brace-expansion: Quadratic-time expansion of the `{a},b}` rewrite causes CPU denial of service

Summary Expanding a,b-shaped input takes time quadratic in the number of literal characters, blocking the event loop. Bash preserves a quirk where a brace group followed by a comma set still expands a,b. The parser implements this by rewriting the string and restarting the scan. Each pass absorbs...

OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. Prior to 7.260706.0, the JSON ingestion mapper's extractWithRegexp formula function compiled a user-supplied regular expression with the JavaScript RegExp engine in...

Astra Linux – Vulnerability in node-path-to-regexp

“path-to-regexp” converts path strings into regular expressions. In some cases, this function may produce regular expressions that can cause poor performance. Since JavaScript is single-threaded, and regex matching occurs on the main thread, poor performance can block the event loop and lead to a...

CVE-2026-90776 Nodemailer 9.1.0 through 10.0.4 Denial of Service via Quadratic Address Parsing

Nodemailer versions 9.1.0 through 10.0.4 contain a quadratic time complexity vulnerability in the addressparser component when parsing email addresses with RFC 5322 comments. Attackers can craft malicious email headers with comment-separated atoms to consume excessive CPU and block the Node.js...

brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity

A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the expand function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-lo...
