udv@v1 · unaudited · wrong for you until you say what you run

$4.99M is the cost of a breach that happened, from IBM Cost of a Data Breach Report 2026, global average. It is not the value of any asset of yours. That average already covers breaches of every severity, so scaling it by exposure understates a partial-impact record. That is an assumption, not a measurement. Your own asset value goes in the decision record.

A rung lights from a row in the index, never from an assessment. "Held sources" is the true scope of the claim: this index reads the CVE record, NVD, CISA KEV, FIRST's EPSS and public proof-of-concept repositories, and it does not observe attacks.

Did this affect your environment?Answering needs an account.

What it is stated by the CNA

XWiki Platform is a generic wiki platform. A vulnerability in versions from 5.0 to 16.7.1 affects users with Message Stream enabled and a wiki configured as closed from selecting "Prevent unregistered users to view pages" in the Administrations Rights. The vulnerability is that any message sent in a subwiki to "everyone" is actually sent to the farm: any visitor of the main wiki will be able to see that message through the Dashboard, even if the subwiki is configured to be private. This issue will not be patched as Message Stream has been deprecated in XWiki 16.8.0RC1 and is not maintained anymore. A workaround for this issue involves keeping Message Stream disabled by default. receipt

It's advised to keep it disabled from Administration > Social > Message Stream.
