description

turbohtml versions before 1.13.1 can consume excessive stack or memory while compiling or validating XSD and RELAX NG patterns. An attacker may crash the process or a validation thread by supplying a specially constructed schema, if the application accepts and processes untrusted schemas.

mitigation

Upgrade turbohtml to version 1.13.1 or later. Until upgraded, do not compile or validate schemas from untrusted sources, and apply input-size and resource limits where schema processing is necessary.

fixed in 1.13.1
