CVE-2026-101768

Description

A flaw was found in MySQL Connector/J. An unauthenticated remote attacker with network access via Hypertext Transfer Protocol (HTTP) could exploit this vulnerability to compromise the host application process. A successful attack allows the attacker to take over the application process, potentially leading to unauthorized data modification, sensitive information disclosure, or service disruption.

Statement

This vulnerability is rated as Important due to the severe potential impact, where a remote attacker could achieve complete compromise of the underlying application environment despite high attack complexity. Red Hat Enterprise Linux packages are not affected by this issue, as the supported releases of mysql-connector-java do not contain the vulnerable upstream code.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)

Access Control

Technical Impact: Bypass Protection Mechanism

In some cases, injectable code controls authentication; this may lead to a remote vulnerability.

Access Control

Technical Impact: Gain Privileges or Assume Identity

Injected code can access resources that the attacker is directly prevented from accessing.

Integrity,Confidentiality,Availability

Technical Impact: Execute Unauthorized Code or Commands

When a product allows a user's input to contain code syntax, it might be possible for an attacker to craft the code in such a way that it will alter the intended control flow of the product. As a result, code injection can often result in the execution of arbitrary code. Code injection attacks can also lead to loss of data integrity in nearly all cases, since the control-plane data injected is always incidental to data recall or writing.

Non-Repudiation

Technical Impact: Hide Activities

Often the actions performed by injected control code are unlogged.
