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.
Pull request #310 resolves this issue. Users are advised to update OpenPLC_V3 to pull request #310 or later from the main GitHub repository https://github.com/thiagoralves/OpenPLC_v3 .
