Token validation methods are susceptible to a timing side-channel during HMAC comparison. With a large enough number of requests over a low latency connection, an attacker may use this to determine the expected HMAC.

A vulnerability, which was classified as critical, has been found in json-pointer up to 0.6.1. Affected by this issue is the function set of the file index.js. The manipulation leads to improperly controlled modification of object prototype attributes ('prototype pollution'). The attack may be launched remotely.

pdftojson commit 94204bb was discovered to contain a stack overflow via the component Stream::makeFilter(char*, Stream*, Object*, int).

pdftojson commit 94204bb was discovered to contain a stack overflow via the component Object::copy(Object*):Object.cc.

A stack overflow in the XML.toJSONObject component of hutool-json v5.8.10 allows attackers to cause a Denial of Service (DoS) via crafted JSON or XML data.

deep-parse-json version 1.0.2 allows an external attacker to edit or add new properties to an object. This is possible because the application does not correctly validate the incoming JSON keys, thus allowing the '__proto__' property to be edited.

fastest-json-copy version 1.0.1 allows an external attacker to edit or add new properties to an object. This is possible because the application does not correctly validate the incoming JSON keys, thus allowing the '__proto__' property to be edited.
