CVE-2026-39328: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ChurchCRM CRM
ChurchCRM is an open-source church management system. Prior to 7.1.0, a stored cross-site scripting vulnerability exists in ChurchCRM's person profile editing functionality. Non-administrative users who have the EditSelf permission can inject malicious JavaScript into their Facebook, LinkedIn, and X profile fields. Due to a 50-character field limit, the payload is distributed across all three fields and chains their onfocus event handlers to execute in sequence. When any user, including administrators, views the attacker's profile, their session cookies are exfiltrated to a remote server. This vulnerability is fixed in 7.1.0.
AI Analysis
Technical Summary
ChurchCRM versions before 7.1.0 contain a stored XSS vulnerability (CWE-79) in the person profile editing feature. Users with EditSelf permission can inject JavaScript payloads into social media profile fields limited to 50 characters each by chaining onfocus event handlers across Facebook, LinkedIn, and X fields. When a profile containing this payload is viewed, the script executes in the context of the viewer's browser, enabling exfiltration of session cookies to a remote server. This vulnerability is addressed in ChurchCRM 7.1.0.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of other users' browsers, including administrators, leading to session cookie theft. This can result in account compromise and unauthorized access. The vulnerability affects confidentiality and integrity with limited impact on availability.
Mitigation Recommendations
Upgrade ChurchCRM to version 7.1.0 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are documented. Patch status is not explicitly stated beyond the fix in 7.1.0, so applying this update is the recommended mitigation.
