CVE-2026-52520: n/a
Emlog CMS versions up to and including 2.6.14 contain a stored cross-site scripting (XSS) vulnerability in the article publishing module. A remote authenticated attacker can inject malicious JavaScript code via article content. When an administrator views or previews the article in the backend, the script executes in the admin's browser session. This can allow the attacker to perform administrative actions such as creating a backdoor administrator account.
AI Analysis
Technical Summary
CVE-2026-52520 describes a stored XSS vulnerability in Emlog CMS <= 2.6.14 within the /admin/article.php module. An attacker with authentication privileges can inject arbitrary JavaScript into article content. The malicious script executes when an administrator reviews or previews the article in the backend, enabling the attacker to escalate privileges by performing administrative actions, including creating unauthorized administrator accounts.
Potential Impact
The vulnerability allows a remote authenticated attacker to execute arbitrary JavaScript in the context of an administrator's session. This can lead to privilege escalation by enabling the attacker to perform administrative actions such as creating backdoor administrator accounts, potentially compromising the entire CMS installation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict article publishing permissions to trusted users only and avoid previewing or reviewing untrusted article content in the admin backend.
