CVE-2025-53549
Matrix Rust SDK allows SQL injection in the EventCache implementation
The Matrix Rust SDK is a collection of libraries that make it easier to build Matrix clients in Rust. An SQL injection vulnerability in the EventCache::find_event_with_relations method of matrix-sdk 0.11 and 0.12 allows malicious room members to execute arbitrary SQL commands in Matrix clients that directly pass relation types provided by those room members into this method, when used with the default sqlite-based store backend. Exploitation is unlikely, as no known clients currently use the API in this manner. This vulnerability is fixed in 0.13.

Matrix Rust SDK vulnerable to SQL Injection through its EventCache implementation
An SQL injection vulnerability in the EventCache::find_event_with_relations method of matrix-sdk 0.11 and 0.12 allows malicious room members to execute arbitrary SQL commands in Matrix clients that directly pass relation types provided by those room members into this method, when used with the default sqlite-based store backend. Exploitation is unlikely, as no known clients currently use the API in this manner.
Workarounds
Passing only trusted (or sanitised) relation types to the filter argument of EventCache::find_event_with_relations() avoids the issue.
Patches
The issue is fixed in matrix-sdk 0.13.

matrix-sdk-sqlite: SQL injection vulnerability in `SqliteEventCacheStore::find_event_with_relations`
The SqliteEventCacheStore::find_event_with_relations function constructs SQL
queries using format!() with unescaped input, allowing an attacker to inject
arbitrary SQL. This results in a SQL injection vulnerability.
