{"cve":"CVE-2026-68523","nvd":{"published":"2026-09-17T21:17:19.127","modified":"2026-09-24T21:25:27.050","status":"Deferred","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\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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400","CWE-835"],"references":["https://github.com/fulgur-rs/fulgur/pull/501","https://github.com/fulgur-rs/fulgur/security/advisories/GHSA-j5cx-ph8g-95v3","https://rustsec.org/advisories/RUSTSEC-2026-0200.html"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-68523","score":0.00609,"percentile":0.49179,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-j5cx-ph8g-95v3","url":"https://osv.dev/vulnerability/GHSA-j5cx-ph8g-95v3","summary":"Fulgur: Unbounded page slicing from attacker-controlled CSS height causes denial of service","modified":"2026-09-17T19:10:56.536332750Z","packages":[{"ecosystem":"crates.io","name":"fulgur","purl":"pkg:cargo/fulgur","ranges":["<0.19.0"],"fixed":["0.19.0"]}]},{"id":"RUSTSEC-2026-0200","url":"https://osv.dev/vulnerability/RUSTSEC-2026-0200","summary":"Unbounded page slicing from attacker-controlled CSS height causes denial of service","modified":"2026-10-12T18:00:14.901266329Z","packages":[{"ecosystem":"crates.io","name":"fulgur","purl":"pkg:cargo/fulgur","ranges":[">=0.0.0-0 <0.19.0"],"fixed":["0.19.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
