mautic/core fixed: 5.2.10 
Upgrade mautic/core to 5.2.10
mautic/core fixed: 6.0.8 
Upgrade mautic/core to 6.0.8
mautic/core fixed: 7.0.1 
Upgrade mautic/core to 7.0.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for mautic/core

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-3105, inspect your project dependencies for Mautic/core:

inspect dependencies for mautic/core

Analyze the terminal output to locate any version of Mautic/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.2.10), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where 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. In Mautic/core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary This advisory addresses a SQL Injection vulnerability in the API endpoint used for retrieving contact activities. A vulnerability exists in the query construction for the Contact Activity timeline where the parameter responsible for determining the sort direction was not strictly validated against an allowlist, potentially allowing authenticated users to inject arbitrary SQL commands via the API. ### Mitigation Please update to **5.2.10**, **6.0.8**, **7.0.1** or later. ### Workarounds None. ### References If there are any questions or comments about this advisory: Email Mautic at [security@mautic.org](mailto:security@mautic.org)
