N/A N/A
* Countermeasures for DPA within SYMCRYPTO engine on SixG301xxx devices are not sufficiently random and will eventually repeat. * KSU keys using SYMCRYPTO will be impacted by this vulnerability.
CVE-2025-14261 2026-06-17 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.
CVE-2025-13399 1 Tp-link 2 Vx800v, Vx800v Firmware 2026-06-17 N/A 8.8 HIGH
A weakness in the web interface’s application layer encryption in VX800v v1.0 allows an adjacent attacker to brute force the weak AES key and decrypt intercepted traffic. Successful exploitation requires network proximity but no authentication, and may result in high impact to confidentiality, integrity, and availability of transmitted data.
CVE-2025-0577 2026-06-17 N/A 4.8 MEDIUM
An insufficient entropy vulnerability was found in glibc. The getrandom and arc4random family of functions may return predictable randomness if these functions are called again after the fork, which happens concurrently with a call to any of these functions.
