Microsoft AntiSSRF Library for Python
The Microsoft AntiSSRF Library for Python is a security-developed, exhaustively-tested library that provides robust URL validation to protect Python applications from Server-Side Request Forgery (SSRF) vulnerabilities. It integrates seamlessly with Python requests library, allowing developers to secure outbound HTTP requests with minimal code changes.
How to Use
The AntiSSRF Library provides validation for different scenarios based on your trust requirements:
| Use Case | Description | Documentation Link |

| Azure Key Vault Domain | The untrusted URL must be an Azure Key Vault endpoint. | URIValidator.in_azure_keyvault_domain |
| Azure Storage Domain | The untrusted URL must be an Azure Storage endpoint. | URIValidator.in_azure_storage_domain |
| Allowlist of Trusted Domains | The untrusted URL must belong to a specific, trusted domain. | URIValidator.in_domain |
