Security readout for executives and security teams
Plain-English summary
CVE-2026-3105 is a high-severity SQL injection in Mautic’s API for retrieving contact activity timelines. An authenticated user could abuse insufficient validation of a sort-direction parameter to alter database queries. For organizations using Mautic, the business risk is possible exposure of sensitive marketing/contact data and limited data or service impact.
Executive priority
Treat this as a near-term patching priority for any production Mautic system, especially if internet-facing or integrated with customer data workflows. Authentication is required, which reduces urgency versus unauthenticated flaws, but SQL injection with high confidentiality impact warrants prompt remediation.
Technical view
The vulnerability is CWE-89 SQL injection in Mautic’s Contact Activity timeline query construction. The sort-direction parameter was not strictly allowlisted, allowing authenticated API users to inject arbitrary SQL through the API. CVSS is 7.6, network exploitable, low complexity, low privileges, no user interaction, with high confidentiality impact.
Likely exposure
Exposure is limited to Mautic deployments where authenticated users or integrations can access the affected contact activity API. The source states Mautic versions from 2.10.0 are affected, but branch-specific vulnerable ranges are not fully detailed beyond the fixed versions.
Exploitation context
No CISA KEV listing is provided, and the supplied sources do not report active exploitation. Exploitation requires authentication, but API accounts, compromised users, or over-privileged integrations could increase practical risk in internet-facing Mautic deployments.
Researcher notes
The advisory attributes the issue to missing allowlist validation for sort direction in the contact activity timeline API. Public details do not include exploit examples, affected branch granularity, or indicators of compromise. Avoid assuming exploitation until supported by KEV or another cited source.
Mitigation direction
- Update Mautic to 4.4.19, 5.2.10, 6.0.8, 7.0.1, or later.
- Prioritize internet-facing Mautic instances and environments with broad API access.
- Review Mautic user and API account permissions for least privilege.
- Monitor vendor guidance for any additional branch-specific instructions.
- No workaround is listed in the advisory.
Validation and detection
- Inventory all Mautic instances and record exact versions.
- Confirm each instance is on a fixed version or later.
- Identify users and integrations with contact activity API access.
- Review application and database logs for unusual authenticated API errors or query anomalies.
- Verify upgrade completion through standard change and vulnerability management records.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
