Hi, I'd like to be added to the WMF-NDA group. The security issues I'm interested in helping solve are related to Vuln-XSS, especially fixing such issues (such as T353316/T340221) in a way that doesn't involve using wgRamHtmlMessages (which complicates things for translators over in Translatewiki). In addition to the first task I mentioned, I have already been involved in fixing such issues in T204470 and T154891/T204470.
Adding a few WMF employees who will probably support my request in CC.
