Giraffe is vulnerable to Improper Restriction of XML External Entity Reference
58
Medium Risk
This Affects:
GiraffeTL;DR
Affected versions of this package are vulnerable to XML External Entity (XXE) Injection due to insecure XML deserialization in the Deserialize function, which uses XmlSerializer without disabling external entity processing. It allows the parser to resolve external entities when processing untrusted XML input. An attacker can exploit this by crafting a malicious XML payload that includes references to external entities, leading to unauthorized file access, server-side request forgery, or denial of service attacks by exhausting system resources.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.

Giraffe is vulnerable to Improper Restriction of XML External Entity Reference in versions 5.0.0 - 8.1.0.
