This link is maintained to preserve external references.\n\n## Original Description\nNokogiri versions before 1.19.3 contain a memory leak in the XSLT Stylesheet transform method when processing Ruby strings containing null bytes. Attackers can exploit this by passing attacker-controlled input with null bytes to transform parameters, causing heap allocations to leak and enabling denial of service against long-running processes.","published":"2026-08-25T18:31:52Z","modified":"2026-09-03T16:25:58.589111857Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"RubyGems","name":"nokogiri","fixedVersion":null}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-v2fc-qm4h-8hqv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-79771"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/nokogiri-before-memory-leak-via-xslt-transform"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-03T16:25:58.589111857Z"}}
