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\nfor 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.","publishedAt":"2026-09-17T20:23:23.616Z","updatedAt":"2026-09-21T21:16:02.110Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["fulgur-rs fulgur"],"affected":[{"vendor":"fulgur-rs","product":"fulgur","versions":[{"version":"< 0.19.0","status":"affected"}]}],"references":["https://github.com/fulgur-rs/fulgur/security/advisories/GHSA-j5cx-ph8g-95v3","https://github.com/fulgur-rs/fulgur/pull/501","https://rustsec.org/advisories/RUSTSEC-2026-0200.html"],"weaknesses":["CWE-400","CWE-835"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/68xxx/CVE-2026-68523.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-68523","state":"PUBLISHED","datePublished":"2026-09-17T20:23:23.616Z","dateUpdated":"2026-09-21T21:16:02.110Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-30T16:19:08.082Z"},"containers":{"cna":{"title":"Fulgur: Unbounded page slicing from attacker-controlled CSS height causes denial of service","descriptions":[{"lang":"en","value":"`fulgur` converts untrusted HTML/CSS into PDF, commonly on a server that processes input supplied by many tenants.
