[dependabot-preview]

Bumps acorn from 5.7.1 to 5.7.4. This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

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.

Identifiers:

• CVE-2020-7598
• SNYK-JS-ACORN-559469 (doesn&Add support for validating NANO addresses ognus/wallet-address-validator#39;t have a CVE identifier)

Affected versions: < 5.7.4

Sourced from The GitHub Security Advisory Database.

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.

Affected versions: < 5.7.4

Sourced from The GitHub Security Advisory Database.

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.

Affected versions: >= 5.5.0 < 5.7.4
