PYSEC-2023-180

Vulnerability from pysec - Published: 2023-09-27 15:19 - Updated: 2023-09-29 20:23

Details

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.

GHSA-7565-CQ32-VX2X

Vulnerability from github – Published: 2023-09-26 19:20 – Updated: 2024-09-24 17:49

Summary

matrix-synapse vulnerable to improper validation of receipts allows forged read receipts

Details

Impact

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.
