Postiz is an AI social media scheduling tool. From 1.45.1 to 1.62.3, the Postiz frontend application allows an attacker to inject arbitrary HTTP headers into the middleware pipeline. This flaw enables a server-side request forgery (SSRF) condition, which can be exploited to initiate unauthorized outbound requests from the server hosting the Postiz application. This vulnerability is fixed in 1.62.3.
