{"id":"CVE-2026-68537","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.","aliases":["GHSA-4rf6-qx84-q9fv","RUSTSEC-2026-0201"],"modified":"2026-09-19T03:47:22.666206913Z","published":"2026-09-17T20:18:59.957Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68537.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-400","CWE-835"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68537.json"},{"type":"ADVISORY","url":"https://github.com/fulgur-rs/fulgur/security/advisories/GHSA-4rf6-qx84-q9fv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68537"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2026-0200.html"},{"type":"FIX","url":"https://github.com/fulgur-rs/fulgur/pull/501"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/fulgur-rs/fulgur","events":[{"introduced":"0"},{"fixed":"3ed52c28e53de6f6121237e1c9c3e4dd151d574a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.19.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.18.0","v0.17.0","v0.16.0","v0.15.0","v0.14.0","v0.13.0","v0.12.0","v0.11.0","v0.10.0","v0.9.0","v0.8.0","v0.7.0","v0.6.0","v0.5.14","v0.5.13","v0.5.12","v0.5.11","v0.5.10","v0.5.9","v0.5.8","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.2","v0.5.1","v0.5.0","v0.4.5","untagged-548e2812dc7f04b1078f","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.1","v0.3.0","v0.2.0","v0.1.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68537.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
