Teams that run a self-hosted Adobe Connect server on Windows, version 12.12 or earlier, are exposed per Adobe's APSB26-191. Exploitation needs a low-privileged account but no user interaction, and Adobe rates scope as changed. Adobe's bulletin lists Windows only and does not say whether Adobe-hosted Connect needed action, so hosted customers should check Adobe's notice.
