    Regular Expression Denial of Service in Acorn

    GHSA-6chw-6frg-f759

    Affected
    • npm acorn >= 6.0.0, < 6.4.1; >= 7.0.0, < 7.1.1; >= 5.5.0, < 5.7.4
    Fixed in
    6.4.17.1.15.7.4· Vendor fix available
    Issue
    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.

    Recommended action: Upgrade to 7.1.1, 6.4.1 or 5.7.4 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
