Affected packages
• npm express-basic-auth: < 1.1.7 → fixed in 1.1.7
Description
Versions of `express-basic-auth` prior to 1.1.7 are vulnerable to Timing Attacks. The package uses native string comparison instead of a constant time string comparison, which may lead to Timing Attacks. Timing Attacks can be used to increase the efficiency of brute-force attacks by removing the exponential increase in entropy gained from longer secrets.
Recommendation
Upgrade to version 1.1.7 or later.
