CVE-2020-18194Network attack vector

Stored XSS via crafted blog-post link

Published May 17, 2021 · Updated Aug 4, 2024

Stored cross-site scripting in emlog 6.0.0 allows remote attackers to execute browser-side code via a crafted blog-post link. The blog-post link field accepts a crafted script and later renders it as active content rather than neutralizing it. Exploitation requires a victim to view the resulting post, after which the script runs in that visitor’s browser context and can read or alter site-accessible data.
