## Affected

- OpenPLC\_V3: fixed in pull request #310

## Description

OpenPLC_V3 is vulnerable to a cross-site request forgery (CSRF) attack due to the absence of proper CSRF validation. This issue allows an unauthenticated attacker to trick a logged-in administrator into visiting a maliciously crafted link, potentially enabling unauthorized modification of PLC settings or the upload of malicious programs which could lead to significant disruption or damage to connected systems.
