Summary
Fulgur: Unbounded page slicing from attacker-controlled CSS height causes denial of service
Details

fulgur converts untrusted HTML/CSS into PDF, commonly on a server that processes input supplied by many tenants. In versions prior to 0.19.0, a body-direct child whose CSS-resolved height greatly exceeds the page height was sliced into one fragment per page with no upper bound. This is fixed in version 0.19.0. A MAX_PAGES cap bounds the slice loop — halting it even for a +inf height — and non-finite layout heights are sanitized so they can no longer drive the loop. As a workaround, validate or constrain untrusted CSS (in particular height / vh on body-level elements) before passing HTML to fulgur.
