Greenlight vs Red5: 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 Red5?
Red5 2.2.0 makes JDK 25 the minimum after a run of thinly documented patches.
Red5 is a Java media server built around RTMP. Red5 Server 2.2.0 made JDK 25 the baseline, cleaned removed JVM flags out of the launch scripts and fixed service setup, after 2.0.49 made the AMF0 and AMF3 codecs spec-compliant. Tags such as 2.0.53 continue alongside it with no notes beyond a changelog link.

◆ Current state
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.
Red5
5.0MEETINGS
Red5 2.2.0 makes JDK 25 the minimum after a run of thinly documented patches.
◆ Current state
Red5 is a Java media server built around RTMP. Red5 Server 2.2.0 made JDK 25 the baseline, cleaned removed JVM flags out of the launch scripts and fixed service setup, after 2.0.49 made the AMF0 and AMF3 codecs spec-compliant. Tags such as 2.0.53 continue alongside it with no notes beyond a changelog link.
◆ Where it's heading
After the patch run, Red5 is modernizing its runtime and packaging rather than adding media features. The servlet module is back in the build but not yet shipped, so finishing that packaging is the visible open item.
◆ Prediction
A 2.2.x follow-up that packages the servlet module (restoring RTMPT) and fixes service installs on JDK 25 is likely, since the 2.2.0 notes name both as known issues.
