Executive Summary

CVE-2026-25240 is a SQL injection vulnerability in the user::maintains() function of the PEAR framework prior to version 1.33.0.

The vulnerability occurs when role filters are provided as an array and directly interpolated into an SQL IN (...) clause without proper parameter binding or sanitization.

This improper handling allows an attacker who can influence the role strings passed to this function to inject arbitrary SQL code, potentially manipulating the database.

Impact Analysis

This vulnerability can lead to unauthorized execution of SQL commands due to insufficient sanitization of user inputs.

An attacker exploiting this flaw could manipulate database queries, potentially accessing, modifying, or deleting sensitive data.

Such unauthorized database access can compromise the integrity and confidentiality of your data and disrupt application functionality.

Mitigation Strategies

The primary mitigation step is to upgrade the PEAR framework to version 1.33.0 or later, where this SQL injection vulnerability has been patched.

If upgrading immediately is not possible, review and modify the code in `include/pear-database-user.php` to ensure that role filters are not directly interpolated into SQL queries. Instead, use prepared statements or proper parameter binding to handle arrays in SQL IN clauses.

Additionally, restrict or sanitize any user input that can influence the role filters passed to the `user::maintains()` function to prevent injection of malicious SQL code.

Monitor your systems for unusual database activity that could indicate exploitation attempts.

Compliance Impact

The CVE-2026-25240 vulnerability is a SQL injection flaw that allows unauthorized SQL command execution due to improper sanitization of user inputs. Such vulnerabilities can potentially lead to unauthorized access, modification, or disclosure of sensitive data.

Because of this, affected systems that handle personal or sensitive information may face compliance risks with standards and regulations like GDPR or HIPAA, which require protection of data confidentiality and integrity.

However, the provided information does not explicitly state the impact on compliance with these standards.
