Unsanitized user input in deserialization method

• Rule ID: go_lang_deserialization_of_user_input
• Languages: go
• Source: deserialization_of_user_input.yml

Description

Deserializing data from untrusted sources, like user inputs or request parameters, without proper verification is a security risk. Attackers can embed malicious code or payloads within serialized data. When your application deserializes this data without checks, it becomes vulnerable to attacks.

Remediations

• Do not deserialize data from untrusted sources directly. This can lead to security vulnerabilities.
• Do validate and sanitize all data before deserializing it. Ensure that the data is coming from a trusted source and is in the expected format.
