Executive Summary

CVE-2026-25239 is a critical SQL injection vulnerability in the pearweb project, specifically in the apidoc_queue insertion process. The vulnerability occurs because the SQL INSERT statement is constructed by directly concatenating a filename variable into the query without proper sanitization or escaping. This allows an attacker who can control the filename value to manipulate the SQL query, potentially executing arbitrary SQL commands.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary SQL commands on the database. This can lead to compromising the integrity and security of the database, including unauthorized data access, data modification, or deletion.

Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by inspecting the source code for unsafe SQL query constructions involving the apidoc_queue insertion, specifically looking for concatenation of unsanitized filename variables into SQL statements.'}, {'type': 'paragraph', 'content': 'On a system where the vulnerable PEAR version is installed, you can check the version of pearweb to confirm if it is prior to 1.33.0, which is vulnerable.'}, {'type': 'paragraph', 'content': 'Since the vulnerability involves SQL injection via the filename variable, monitoring database logs for suspicious or malformed SQL queries involving the apidoc_queue table may help detect exploitation attempts.'}, {'type': 'list_item', 'content': 'Check the installed pearweb version: `pear version` or inspect the pearweb package version in your environment.'}, {'type': 'list_item', 'content': 'Search the source code for unsafe SQL query concatenation patterns, e.g., `grep -r "VALUES (\'" . $file . "\'" ." include/`.'}, {'type': 'list_item', 'content': 'Review database logs for unusual queries on the apidoc_queue table that include unexpected or malicious filename values.'}] [1]

Mitigation Strategies

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

If upgrading immediately is not possible, apply input validation and sanitization on the filename variable before it is used in SQL queries to prevent injection.

Additionally, review and modify the code to use parameterized queries or prepared statements instead of directly concatenating variables into SQL commands.

Monitor your systems and database logs for any signs of exploitation attempts and restrict access to the vulnerable functionality where possible.
