CVE-2026-24572 is classified as a high-severity vulnerability that allows for blind SQL injection in the Nelio Software Nelio Content plugin. This vulnerability allows attackers to manipulate SQL queries executed by the application, potentially leading to unauthorized data access and exposure. The CVSS score of 8.5 indicates high risk, and organizations should prioritize addressing this vulnerability.
The vulnerability affects versions of Nelio Content up to and including 4.2.0. With an attack vector of network and low complexity, the potential for exploitation is significant. Thus, organizations utilizing this plugin must take immediate action to mitigate risks.
Organizations should prioritize patching immediately. Given the simplicity of the attack, the risk to organizations includes exposure of sensitive information and potential data breaches stemming from successful exploitation.
Currently, there are no known exploits or public proof-of-concept available for this vulnerability. However, the potential impact remains significant, warranting urgent attention from security teams.
Vulnerability Details
The CVE description indicates that this SQL Injection vulnerability allows for blind SQL injection, affecting Nelio Content from n/a through version 4.2.0. The CVSS version 3.1 score of 8.5 categorizes this as high severity, with a significant impact on confidentiality and a low impact on availability.
The CWE classification for this vulnerability is CWE-89, specifically associated with improper neutralization of special elements within SQL commands. The vulnerability was published on January 23, 2026.
Technical Analysis
The root cause of CVE-2026-24572 lies in the improper handling of user inputs within SQL commands. Attackers may leverage this vulnerability by crafting specific payloads that could manipulate SQL queries, allowing them to bypass authentication and access sensitive data.
The attack vector is network-based, requiring no physical access to the server, making it particularly dangerous. The attack complexity is low, and the privileges required for exploitation are minimal, which increases the likelihood of successful attacks. User interaction is not required, further enhancing the risk.
In terms of impact, the confidentiality impact is rated high as attackers can potentially access sensitive information. The integrity impact is none, while availability impact is low, indicating that the system's functionality is not directly compromised.
Risk & Impact Analysis
Real-world risk to organizations includes unauthorized access to sensitive information, which can lead to data breaches and compliance violations. The blast radius of this vulnerability can be extensive, especially if the affected plugin is widely used across multiple installations.
Given the high CVSS score and the potential for exploitation, organizations should assess their vulnerability management processes and prioritize remediation efforts accordingly. The urgency is underscored by the lack of known public exploits, which may encourage attackers to develop their own methods of exploitation.
The EPSS score for this vulnerability is 0.00016, indicating a low probability of exploitation in the wild, but organizations should not become complacent. Continuous monitoring and proactive security measures are essential.
