I was the one who reported this originally in 2020. Christian said it wasn't a vulnerability because it was intended that people who used standard library functions should validate user input. A day later I get another email saying that a CVE had been assigned, and that it was now suddenly a vulnerability. I wait a few months, follow up and nothing. Pretty much dropped it for 2 years and now I see that they finally fixed it and never let me know. I asked a few days ago whether I'd be credited in the CVE, still no reply... Why do I feel as if there are serious communication issues here?
