Description

Sulu is an open-source PHP content management system based on the Symfony framework. Prior to 2.6.25 and 3.0.8, the affected Sulu 2.6 and 3.0 release lines have a Smart Content QueryBuilder in src/Sulu/Component/Content/SmartContent/QueryBuilder.php that concatenates category identifiers from the public categories query parameter into a JCR-SQL2 WHERE clause without numeric validation. On a public page containing a category-filtered Smart Content block, an unauthenticated attacker can alter query conditions to infer or enumerate content-repository nodes, including unpublished content, or submit malformed and expensive query fragments that degrade availability; this path does not modify repository data. This issue is fixed in versions 2.6.25 and 3.0.8.

Exploitability

CWE
CWE Icon
KEV
KEV Icon
CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

CVE-2026-92692 is a JCR-SQL2 injection vulnerability in Sulu CMS versions 2.x up to 2.6.24 and 3.0.x up to 3.0.7. It occurs when the Smart Content QueryBuilder concatenates category identifiers from the public categories query parameter into a JCR-SQL2 WHERE clause without numeric validation. This allows unauthenticated attackers to inject malicious SQL conditions.

Detection Guidance

To detect this vulnerability, inspect Sulu CMS versions for 2.x up to 2.6.24 or 3.0.x up to 3.0.7. Check for unauthenticated access attempts via the categories parameter in Smart Content blocks. Monitor logs for unusual JCR-SQL2 query patterns or boolean-based SQL injection attempts in public pages.

Impact Analysis

An attacker could exploit this to infer or enumerate content-repository nodes, including unpublished content, via blind boolean-based extraction. They could also submit malformed or expensive queries to degrade system availability through denial-of-service attacks. The vulnerability does not allow data modification.

Mitigation Strategies

Upgrade Sulu CMS to versions 2.6.25 or 3.0.8 or later. Temporarily disable category filtering on public Smart Content elements until upgrading. Manually apply the fix by casting category, tag, and audience IDs to integers in QueryBuilder.php as shown in the patch.
