CyberRota Analysis

AI-Generated

The vulnerability affects the `fulgur` tool, which converts untrusted HTML/CSS into PDF documents, allowing for potential denial-of-service attacks due to unbounded page slicing when processing excessively tall body-direct child elements. This issue has been addressed in version 0.19.0, which introduces a `MAX_PAGES` limit to prevent infinite loops and sanitizes non-finite layout heights. Organizations utilizing `fulgur` for multi-tenant environments should prioritize upgrading to the latest version or implementing strict validation on CSS inputs to mitigate this risk.

Original NVD Description

`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.
