CVE-2025-7156 is a SQL injection vulnerability identified in the hitsz-ids airda product, specifically version 0.0.3. The vulnerability resides in the 'execute' function of the API endpoint /v1/chat/completions. An attacker can manipulate the 'question' argument passed to this endpoint to inject malicious SQL code. This injection flaw allows an unauthenticated remote attacker to execute arbitrary SQL commands on the backend database. The vulnerability does not require user interaction and can be exploited over the network, making it a remotely exploitable flaw. Although the CVSS 4.0 base score is 5.3, classified as medium severity, the vulnerability impacts confidentiality, integrity, and availability to a limited extent due to the partial impact metrics (VC:L, VI:L, VA:L). The attack complexity is low, and no privileges or authentication are required, increasing the risk of exploitation. However, no known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability disclosure is recent (July 2025), and the product version affected is an early release (0.0.3), which may indicate limited deployment but also immature security controls. The SQL injection could allow attackers to extract sensitive data, modify or delete records, or disrupt service depending on the database permissions and schema. The lack of a patch and public exploit availability means organizations using this version of hitsz-ids airda should prioritize mitigation to prevent potential exploitation.

For European organizations, the impact of this vulnerability depends on the adoption of hitsz-ids airda 0.0.3 within their environments. If used in critical systems, especially those handling sensitive or regulated data, the SQL injection could lead to unauthorized data disclosure, data tampering, or denial of service. This could result in breaches of GDPR compliance due to exposure of personal data, leading to regulatory fines and reputational damage. The ability to exploit remotely without authentication increases the risk of widespread attacks, potentially affecting multiple organizations if the product is widely deployed. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement. The medium CVSS score suggests moderate impact, but the real-world consequences could escalate depending on the database privileges and the criticality of the affected systems. European sectors such as finance, healthcare, and government, which often have stringent data protection requirements, would be particularly sensitive to such vulnerabilities.

1. Immediate mitigation should include restricting network access to the /v1/chat/completions endpoint to trusted IP addresses or internal networks only, using firewall rules or API gateways. 2. Implement input validation and sanitization on the 'question' parameter to prevent SQL injection, employing parameterized queries or prepared statements in the codebase. 3. Monitor logs for unusual or suspicious queries targeting the vulnerable endpoint to detect potential exploitation attempts early. 4. If possible, disable or isolate the vulnerable version of hitsz-ids airda until a vendor patch or update is available. 5. Conduct a thorough security review and penetration testing of the affected systems to identify any exploitation or data compromise. 6. Engage with the vendor or community to obtain patches or updates addressing this vulnerability as soon as they are released. 7. Educate development and security teams about secure coding practices to prevent similar injection flaws in future releases.
