An attacker who can supply a template can render a near-limit string repeatedly in a loop, allocating approximately 1GB of memory and causing an out-of-memory condition that crashes the host application.","published":"2026-08-16T14:16:56.523","modified":"2026-08-16T14:16:56.523","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/scriban/scriban/security/advisories/GHSA-m2p3-hwv5-xpqw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/scriban-before-denial-of-service-via-unbounded-template-output"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-16T14:16:56.523"}}
