Summary

Picomatch through 4.0.7 contains a regular expression denial of service vulnerability that allows attackers to block the event loop by supplying single-branch repeated extglob patterns. Attackers can provide globs like +(*) or +(*a), which analyzeRepeatedExtglob in lib/parse.js skips, causing exponential backtracking against short crafted strings and denying service to Node.js applications.

Risk Assessment

An attacker could remotely block the Node.js event loop, causing service unavailability for all users.

Recommendation

Update the picomatch library to a version later than 4.0.7 and avoid processing untrusted glob patterns.
