python-cryptography: python-cryptography: Duplicate self-signed intermediates can cause exponential path-building

A flaw was found in python-cryptography. When processing invalid certificate chains that include duplicate self-signed certificates, the system recursively invokes the same certificate, leading to an exponential increase in processing time. A remote attacker could exploit this by providing a...

CVE-2026-5680

A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending specially crafted WebSocket messages with permessage-deflate negotiated. This could lead to excessive memory consumption due to the PerMessageDeflateFunction.largerBuffer method using exponential doubling,...

path-to-regexp vulnerable to Denial of Service via sequential optional groups

Impact A bad regular expression is generated any time you have multiple sequential optional groups curly brace syntax, such as abc:z. The generated regex grows exponentially with the number of groups, causing denial of service. Patches Fixed in version 8.4.0. Workarounds Limit the number of...

Scriban Affected by Memory Exhaustion (OOM) via Unbounded String Generation (Denial of Service)

TemplateContext.LimitToString defaults to 0 unlimited. While Scriban implements a default LoopLimit of 1000, an attacker can still cause massive memory allocation via exponential string growth. Doubling a string for just 30 iterations generates over 1GB of text, instantly exhausting heap memory a...

SUSE CVE-2026-25547

@isaacs/brace-expansion is a hybrid CJS/ESM TypeScript fork of brace-expansion. Prior to version 5.0.1, @isaacs/brace-expansion is vulnerable to a denial of service DoS issue caused by unbounded brace range expansion. When an attacker provides a pattern containing repeated numeric brace ranges, t...

CVE-2026-25547

Affected software: @isaacs/brace-expansion (hybrid CJS/ESM TypeScript fork of brace-expansion). Issue: DoS from unbounded brace range expansion when a pattern contains repeated numeric brace ranges, causing exponential growth and high CPU/memory usage. Root cause: eager generation of all possible...

@isaacs/brace-expansion has Uncontrolled Resource Consumption

Summary @isaacs/brace-expansion is vulnerable to a Denial of Service DoS issue caused by unbounded brace range expansion. When an attacker provides a pattern containing repeated numeric brace ranges, the library attempts to eagerly generate every possible combination synchronously. Because the...
