CVE-2025-53549 — Vulnerability in matrix-sdk — CVE Details

MEDIUM

Matrix Rust SDK vulnerable to SQL Injection through its EventCache implementation

Published July 10, 2025Updated July 11, 2025Source: osv

Summary

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. ### References The issue was introduced in https://github.com/matrix-org/matrix-rust-sdk/pull/4849.
