Name of the Vulnerable Software and Affected Versions lua-resty-json versions up to commit id 3ef9492bd3a44d9e51301d6adc3cd1789c8f534a

Description A debug function in the lua-resty-json package contained an out of bounds access bug that could have allowed an attacker to launch a Denial of Service (DoS) if the function was used to parse untrusted input data. The debug function was only used in tests and demos, making it not exploitable in a normal environment.

Recommendations For versions up to commit id 3ef9492bd3a44d9e51301d6adc3cd1789c8f534a, consider disabling the debug function to prevent potential exploitation until a patch is available.
