This is also why an `app.` or even better `tenant.` subdomain is always a good idea; it limits the blast radius of mistakes like this.
Cool bug. Bug bounty money is pathetic.
What is the reason for the low values? I would understand if it was a small company, but we are talking about Discord here.
The fact that SVG files can contain scripts was a bit of a mistake. On one hand, the animations and entire interactive demos and even games in a single SVG are cool. But on the other hand, it opens up a serious can of worms of security vulnerabilities. As a result, SVG files are often banned from various image upload tools, they do not unfurl previews, and so on. If you upload an SVG to discord, it just shows the raw…

(Yes I'm still salty about Flash.)
Seems like such a tiny amount of money for a bug that can be used to completely own your customers accounts. Also not much excuse for xss these days.
XSS is not dead, and the web platforms mitigations (setHTML, Trusted Types) are not a panacea. CSP helps but is often configured poorly.
So, this kind of widespread XSS in a vulnerable third party component is indeed concerning.
For another example, there have been two reflected XSS vulns found in Anubis this year, putting any website that deploys it and doesn't patch at risk of JS execution on their origin.
Audit your third-party dependencies!

If only there was a widely used vector format that had script support and also decades of work on maintaining a battle-tested security layer around it with regular updates on a faster release cycle than your browser. That'd be crazy. Sure would suck if we killed it because we didn't want to bother maintaining it anymore. (Yes I'm still salty about Flash.)
I've never heard an XSS vulnerability described as a supply-chain attack before though, usually that one is reserved for package managers malicious scripts or companies putting backdoors in hardware.

Do you allow SVGs to be uploaded anywhere on your site? This is a PSA that you're probably at risk unless you can find the few hundred lines of code doing the sanitization.
Note to Ruby on Rails developers, your active storage uploaded SVGs are not sanitized by default.
