MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1565.001 Stored Data Manipulation Impact
Adversaries may insert, delete, or manipulate data at rest in order to influence external outcomes or hide activity, thus threatening the integrity of the data.
Why these techniques?

SQL injection in public-facing pearweb component enables remote exploitation of Internet-facing app (T1190) and directly facilitates stored data manipulation via arbitrary SQL changes to database contents (T1565.001).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

Deeper analysisAI

CVE-2026-25239 is a SQL injection vulnerability (CWE-89) affecting PEAR, a framework and distribution system for reusable PHP components, specifically in the pearweb component. Prior to version 1.33.0, the apidoc queue insertion process fails to properly sanitize the inserted filename value, allowing attackers to manipulate SQL queries. The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N), indicating high severity due to its potential for integrity compromise without requiring authentication or user interaction.

A remote, unauthenticated attacker can exploit this vulnerability over the network with low complexity by supplying a malicious filename value during apidoc queue insertion. Successful exploitation enables arbitrary SQL query manipulation, potentially allowing the attacker to alter database contents, insert unauthorized data, or execute other integrity-impacting operations, though it does not grant confidentiality access or disrupt availability.

The GitHub security advisory (GHSA-f9mg-x463-3vxg) confirms the issue was patched in PEAR version 1.33.0. Security practitioners should upgrade to this version or later to mitigate the vulnerability, and review any custom integrations involving apidoc queue handling for additional input validation.
