SCA: security update for pbkdf2 (GHSA-477h-4r7f-fvrx)

medium Tenable Cloud Security Plugin ID 473459

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - pbkdf2 through 3.1.6 re-hashes passwords longer than the digest's block size on every iteration in its
 JavaScript fallback (lib/sync.js). A password longer than the block size (64 bytes, or 128 bytes for
 sha384 and sha512) is passed to HMAC as the key on every iteration, and HMAC hashes such keys in full each
 time. Cost is therefore O(iterations × password length), and a long password can block the event loop. The
 fallback is used by pbkdf2Sync and pbkdf2 on Node.js before 0.12, on Bun (1.0.0 through 1.1.34, and 1.2.6
 and later), and on Deno 2.9.0 and later, because their native pbkdf2Sync fails the library's feature
 check. It is also used when lib/sync.js is imported directly. Node.js 0.12 and later, and browser builds
 (which use lib/sync-browser.js), are not affected. Applications that enforce a reasonable maximum password
 length are not meaningfully affected. (CVE-2026-102414)

Solution

Update the pbkdf2 library and its related packages to version 3.1.7 or later.
