CVE-2026-81672 in iSquad
Summary
by MITRE • 08/27/2026
SQL injection vulnerability in the ‘/ws/apiprensa/getVideoSubcanal’ endpoint due to improper handling of the id_video parameter. The application does not sanitize input before constructing SQL queries, which results in execution errors when malicious input is provided. The vulnerability exposes internal file paths and complete stack traces through the Slim framework’s error handler, which increases the severity due to the combination of information disclosure and SQL injection.

The identified security flaw resides within the /ws/apiprensa/getVideoSubcanal endpoint of a web application built on the Slim PHP microframework. This vulnerability is classified as an SQL Injection (CWE-89), specifically stemming from improper neutralization of special elements used in an SQL command, commonly known as SQLi. The root cause lies in the application's failure to properly sanitize or parameterize the id_video input parameter before incorporating it into database query construction logic. When a user supplies maliciously crafted input for this parameter, the backend system fails to distinguish between executable code and data, allowing the attacker to inject arbitrary SQL commands that are subsequently executed by the underlying database management system.
The operational impact of this vulnerability is twofold, combining traditional injection risks with significant information disclosure issues typical of misconfigured development frameworks. Because the application does not implement robust input validation or prepared statements, an attacker can manipulate the query structure to extract unauthorized data from the database, potentially leading to full compromise of sensitive records such as user credentials, personal identifiable information, or proprietary business logic associated with video subchannels and media content. The immediate consequence observed during exploitation is the triggering of execution errors within the application layer, which serves as a vector for further attacks rather than just a denial of service condition.
A critical aggravating factor in this scenario is the behavior of the Slim framework's error handler when these injection attempts cause syntax or runtime failures. Instead of returning generic error messages to the client, the framework exposes detailed internal file paths and complete stack traces directly in the HTTP response body. This constitutes a severe Information Disclosure vulnerability (CWE-200), as it reveals the underlying directory structure, library versions, and code architecture to potential attackers. The combination of SQL injection capability with this level of environmental visibility significantly lowers the barrier for exploitation, allowing adversaries to map the application's infrastructure accurately and tailor subsequent attacks against specific components or known vulnerabilities in exposed libraries.
From a tactical perspective, this vulnerability aligns with MITRE ATT&CK techniques related to Input Validation failures (T1190) and potentially Exploitation for Credential Access if database credentials are leaked through error messages or secondary injection payloads. The exposure of stack traces also facilitates reconnaissance activities, enabling attackers to identify specific framework versions that may have known remote code execution vulnerabilities, thereby escalating the threat from data theft to full system compromise.
To mitigate this vulnerability, immediate remediation steps must focus on implementing parameterized queries or prepared statements for all database interactions involving user-supplied input. This ensures that the id_video parameter is treated strictly as data rather than executable SQL code, neutralizing the injection vector regardless of the content provided by the client. Additionally, developers should enforce strict input validation and type checking to reject any values that do not conform to expected formats before they reach the database layer.
Beyond code-level fixes, operational mitigations must address the information disclosure aspect. The Slim framework's error handling configuration needs to be adjusted for production environments to suppress detailed stack traces and internal file paths from being returned in HTTP responses. Error messages should be logged server-side while returning generic, non-descriptive error codes or messages to the client side. Implementing a Web Application Firewall (WAF) can also provide an additional layer of defense by detecting and blocking common SQL injection patterns at the network perimeter before they reach the application logic. Regular security testing, including static code analysis and dynamic penetration testing, should be integrated into the development lifecycle to identify similar flaws in other endpoints that may share the same architectural weaknesses.
