Description

A flaw was found in the `jsonpath` component of the OpenWrt Project. The `jp_get_token` function, which processes input expressions, contains a memory leak vulnerability. This occurs when dynamically allocated memory used for extracting string literals, field labels, or regular expressions is not properly released after being copied to a new object. This oversight can lead to a gradual depletion of available memory, potentially resulting in a Denial of Service (DoS) for the affected system.
