## What is CVE-2026-27502?

CVE-2026-27502 is a medium-severity cross-site scripting vulnerability in sa2blv SVXportal, published on 20 Feb 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

SVXportal version 2.5 and prior contain a reflected cross-site scripting vulnerability in log.php via the search query parameter.
