As others have indicated, a VPN server of your choosing (openvpn/wireguard) can solve your issues. Even if at some point there's an "unauthenticated RCE" exploit for gitea, having it behind a VPN will mitigate that.
If you enjoy pentesting, I'd just look for another job, especially since the demand for ex-devs in pentesting is huge. Have a look at a previous comment I posted: https://news.ycombinator.com/item?id=32303528#32305561
I made that exact jump from development to pentesting 6 years ago, after about 10 years of development. Will you miss development? Absolutely. Are there opportunities to scratch that itch? Yes there are - but it's with scripting. The things that can be scripted to make you more efficient are insane. Your ability to understand not only what is broken but also why it's broken will help you advance yourself. You have probably even coded that exact bug in the past so you know where else to look, and you know how to do code reviews. In general, the need for pentesters with a dev background is very very high, especially since now companies worry about supply chain attacks, SDLC, etc.
My solution was to keep coding in my spare time, when I have an MVP I show it at work and then ask for time to work on it. I've significantly improved internall processes, and I've released a few offensive security tools, two of them I even presented at security conferences - as in full blown applications rather than "here's a script that does X". This way I get to pentest and provide solutions to industry-related problems. One thing to note is that most of the security tooling out there (the open sourced ones) is very python/C#/Go centric. I've seen applications written in Rails/Java that didn't get the love they deserved just because it's a pain to install them. I had to learn both python and C#, but it was totally worth it.
If you do make the jump, get ready to take a salary hit as you'd be hired as a mid-level consultant at best - and that's only if you've proven that you know a lot about cyber security, OWASP vulnerabilities, etc. But don't let that stop you, I've seen people join the industry as juniors and in 6 years making over 6 digits (UK). YMMV, but if you put in the time and effort, it's worth it.
The problem is that, in some places (like India, for example) $10 might be a lot of money.
One might be able to do a lot more with $10 in India (₹800), than with $10 in USA, due to reasons that are beyond anybody's control.
For instance, I can travel 3000 km by train with $10 equivalent in India if I really wanted to (wouldn't be very comfortable, but it's possible).
The wages in those countries are also proportional of this.
This becomes relevant if you want your product to be not expensive, so that it reaches a wider audience.
For expensive goods the price difference doesn't matter as much. (Though I know people who were bummed that the Ford Mustang 5.0 V8 was twice as expensive in India than USA — but that's a different market).
I don't have a solution for this, I just think the effort/reward should be considered.
If you want you could pull real-time exchange rates and have a button that indicates the conversion for someone who wants to see the "most likely" price (depending on when they actually pay for it).
For example if you sell something for $9.99 just leave it as such, and Stripe will make the conversion and you'll always sell at the same price regardless from where someone is coming from.
That's how I feel about it anyway!
What got me interested is that Bitwarden is open-source and empowers you to self-host, which for me goes a long way for establishing trust. It has a modern interface through desktop, browser extensions and CLI. You can choose to cloud-host your vault on bitwarden servers, for convenience, with a very generous free tier. Which is what i've been doing for years now, no complaints really.
