Technical details

The vulnerability is a SQL injection flaw (CWE-89) in src/datastore/postgres/PgDataStore.ts affecting how the roomIds argument is processed when checking room visibility. An attacker who can set malicious Matrix IDs in room mappings can inject SQL commands into database queries. The attack requires administrative control over room configuration; it is not remotely exploitable by unauthenticated users. Successful exploitation could lead to unauthorized data disclosure or modification of the database. The issue was fixed in version 0.36.0 via patch 179313a37f06b298150edba3e2b0e5a73c1415e7.
