CVE-2025-66511 1 Nextcloud 1 Calendar 2025-12-10 4.8 Medium
Nextcloud Calendar is a calendar app for Nextcloud. Prior to 6.0.3, the Calendar app generates participant tokens for meeting proposals using a hash function, allowing an attacker to compute valid participant tokens, which allowed them to request details and submit dates in meeting proposals. The tokens are not purely random generated. This vulnerability is fixed in 6.0.3.
CVE-2025-7394 1 Wolfssl 1 Wolfssl 2025-12-03 9.8 Critical
In the OpenSSL compatibility layer implementation, the function RAND_poll() was not behaving as expected and leading to the potential for predictable values returned from RAND_bytes() after fork() is called. This can lead to weak or predictable random numbers generated in applications that are both using RAND_bytes() and doing fork() operations. This only affects applications explicitly calling RAND_bytes() after fork() and does not affect any internal TLS operations. Although RAND_bytes() documentation in OpenSSL calls out not being safe for use with fork() without first calling RAND_poll(), an additional code change was also made in wolfSSL to make RAND_bytes() behave similar to OpenSSL after a fork() call without calling RAND_poll(). Now the Hash-DRBG used gets reseeded after detecting running in a new process. If making use of RAND_bytes() and calling fork() we recommend updating to the latest version of wolfSSL. Thanks to Per Allansson from Appgate for the report.
CVE-2024-23688 1 Consensys 1 Discovery 2025-11-29 5.3 Medium
Consensys Discovery versions less than 0.4.5 uses the same AES/GCM nonce for the entire session. which should ideally be unique for every message. The node's private key isn't compromised, only the session key generated for specific peer communication is exposed.
CVE-2023-30797 1 Netflix 1 Lemur 2025-11-21 7.5 High
Netflix Lemur before version 1.3.2 used insufficiently random values when generating default credentials. The insufficiently random values may allow an attacker to guess the credentials and gain access to resources managed by Lemur.
CVE-2024-10082 1 Ericsson 1 Codechecker 2025-11-14 8.7 High
CodeChecker is an analyzer tooling, defect database and viewer extension for the Clang Static Analyzer and Clang Tidy. Authentication method confusion allows logging in as the built-in root user from an external service. The built-in root user up until 6.24.1 is generated in a weak manner, cannot be disabled, and has universal access.This vulnerability allows an attacker who can create an account on an enabled external authentication service, to log in as the root user, and access and control everything that can be controlled via the web interface. The attacker needs to acquire the username of the root user to be successful. This issue affects CodeChecker: through 6.24.1.
CVE-2024-57868 1 Lev 1 Web\ 2025-11-13 5.5 Medium
Web::API 2.8 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. Specifically Web::API uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.
CVE-2024-52322 1 Localshop 1 Webservice\ 2025-11-13 5.5 Medium
WebService::Xero 0.11 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. Specifically WebService::Xero uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.
CVE-2025-47781 1 Rallly 1 Rallly 2025-11-06 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-2024-36048 2 Fedoraproject, Qt 3 Fedora, Qt, Qt Network Authorization 2025-11-04 9.8 Critical
QAbstractOAuth in Qt Network Authorization in Qt before 5.15.17, 6.x before 6.2.13, 6.3.x through 6.5.x before 6.5.6, and 6.6.x through 6.7.x before 6.7.1 uses only the time to seed the PRNG, which may result in guessable values.
CVE-2024-31497 6 Fedoraproject, Filezilla-project, Putty and 3 more 6 Fedora, Filezilla Client, Putty and 3 more 2025-11-04 5.9 Medium
In PuTTY 0.68 through 0.80 before 0.81, biased ECDSA nonce generation allows an attacker to recover a user's NIST P-521 secret key via a quick attack in approximately 60 signatures. This is especially important in a scenario where an adversary is able to read messages signed by PuTTY or Pageant. The required set of signed messages may be publicly readable because they are stored in a public Git service that supports use of SSH for commit signing, and the signatures were made by Pageant through an agent-forwarding mechanism. In other words, an adversary may already have enough signature information to compromise a victim's private key, even if there is no further use of vulnerable PuTTY versions. After a key compromise, an adversary may be able to conduct supply-chain attacks on software maintained in Git. A second, independent scenario is that the adversary is an operator of an SSH server to which the victim authenticates (for remote login or file copy), even though this server is not fully trusted by the victim, and the victim uses the same private key for SSH connections to other services operated by other entities. Here, the rogue server operator (who would otherwise have no way to determine the victim's private key) can derive the victim's private key, and then use it for unauthorized access to those other services. If the other services include Git services, then again it may be possible to conduct supply-chain attacks on software maintained in Git. This also affects, for example, FileZilla before 3.67.0, WinSCP before 6.3.3, TortoiseGit before 2.15.0.1, and TortoiseSVN through 1.14.6.
CVE-2024-25389 1 Rt-thread 1 Rt-thread 2025-11-04 7.5 High
RT-Thread through 5.0.2 generates random numbers with a weak algorithm of "seed = 214013L * seed + 2531011L; return (seed >> 16) & 0x7FFF;" in calc_random in drivers/misc/rt_random.c.

Broadcom RAID Controller web interface is vulnerable to insufficient randomness due to improper use of ssl.rnd to setup CIM connection
CVE-2024-53702 1 Sonicwall 11 Sma100 Firmware, Sma 200, Sma 200 Firmware and 8 more 2025-11-04 5.3 Medium
Use of cryptographically weak pseudo-random number generator (PRNG) vulnerability in the SonicWall SMA100 SSLVPN backup code generator that, in certain cases, can be predicted by an attacker, potentially exposing the generated secret.
CVE-2024-47945 2 Rittal, Rittal Gmbh And Co.kg 5 Cmc Iii Processing Units, Cmc Iii Processing Units Firmware, Iot Interface and 2 more 2025-11-03 9.1 Critical
The devices are vulnerable to session hijacking due to insufficient entropy in its session ID generation algorithm. The session IDs are predictable, with only 32,768 possible values per user, which allows attackers to pre-generate valid session IDs, leading to unauthorized access to user sessions. This is not only due to the use of an (insecure) rand() function call but also because of missing initialization via srand(). As a result only the PIDs are effectively used as seed.
CVE-2025-0218 1 Pgadmin 1 Pgagent 2025-11-03 5.5 Medium
When batch jobs are executed by pgAgent, a script is created in a temporary directory and then executed. In versions of pgAgent prior to 4.2.3, an insufficiently seeded random number generator is used when generating the directory name, leading to the possibility for a local attacker to pre-create the directory and thus prevent pgAgent from executing jobs, disrupting scheduled tasks.
