CVE-2026-55865

CVE-2026-55865 concerns the Python Liquid template engine. Before version 2.2.1, a malformed {% case %} tag without a corresponding {% when %} or {% else %} and without a terminating {% endcase %} could cause an infinite loop during parsing, due to an incorrect EOF token handling in liquid.TokenS...

Infinite loop

Overview python-liquid is an A Python engine for the Liquid template language. Affected versions of this package are vulnerable to Infinite loop in the % case % tag parsing logic, caused by an incorrect definition of the EOF token's kind and value in the TokenStream.eof attribute. A user who can...
