CVE-2026-68523
Published:September 17, 2026
Updated:October 09, 2026
"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 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.
