Highly rated RCE in CUPS - Openwrt affected?

[q9q]

Hello,

A few days ago a RCE was discovered in the CUPS software and it has a highly rated severity. The researcher who was discovering this wrote a nice blog post about it: CUPS RCE

I am running p910nd on my router. Am I affected by this RCE? What would be a way to mitigate?

And, do I need to wait for Openwrt 23.05.6 or can I just update the CUPS packages (if there will be updates available)?

Did you use the forum search before?

It's been -unsurprisingly- asked before, and answered.

p910nd is entirely different than CUPS. They’re not even remotely similar.

Am I affected by this RCE?

Nope.
