nanoid: nanoid: Predictable ID generation due to integer overflow

A flaw was found in nanoid, a JavaScript library for generating unique string IDs. A remote attacker could exploit an integer overflow vulnerability by providing a specific input to the nanoidsize function. This issue causes the internal random number generator to become predictable, leading to t...

CVE-2026-41701

A flaw was found in Spring AMQP. The system generates predictable correlation identifiers IDs for message replies due to an internal simple counter. This predictability could allow an attacker to potentially infer or manipulate message flows, leading to a low impact on the confidentiality and...

GHSA-VH45-F885-3848 sm-crypto: Predictable SM2 key generation in Node.js: default RNG uses Math.random + wall clock

Summary sm-crypto npm package 0.4.0, the latest release, published 2026-01-20 generates SM2 private keys and signing ephemeral scalars from a single module-wide RNG instance src/sm2/utils.js: const rng = new SecureRandom. SecureRandom is jsbn's PRNG, which seeds an ARC4 stream from...

CVE-2026-6924

A bug in the entropy initialization for SiWx917 causes the DRBG to use a predictable seed. As such, all random numbers generated in the Matter code use the same stream of numbers. This vulnerability was discovered after the impacted repository was already deprecated...

CVE-2026-6924

CVE-2026-6924 describes a weak entropy initialization in SiWx917 TinyCrypt used by Silicon Labs Matter, causing the DRBG to seed from a predictable source. As a result, all random numbers in the Matter code may derive from the same stream, reducing unpredictability. The CVSS vector in the documen...

In Progress® Telerik® UI for AJAX prior to v2026.2.708, when Telerik.Upload.ConfigurationHashKey is absent and machineKey is not explicitly configured, upload metadata integrity protection may fall back to a predictable default key, enabling attackers to forge protected upload metadata and unlock...

SUSE CVE-2026-9323

The urwid web display backend urwid/display/web.py generates web session identifiers urwidid in Screen.start by concatenating two random.randrange109 calls that use Python's Mersenne Twister PRNG, which is not cryptographically secure. Each call consumes approximately 30 bits of PRNG state, and t...

Mistune toc / TableOfContents directive: heading IDs use predictable `toc_N` numbering with no slugification, allowing collision with attacker-controlled `id="toc_N"` content

Summary Type: Predictable identifier generation. The toc plugin and TableOfContents directive both default to generating heading IDs of the form toc1, toc2, toc3, ... with no input-derived component. An attacker who can place a heading anywhere in the document can predict which tocN ID it will...
