Hi, The following vulnerabilities were published for matrix-synapse. CVE-2023-42453[0]: | Synapse is an open-source Matrix homeserver written and maintained | by the Matrix.org Foundation. Users were able to forge read receipts | for any event (if they knew the room ID and event ID). Note that the | users were not able to view the events, but simply mark it as read. | This could be confusing as clients will show the event as read by | the user, even if they are not in the room. This issue has been | patched in version 1.93.0. Users are advised to upgrade. There are | no known workarounds for this issue. CVE-2023-41335[1]: | 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 doesn't grant the server any added capabilities—it already | learns the users' passwords as part of the authentication process—it | does disrupt the expectation that passwords won't 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. If you fix the vulnerabilities please also make sure to include the CVE (Common Vulnerabilities & Exposures) ids in your changelog entry.
