Name of the Vulnerable Software and Affected Versions teddy versions prior to 0.5.9

Description A type confusion issue can be exploited to bypass input sanitization when the model content is an array instead of a string. This is related to the teddy package, which is a readable and easy to learn templating language.

Recommendations For versions prior to 0.5.9, update to version 0.5.9 or later to resolve the issue. As a temporary workaround, consider restricting the model content to strings to minimize the risk of exploitation.
