Note that Twisted 22.1.0 has recently been released, which fixes a security issue) within the Twisted library. We do not believe Synapse is affected by this vulnerability, though we advise server administrators who installed Synapse via pip to upgrade Twisted with pip install --upgrade Twisted as a matter of good practice. The Docker image matrixdotorg/synapse and the Debian packages from packages.matrix.org are using the updated library.
