A serialization bug in matrix-sdk-base allows remote attackers to cause denial-of-service by sending rooms with custom m.room.join_rules values, which stalls the sync process and prevents all room processing. The vulnerability affects matrix-sdk-base versions 0.14.1 and prior and has a high availability impact (CVSS 7.5) with a patch available in version 0.16.0. With a low EPSS score of 0.06% and no KEV listing, this represents a moderate real-world risk primarily concerning service availability rather than active exploitation.
