Impact This is not a vulnerability in the code per se, but included platform.sh Varnish VCL templates and Apache/Nginx vhost templates enable compression of API and JSON messages. This is a potential case of the BREACH vulnerability, which affects HTTP compression, where secrets can be extracted through carefully crafted requests. The fix disables compression in these templates. Please make sure to make the same change in your configuration files, see the release notes for specific instructions. Patches See "Patched versions". v1.0: https://github.com/ibexa/post-install/commit/d91cc02623dd3263a99a94ace133c95e48909e5d v4.6: https://github.com/ibexa/post-install/commit/ae7c3c2081a862c75b90828f08bd74436ceb8fe8 Workarounds Make sure HTTP compression is disabled for REST API requests and other communication that might contain secrets.
