What is CVE-2026-85612?

OpenPanel versions prior to 2.3.0 are susceptible to an unauthenticated server-side request forgery (SSRF) vulnerability affecting the /misc/favicon and /misc/og endpoints. This flaw allows attackers to manipulate the url parameter, leading the API to retrieve information from arbitrary internal hosts and cloud metadata endpoints. This capability can facilitate credential theft and provide attackers with the means to enumerate internal services, posing significant security risks.

Affected Version(s)

openpanel 0 < 2.3.0

openpanel 2.3.0

Exploit Proof of Concept (PoC)
