Ask HN: A company wants a photo in the CV. Red flag?

Depends which country you are in. Regrettably, in Germany this is standard practice.

I'd call the photo request a reasonable precaution in the context of hiring fraud.

That would be incompatible with a blind audition but those are rare.

In Mexico is standard practice too.
