Technical details
The cn_parse_url() function in CuteNews 2.1.2 unsafely deserializes the __post_data parameter, which accepts base64-encoded PHP serialized objects. An unauthenticated remote attacker can send a crafted payload to inject arbitrary internal variables including __referer without authentication, leading to potential privilege escalation or authorization bypass.
