CVE-2025-2746

Kentico Xperience CMS Authentication Bypass Using an Alternate Path or Channel

Kentico Xperience CMS contains an authentication bypass using an alternate path or channel vulnerability that could allow an attacker to control administrative objects.

Description from CISA’s Known Exploited Vulnerabilities catalog

What to do: Attackers are using this now. Install Kentico’s update today. If there is no update for your version, take the product off the internet or stop using it until there is.

What it means for a small business

If your business uses Xperience CMS, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

Why “exploited” matters. Most published flaws are never used. This one is on the list the U.S. government’s cybersecurity agency keeps of flaws it has evidence attackers are using against real systems; federal agencies have to fix it by November 10, 2025. Treat it as today’s job, not this month’s.

Check your own setup

  • Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
  • Server check: what your web server says about itself, and whether that version has known flaws.
