Roundcube Webmail: SVG feImage bypasses image blocking to track email opens

Link: https://nullcathedral.com/posts/2026-02-08-roundcube-svg-feimage-remote-image-bypass/
Discussion: https://news.ycombinator.com/item?id=46937012

Roundcube's HTML sanitizer doesn't treat SVG feImage href as an image source. Attackers can bypass remote image blocking to track email opens.
