CVE-2026-36759 Details
Description
A Server-Side Request Forgery (SSRF) in the /themes/{name}/upgrade-from-uri endpoint of halo v2.22.14 allows authenticated attackers to scan internal resources via a crafted GET request.
A Server-Side Request Forgery (SSRF) vulnerability has been identified in Halo version 2.22.14. The issue arises in the '/themes/{name}/upgrade-from-uri' endpoint, allowing authenticated attackers to send crafted GET requests that scan internal resources. The vulnerability exploits the application's plugin upgrade feature, which accepts unvalidated URI input and directly executes HTTP requests without proper security checks. This could lead to unauthorized access to internal services not exposed externally.
It is recommended to implement a blacklist mechanism to filter out internal IP addresses from being accessed via the vulnerable endpoint.
