Summary
CVE-2026-39341 is a high-severity SQL Injection (CWE-89) vulnerability in Churchcrm Churchcrm. Its CVSS base score is 8.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 19.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-39341 is a time-based SQL injection vulnerability (CWE-89) affecting ChurchCRM, an open-source church management system, in versions prior to 7.1.0. The issue stems from improper input validation in the endpoint Reports/ConfirmReportEmail.php?familyId=, where user input is sanitized but the sanitized version is not used when constructing the SQL query. This flaw has a CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N), indicating high severity due to its potential for remote exploitation with low privileges.
A low-privileged remote attacker can exploit this vulnerability over the network with low complexity and no user interaction required. By injecting malicious payloads into the familyId parameter, the attacker can manipulate SQL queries to extract sensitive data from the database (high confidentiality impact) or modify database contents (high integrity impact), though availability is unaffected.
The ChurchCRM security advisory at https://github.com/ChurchCRM/CRM/security/advisories/GHSA-3h69-vjff-jj5c confirms the vulnerability and states it is fixed in version 7.1.0, recommending users upgrade to this release or later to mitigate the issue through proper input sanitization in the affected endpoint.
