What are security vulnerabilities in deserialization?

Security vulnerabilities in deserialization occur when untrusted data is converted into an object, potentially allowing attackers to execute malicious code.

Can you give me an example of how this vulnerability can be exploited?

Sure! An attacker might send a crafted serialized object that, when deserialized, triggers unintended behavior, like executing arbitrary code.

How can developers protect against these vulnerabilities?

Developers can protect against deserialization vulnerabilities by validating and sanitizing input, using safe libraries, and implementing strict type checks.

Are there any specific programming languages that are more vulnerable?

Yes, languages like Java and PHP have been known to have more deserialization vulnerabilities due to their object serialization features.
