Software and Data Integrity Failures

OWASP Top 10 category for code and infrastructure that do not protect against integrity violations, such as untrusted updates and insecure deserialization.

Definition

Examples include auto-updates without signature verification, loading libraries from untrusted CDNs without integrity checks, compromised CI/CD pipelines and deserializing untrusted data. Mitigations include digital signatures, Subresource Integrity, trusted repositories, pipeline access controls and avoiding native deserialization of untrusted input.

Example

An application downloads plugin updates over HTTP without verifying signatures.

Exam tip

Insecure deserialization lives in this category since 2021 (A08).
