CVE-2023-2884 1 Cbot 2 Cbot Core, Cbot Panel 2026-05-22 9.8 Critical
Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG), Use of Insufficiently Random Values vulnerability in CBOT Chatbot allows Signature Spoofing by Key Recreation. This issue affects Chatbot: before Core: v4.0.3.4 Panel: v4.0.3.7.
CVE-2026-44054 1 Netatalk 1 Netatalk 2026-05-21 6.5 Medium
Netatalk 2.0.0 through 4.4.2 generates AFP session tokens derived from predictable process IDs, which allows a remote authenticated attacker to cause a denial of service by exploiting the reconnect mechanism.
CVE-2019-11840 3 Debian, Golang, Redhat 3 Debian Linux, Crypto, Openshift 2026-05-18 5.9 Medium
An issue was discovered in the supplementary Go cryptography library, golang.org/x/crypto, before v0.0.0-20190320223903-b7391e95e576. A flaw was found in the amd64 implementation of the golang.org/x/crypto/salsa20 and golang.org/x/crypto/salsa20/salsa packages. If more than 256 GiB of keystream is generated, or if the counter otherwise grows greater than 32 bits, the amd64 implementation will first generate incorrect output, and then cycle back to previously generated keystream. Repeated keystream bytes can lead to loss of confidentiality in encryption applications, or to predictability in CSPRNG applications.
CVE-2026-42155 1 Openmage 1 Magento 2026-05-17 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 Prior to 20.18.0, the XML-RPC / SOAP API session ID is generated using an outdated, time-based construction rather than a Cryptographically Secure Pseudo-Random Number Generator (CSPRNG).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-2026-41505 1 Inducer 1 Relate 2026-05-07 8.7 High
RELATE is a web-based courseware package. Prior to commit 2f68e16, RELATE is vulnerable to predictable token generation in auth.py's make_sign_in_key() function and exam.py's gen_ticket_code() function. This issue has been patched via commit 2f68e16.
CVE-2026-7847 1 Chatchat-space 1 Langchain-chatchat 2026-05-06 2.6 Low
A vulnerability was found in chatchat-space Langchain-Chatchat up to 0.3.1.3. The affected element is the function _get_file_id of the file libs/chatchat-server/chatchat/server/api_server/openai_routes.py of the component Uploaded File Handler. Performing a manipulation results in insufficiently random values. Access to the local network is required for this attack. The attack's complexity is rated as high. The exploitability is described as difficult. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-40975 2 Spring, Vmware 2 Spring Boot, Spring Boot 2026-04-30 4.8 Medium
Values produced by ${random.value} are not suitable for use as secrets. ${random.uuid} is not affected. ${random.int} and ${random.long} should never be used for secrets as they are numeric values with a predictable range. Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); random value property source / weak PRNG for secrets. Versions that are no longer supported are also affected per vendor advisory.
CVE-2026-40306 1 Dnnsoftware 2 Dnn Platform, Dotnetnuke 2026-04-24 6.5 Medium
DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. All new installations of DNN 10.x.x - 10.2.1 have the same Host GUID. This does not affect upgrades from 9.x.x. Version 10.2.2 patches the issue.
CVE-2026-40496 2 Freescout, Freescout Helpdesk 2 Freescout, Freescout 2026-04-23 9.1 Critical
FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.213, attachment download tokens are generated using a weak and predictable formula: `md5(APP_KEY + attachment_id + size)`. Since attachment_id is sequential and size can be brute-forced in a small range, an unauthenticated attacker can forge valid tokens and download any private attachment without credentials. Version 1.8.213 fixes the issue.
CVE-2008-4905 1 Typosphere 1 Typo 2026-04-23 7.5 High
Typo 5.1.3 and earlier uses a hard-coded salt for calculating password hashes, which makes it easier for attackers to guess passwords via a brute force attack.
CVE-2009-3238 5 Canonical, Linux, Opensuse and 2 more 7 Ubuntu Linux, Linux Kernel, Opensuse and 4 more 2026-04-23 5.5 Medium
The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function's tendency to "return the same value over and over again for long stretches of time."
CVE-2009-0255 2 Debian, Typo3 2 Debian Linux, Typo3 2026-04-23 7.5 High
The System extension Install tool in TYPO3 4.0.0 through 4.0.9, 4.1.0 through 4.1.7, and 4.2.0 through 4.2.3 creates the encryption key with an insufficiently random seed, which makes it easier for attackers to crack the key.
CVE-2008-4929 1 Mybb 1 Mybb 2026-04-23 7.5 High
MyBB (aka MyBulletinBoard) 1.4.2 uses insufficient randomness to compose filenames of uploaded files used as attachments, which makes it easier for remote attackers to read these files by guessing filenames.
CVE-2008-2433 1 Trendmicro 3 Client Server Messaging Suite, Officescan, Worry-free Business Security 2026-04-23 9.8 Critical
The web management console in Trend Micro OfficeScan 7.0 through 8.0, Worry-Free Business Security 5.0, and Client/Server/Messaging Suite 3.5 and 3.6 creates a random session token based only on the login time, which makes it easier for remote attackers to hijack sessions via brute-force attacks. NOTE: this can be leveraged for code execution through an unspecified "manipulation of the configuration."
CVE-2009-2158 1 Torrenttrader Project 1 Torrenttrader 2026-04-23 7.5 High
account-recover.php in TorrentTrader Classic 1.09 chooses random passwords from an insufficiently large set, which makes it easier for remote attackers to obtain a password via a brute-force attack.
CVE-2008-0087 1 Microsoft 4 Windows 2000, Windows Server 2003, Windows Vista and 1 more 2026-04-23 7.5 High
The DNS client in Microsoft Windows 2000 SP4, XP SP2, Server 2003 SP1 and SP2, and Vista uses predictable DNS transaction IDs, which allows remote attackers to spoof DNS responses.
CVE-2008-3612 1 Apple 1 Iphone Os 2026-04-23 9.8 Critical
The Networking subsystem in Apple iPod touch 2.0 through 2.0.2, and iPhone 2.0 through 2.0.2, uses predictable TCP initial sequence numbers, which allows remote attackers to spoof or hijack a TCP connection.
CVE-2008-0141 1 Webportal Cms Project 1 Webportal Cms 2026-04-23 7.5 High
actions.php in WebPortal CMS 0.6-beta generates predictable passwords containing only the time of day, which makes it easier for remote attackers to obtain access to any account via a lostpass action.
CVE-2008-2020 8 E107, Labgab, My123tkshop and 5 more 8 E107, Labgab, E-commerce-suite and 5 more 2026-04-23 7.5 High
The CAPTCHA implementation as used in (1) Francisco Burzi PHP-Nuke 7.0 and 8.1, (2) my123tkShop e-Commerce-Suite (aka 123tkShop) 0.9.1, (3) phpMyBitTorrent 1.2.2, (4) TorrentFlux 2.3, (5) e107 0.7.11, (6) WebZE 0.5.9, (7) Open Media Collectors Database (aka OpenDb) 1.5.0b4, and (8) Labgab 1.1 uses a code_bg.jpg background image and the PHP ImageString function in a way that produces an insufficient number of different images, which allows remote attackers to pass the CAPTCHA test via an automated attack using a table of all possible image checksums and their corresponding digit strings.
CVE-2008-5162 1 Freebsd 1 Freebsd 2026-04-23 7.0 High
The arc4random function in the kernel in FreeBSD 6.3 through 7.1 does not have a proper entropy source for a short time period immediately after boot, which makes it easier for attackers to predict the function's return values and conduct certain attacks against the GEOM framework and various network protocols, related to the Yarrow random number generator.
