CVE-2026-111497 Buffer overflow vulnerability in Brotli
Maybe should update your .net and restart opensim/robust
OpenSimulator source has AutomaticDecompression = DecompressionMethods.None set, so probably not vulnerable. However the developers decided to include compiled binaries with the source and these 6 have references to Brotli. *probably not vulnerable* but better safe than sorry I think. :)
OpenMetaverse.dll, RestSharp.dll, Mono.Addins.Setup.dll, BouncyCastle.Cryptography.dll, MimeKit.dll, MailKit.dll
