CVE-2026-46686 emlog CVE debrief
CVE-2026-46686 is a reflected cross-site scripting vulnerability in Emlog 2.6.13 and earlier. The vulnerability exists in the admin backend user search module's keyword parameter, which is processed with addslashes but not HTML-escaped before being rendered into the value attribute in admin/views/user.php. This allows an attacker to inject malicious JavaScript code, potentially leading to reflected cross-site scripting attacks in an administrator's backend session. The vulnerability has a CVSS score of 8.5 and is considered HIGH severity.

Administrators and users of Emlog should be aware of this vulnerability and take necessary precautions to prevent exploitation.
Defensive priority
High
Recommended defensive actions
- Apply patches or updates as soon as they become available.
- Implement input validation and output encoding to prevent cross-site scripting attacks.
- Monitor for suspicious activity and implement compensating controls to detect and prevent exploitation.
- Review compensating controls for exposed systems while remediation is scheduled and verified.
- Check relevant monitoring, detection, and logs for exposed assets that need extra review.
- Track exceptions, retest remediated assets, and close the item only after evidence is documented.
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
