    I'm not laughing, because release notes are not funny at all.

    Not even a ETA for full disclosure?

    "Vulnerability fix" is understandable. Full disclosures might be source of issues, but please… At least state some ETA for the disclosure!

    Consider that for some safety/privacy procedures, lacking of the minimal information for assess the risk might lead to a delay for this version adoption!

    I think there is an day 0. Maybe something related to the web page. Close all access from wan it's only way to be secured ( maybe).

    Hi @mMontana & @Omnia,

    This vulnerability is a side effect of the V5.39 patch 0, APC function enhancement; if customers enable HTTPS/SSH on the WAN side, their devices will be exposed to risk and may have the chance to be hacked by using this vulnerability.

    Since this vulnerability was discovered by internal observation, no CVE ID will be applied, and no advisory will be published.
