CVE-2024-21643
Microsoft.IdentityModel.Protocols.SignedHttpRequest remote code execution vulnerability
Impact
### Impact _What kind of vulnerability is it? Who is impacted?_ Anyone leveraging the `SignedHttpRequest`protocol or the `SignedHttpRequestValidator`is vulnerable. Microsoft.IdentityModel trusts the `jku`claim by default for the `SignedHttpRequest`protocol. This raises the possibility to make any remote or local `HTTP GET` request. ### Patches _Has the problem been patched? What versions should users upgrade to?_ The vulnerability has been fixed in Microsoft.IdentityModel.Protocols.SignedHttpRequest. Users **should** update **all** their Microsoft.IdentityModel versions to 7.1.2 (for 7x) or higher, 6.34.0 (for 6x) or higher, if using Microsoft.IdentityModel.Protocols.SignedHttpRequest. ### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_ No, users must upgrade. ### References _Are there any links users can visit to find out more?_ https://aka.ms/IdentityModel/Jan2024/jku
