Two things you can do now:

1. Turn off session upload progress

2. Block multipart requests at the web server

Or:

3. Disable PHP entirely on your server, and live with broken sites until the patch arrives.

That's what I did; I can live with my sites being down until it's possible to patch PHP. Though, there are likely others who cannot. The CERT-EU advisory is basically advising the same thing[1].

  • I maintain one old site in PHP. This just got way easier to communicate with my users when I can communicate that major government services are also offline.

    Our current plan is to refactor this into Rust using a coding agent. It looks feasible to get this done today.
