AI-suggested
Users should enforce reasonable maximum password lengths to mitigate the risk of event loop blocking. Since the vulnerability affects fallback implementations triggered by native pbkdf2Sync feature check failures, upgrading to Node.js 0.12 or later, or using browser builds, avoids the fallback and thus the vulnerability. Monitor vendor advisories for any future patches or updates.
Description
CVE-2026-102414 is a medium severity vulnerability in the browserify pbkdf2 library up to version 3.1.6. It involves uncontrolled resource consumption due to re-hashing of passwords longer than the digest's block size on every iteration in the JavaScript fallback implementation. This causes a computational cost proportional to the product of iterations and password length, potentially blocking the event loop. The issue affects Node.js versions before 0.12, Bun versions 1.0.0 through 1.1.34 and 1.2.6 and later, and Deno 2.9.0 and later when the fallback is used. Node.js 0.12 and later and browser builds are not affected. Applications that enforce reasonable maximum password lengths are not significantly impacted.
