CVE-2026-111492 in MatchPoint
Summary
by MITRE • 11/05/2026
SQL injection in the push notification handler of the MatchPoint Android app, which processes messages from Firebase Cloud Messaging and constructs queries by concatenating untrusted data. An attacker capable of interacting with the component could manipulate queries and access sensitive information from the local database, including credentials stored in the versions described in the report. The scope of the injection is limited to the device.

The vulnerability identified within the MatchPoint Android application represents a classic instance of SQL injection stemming from improper input validation and unsafe query construction practices. Specifically, this flaw resides in the push notification handler component responsible for processing incoming messages via Firebase Cloud Messaging. When the application receives these notifications, it extracts data payloads intended to update user interfaces or trigger local actions. However, instead of treating this external data as inert text values that should be parameterized within database queries, the developer has implemented a pattern where untrusted input is directly concatenated into SQL command strings. This architectural decision bypasses the protective mechanisms provided by prepared statements and parameterized queries, which are designed to ensure that user-supplied data is interpreted strictly as data rather than executable code logic.
From a technical perspective, this flaw aligns with CWE-89, commonly known as Improper Neutralization of Special Elements used in an SQL Command, often referred to simply as SQL Injection. The core issue lies in the failure to sanitize or escape special characters such as single quotes, semicolons, and comment markers within the notification payload before embedding it into a database operation. Because Android applications typically rely on SQLite for local data storage, this concatenation allows an attacker who can influence the content of push notifications to alter the structure of the executed SQL query. By injecting malicious syntax, the attacker can manipulate the query's logic to perform operations beyond the intended scope, such as extracting arbitrary rows from tables containing sensitive user information or modifying existing records.
The operational impact of this vulnerability is significant due to the nature of the data stored locally on the device. The report indicates that credentials are among the pieces of sensitive information accessible through exploitation of this flaw. In many mobile applications, local databases serve as caches for session tokens, authentication keys, or even plaintext passwords if poor security practices were employed during initial development. An attacker capable of interacting with the push notification component can leverage SQL injection to dump these credentials from the SQLite database file located in the application's private storage directory. This access could lead to account takeover, unauthorized actions performed under the victim's identity, or further lateral movement if those credentials are reused across other services.
The scope of this vulnerability is explicitly limited to the local device environment. Unlike server-side SQL injection which can compromise entire backend systems and vast user databases, this flaw affects only the data stored on the specific Android device running the vulnerable version of MatchPoint. This limitation means that while an attacker cannot directly impact remote infrastructure or other users' accounts through this vector alone, they can still cause substantial harm to individual victims by stealing their local session state or credentials. The attack requires some level of interaction with the component, which in this context typically involves receiving a crafted push notification from Firebase Cloud Messaging. If the application does not properly validate the source or content of these notifications before processing them into database operations, any entity capable of sending such messages could potentially exploit this weakness.
Mitigation strategies must focus on correcting the fundamental coding error that allows SQL injection to occur. The primary remediation is to refactor all database interaction code within the push notification handler and other affected components to use parameterized queries or prepared statements. This approach ensures that user input, including data derived from Firebase Cloud Messaging payloads, is treated strictly as literal values rather than executable SQL syntax. Additionally, developers should implement strict input validation on all external data sources before they are processed by any backend logic or database operations. Employing an Object-Relational Mapping framework can also help abstract direct SQL construction and reduce the risk of manual concatenation errors.
From a defensive posture perspective, this vulnerability maps to MITRE ATT&CK techniques related to Data from Local System Retrieval and potentially Command and Control if used for exfiltrating data via push channels. Security teams should prioritize patching this issue in future releases of the MatchPoint application. Users are advised to update their applications immediately upon availability of a patched version. Until then, minimizing trust in incoming notifications and ensuring that mobile device management policies restrict unnecessary permissions can help mitigate some risks associated with local database exposure. Regular security code reviews focusing on data access layers are essential to prevent similar injection flaws from being introduced into other parts of the application ecosystem.
