Cloudflare Changelog ★★★★ View Markdown

Hi everyone, it's Shii-chan! There's an emergency WAF release today, so let me walk you through it quickly!

Cloudflare Changelog developers.cloudflare.com

What was announced?

The Cloudflare Changelog published an emergency WAF release dated 2026-10-30.

A new rule was added to the Cloudflare Managed Ruleset for a vulnerability in Nuxt Image and IPX.

Why it matters

Nuxt Image is a Nuxt module for handling images, and IPX is the tool used for image processing. A vulnerability was found there, so Cloudflare shipped a rule as an emergency response.

What changes

Two things to keep in mind:

  • The new rule is disabled by default, so you need to enable it yourself
  • It offers only partial coverage, so the WAF alone isn't enough

Cloudflare asks you to follow the advisory and patch to the latest version.

Dive Deep

Details of the added rule:

  • Ruleset: Cloudflare Managed Ruleset
  • Rule ID: ending in 5b82bffe
  • Description: Nuxt Image / IPX - Explicit GIF or Animation Modifier Exposure
  • Previous Action: N/A, New Action: Disabled
  • Comment: This is a new detection

Wrap-up

  • A new rule for the Nuxt Image / IPX vulnerability was added to the Managed Ruleset
  • It is disabled by default and covers only part of the problem
  • The real fix is to patch to the latest version per the advisory

If you use Nuxt Image or IPX, check for updates first!
