CVE-2026-55865
Python Liquid is a Python engine for the Liquid template language.
Overview
CVE-2026-55865 is a known-severity vulnerability. It was published on July 9, 2026.
Technical description
Python Liquid is a Python engine for the Liquid template language. Prior to 2.2.1, given a malformed {% case %} tag without an associated {% when %} or {% else %} block and no terminating {% endcase %} tag, Python Liquid hangs in an infinite loop at parse time because liquid.TokenStream.eof did not give the EOF token matching kind and value fields, allowing malicious template authors to craft templates for a denial of service attack. This issue is fixed in version 2.2.1.
