CVSS: 6.8EPSS: 3%CPEs: 1EXPL: 0CVE-2024-31208 – Synapse's V2 state resolution weakness allows DoS from remote room members
https://notcve.org/view.php?id=CVE-2024-31208
23 Apr 2024 — Synapse is an open-source Matrix homeserver. A remote Matrix user with malicious intent, sharing a room with Synapse instances before 1.105.1, can dispatch specially crafted events to exploit a weakness in the V2 state resolution algorithm. This can induce high CPU consumption and accumulate excessive data in the database of such instances, resulting in a denial of service. Servers in private federations, or those that do not federate, are not affected. Server administrators should upgrade to 1.105.1 or lat... • https://github.com/element-hq/synapse/commit/55b0aa847a61774b6a3acdc4b177a20dc019f01a • CWE-770: Allocation of Resources Without Limits or Throttling •

The impact of the attack is reduced by the fact that the databases stored in this folder are encrypted. However, it contains some other potentially sensitive information, such as the FCM token. Forks of Element Android which have... • https://element.io/blog/security-release-element-android-1-6-12 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
