The current package homepage http://webdavcgi.sourceforge.net/ does forward to https://danrohde.github.io/webdavcgi/
On the github page there is a 1.1.2 release
Please bump and update the www-apps/webdavcgi ebuild
I'm sorry, but I'm currently too busy to bump and test a new WebDAV CGI release. You're more than welcome to step in if you like.
According to the upgrade notes  a new IO::Compress::Brotli  ebuild would be required as well.
Current stable does not work with stable perl 5.26 because of unescaped left brace
Issue seems to be fixed in upstream in https://github.com/DanRohde/webdavcgi/commit/04e79b7ecbaf3aae5ab813cd4fc0a009c72b1580
thanks a lot for the report and the proposed regex patch. I've finally found some time to rework on the ebuild and update it to the latest upstream version.
