Regular Expression Denial of Service in Acorn
Affected versions of acorn are vulnerable to Regular Expression Denial of Service.
A regex in the form of /[x-\ud800]/u causes the parser to enter an infinite loop.
The string is not valid UTF16 which usually results in it being sanitized before reaching the parser.
If an application processes untrusted input and passes it directly to acorn,
attackers may leverage the vulnerability leading to Denial of Service.
Moderate severity vulnerability that affects acorn and minimist
minimist before 1.2.2 could be tricked into adding or modifying properties of Object.prototype using a "constructor" or "proto" payload.
Moderate severity vulnerability that affects acorn, minimist, and svjsl
There are high severity security vulnerabilities in two of ESLints dependencies:
- acorn
- minimist
The releases 1.8.3 and lower of svjsl (JSLib-npm) are vulnerable, but only if installed in a developer environment. A patch has been released (v1.8.4) which fixes these vulnerabilities.
