Software versions inside a published affected range (1, 1 known-exploited)

The public response carried a version for these products, and NVD publishes an affected range that contains it. This is not proof the software is unpatched — a distribution backport keeps the original version string while carrying the fix, so a fully patched build can appear here. Both halves of the comparison are public and checkable.

Ransomware leak-site listings (1)

This domain is named on the public leak site of a ransomware group. A leak-site post is a claim published by the group — not a verified fact, and not a statement by this organization. Groups list victims who did not pay, overstate what they hold, and occasionally name the wrong company. What is certain is that the listing itself is public.
