CVE-2026-73331 in CamaleonCMS
Summary
by MITRE • 08/12/2026
CamaleonCMS 2.9.1 contains an authenticated SQL injection vulnerability that allows authenticated attackers with post creation or editing privileges to submit a crafted slug value containing SQL syntax that the database backend evaluates as part of an inadequately parameterized query. Attackers can supply malicious slug payloads using boolean- or union-style blind SQL injection techniques to extract sensitive data from the underlying SQLite database, including administrative credentials and configuration values stored in application tables.

CamaleonCMS version 2.9.1 suffers from a critical authenticated SQL injection vulnerability that represents a significant security weakness in the content management system's input handling mechanisms. This vulnerability exists within the slug parameter processing functionality, where user-supplied values are inadequately sanitized before being incorporated into database queries. The flaw specifically affects authenticated users who possess post creation or editing privileges, making it particularly concerning as it can be exploited by insiders or compromised accounts with limited administrative access. The vulnerability manifests when attackers craft malicious slug values that contain SQL syntax which gets evaluated by the SQLite database backend as part of improperly parameterized queries.
The technical exploitation of this vulnerability leverages blind SQL injection techniques, specifically boolean-based and union-style approaches that allow attackers to extract data from the underlying database through carefully constructed payload delivery. When an attacker submits a crafted slug containing malicious SQL code, the application fails to properly escape or parameterize the input before executing database operations, creating opportunities for data extraction attacks. The vulnerability enables unauthorized access to sensitive information stored within application tables, including administrative credentials and configuration values that are typically protected from casual access. This represents a direct violation of data confidentiality principles and can lead to complete system compromise when combined with other attack vectors.
The operational impact of this vulnerability extends beyond simple data theft as it provides attackers with the means to escalate privileges and gain deeper access to the system. Successful exploitation can result in unauthorized administrative access, data manipulation, and potential persistence mechanisms within the application environment. The vulnerability affects the integrity and availability of the CMS infrastructure, as attackers could potentially delete or modify content while maintaining their access. This security weakness directly contravenes industry standards such as CWE-89 which categorizes SQL injection vulnerabilities as critical flaws requiring immediate remediation. Organizations using CamaleonCMS 2.9.1 face significant risk exposure given that the vulnerability requires minimal privileges to exploit and can yield substantial data breaches.
Mitigation strategies should include immediate implementation of proper input validation and parameterization techniques for all database interactions, specifically addressing the slug handling functionality within the application codebase. Security patches or updates from the software vendor should be applied promptly to address the identified SQL injection flaw, while organizations should implement comprehensive monitoring for suspicious slug values and database access patterns. Access controls should be reviewed to ensure that only authorized personnel have post creation or editing privileges, and privilege separation should be enforced to minimize potential damage from compromised accounts. Additionally, regular security testing including automated scanning and manual penetration testing should be conducted to identify similar vulnerabilities in other application components, aligning with ATT&CK framework techniques related to credential access and data extraction operations that this vulnerability enables.
