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.

"details" : "### Summary\nAn SQL injection vulnerability exists in Mautic's API contact filtering mechanism. Due to insufficient recursive sanitization of nested query parameters, an authenticated API user can bypass input filtering and inject arbitrary SQL commands.\n\n### Impact\nAn authenticated user with API access can exploit this vulnerability to execute arbitrary SQL queries against the underlying database. This allows unauthorized retrieval of sensitive database contents—including user credentials, system configurations, and personal identifiable information (PII) of contacts—bypassing standard data access permissions.\n\n### Patched Versions\nThis security issue has been fixed in the following releases:\n* **7.1.2**\n* **6.0.9**\n* **5.2.11**\n* **4.4.20** [ELTS](https://mautic.org/extended-long-term-support-elts/)\n\nWe strongly recommend upgrading to the latest version corresponding to your release branch.\n\n### Workarounds\nThere are no official workarounds. To mitigate this issue without upgrading, you may temporarily disable API access or restrict API permissions to highly trusted accounts.",
