Greenlight vs Kurento: at a glance
What is Greenlight?
Greenlight 3.9.1 fixes a critical upload flaw and tells admins to rotate secrets.
Greenlight, the BigBlueButton web frontend, released 3.9.1 on Nov 5 to fix a critical flaw: through a Rails Active Storage issue, a user able to upload an avatar or presentation could read or write files on the server. The fix comes from Rails 8.0.5.2's stricter ImageMagick policy, and instances storing uploads on local disk are told to rotate SECRET_KEY_BASE, database, BigBlueButton and other credentials.
What is Kurento?
Kurento's JavaScript client gets a 7.3.1 point release with no notes.
Kurento is an open-source WebRTC media server, and the only entry in this feed is kurento-client-js 7.3.1, tagged on November 13. The release notes are a single line naming the package and version.

Greenlight, the BigBlueButton web frontend, released 3.9.1 on Nov 5 to fix a critical flaw: through a Rails Active Storage issue, a user able to upload an avatar or presentation could read or write files on the server. The fix comes from Rails 8.0.5.2's stricter ImageMagick policy, and instances storing uploads on local disk are told to rotate SECRET_KEY_BASE, database, BigBlueButton and other credentials.
◆ Where it's heading
The project remains in security maintenance: gem updates, a breaking URL_HOST requirement in 3.9.0 and now an urgent patch. Feature work has been rare since the invitation changes in April.
◆ Prediction
Expect more dependency-driven security releases; new features look unlikely from the recent pattern.

◆ Prediction
It is unclear from one release what comes next; more tags are needed before a direction is visible.
