- Summary
- Regular Expression Denial of Service (ReDoS) in jsx-slack
- Details
-
jsx-slack v4.5.1 and earlier versions are vulnerable to a regular expression denial-of-service (ReDoS) attack.
Impact
If attacker can put a lot of JSX elements into
<blockquote>tag, an internal regular expression for escaping characters may consume an excessive amount of computing resources./** @jsxImportSource jsx-slack */ import { Section } from 'jsx-slack' console.log( <Section> <blockquote> {[...Array(40)].map((_, i) => ( <p>{i + 1}</p> ))} </blockquote> </Section> )Patches

jsx-slack v4.5.2 has updated regular expressions to prevent catastrophic backtracking.
jsx-slack v4.5.1 also had patched a workaround. It has no problems to contents with ASCII characters, but still vulnerable to contents with multibyte characters. (https://github.com/yhatt/jsx-slack/commit/36e4a10405e4c7745333e245fcc5029c02c7065d)
