Synapse is an open-source Matrix homeserver written and maintained by the
Matrix.org Foundation. When users update their passwords, the new
credentials may be briefly held in the server database. While this doesnโt
grant the server any added capabilitiesโit already learns the usersโ
passwords as part of the authentication processโit does disrupt the
expectation that passwords wonโt be stored in the database. As a result,
these passwords could inadvertently be captured in database backups for a
longer duration. These temporarily stored passwords are automatically
erased after a 48-hour window. This issue has been addressed in version
1.93.0. Users are advised to upgrade. There are no known workarounds for
this issue.
