What is CVE-2026-3024?

Stored Cross-Site Scripting (XSS) vulnerability in the Wakyma web application, specifically in the endpoint 'vets.wakyma.com/configuracion/agenda/modelo-formulario-evento'. A user with permission to create personalized accounts could exploit this vulnerability simply by creating a malicious survey that would harm the entire veterinary team. At the same time, a user with low privileges could exploit this vulnerability to access unauthorized data and perform actions with elevated privileges.

In practical terms, a successful attacker gets execution of attacker-controlled JavaScript in a victim's browser. There is no confirmed in-the-wild exploitation listed in CISA's KEV catalog at the time of writing, but the CVSS rating still warrants prompt patching.

Am I affected?

You're affected if you run Wakyma application web at any version in the Affected row above. Use these probes to find your installed build:


# Confirm the installed version via your package manager
dpkg -l | grep -i wakyma   # Debian/Ubuntu
rpm -qa | grep -i wakyma   # RHEL/CentOS/Rocky

How to fix CVE-2026-3024

The primary fix is to upgrade to the patched build listed in the Fixed in row above (See vendor advisory). Pick the platform that matches your install and run the commands below.

Linux (Ubuntu / Debian)


# Vendor advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-wakyma-application-web
sudo apt-get update
sudo apt-get install --only-upgrade wakyma-application-web
# Confirm the installed version meets or exceeds <patched-version>
dpkg -s wakyma-application-web | grep ^Version

Linux (RHEL / CentOS / Rocky)


sudo dnf upgrade --security wakyma-application-web -y
rpm -q wakyma-application-web

Windows (PowerShell, admin)


# Vendor advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-wakyma-application-web
# Try winget first
winget upgrade --id 'Wakyma.Wakyma application web' --silent --accept-source-agreements --accept-package-agreements
# If winget does not know the product, download the patched installer from the vendor and:
Start-Process -FilePath "$env:TEMP\Wakymaapplicationweb-<patched-version>.msi" -ArgumentList '/qn /norestart' -Wait

# 4. Verify
$verify = (Get-WmiObject -Class Win32_Product |

If you can't patch immediately

These are runnable hardening commands. They reduce blast radius but they're not a replacement for the vendor patch.

Tighten the Content-Security-Policy and cookie flags


add_header Content-Security-Policy "default-src 'self'; script-src 'self'" always;
add_header X-Frame-Options DENY always;
add_header X-Content-Type-Options nosniff always;

How to verify the fix worked

Run the version probe again and confirm the running build matches the Fixed in row above.


# Confirm the running build matches the patched version listed by the vendor
# Example for Linux package installs:
dpkg -l | grep -i "wakyma"   # Debian/Ubuntu
rpm -qa | grep -i "wakyma"   # RHEL/CentOS/Rocky

Expected output: the package version should meet or exceed the patched build.

Then re-run any vulnerability scanner you used previously and confirm the finding for CVE-2026-3024 has cleared. Sweep your logs for the indicators of compromise listed in the vendor or CISA advisory, especially if the system was internet-reachable during the disclosure window.

Frequently asked questions

Is CVE-2026-3024 being actively exploited?

Not at the time of writing. It is not listed in CISA's Known Exploited Vulnerabilities catalog. That status can change, so monitor the vendor advisory and the KEV catalog if the system is exposed.

How severe is CVE-2026-3024?

CVSS rates it 4.8 (Medium). Use that score to set your patch priority next to the other items in your queue.

Do I have to take Wakyma application web offline to apply the patch?

It depends on the deployment. High-availability or clustered installs can usually patch one node at a time with no full outage. Standalone installs typically need a short restart. Always follow the vendor's documented upgrade steps.

What if my vulnerability scanner still flags CVE-2026-3024 after I patch?

Re-run the scan after a service restart, then confirm the scanner's plugin set is up to date. Some scanners detect by banner version only and lag the official fix metadata by a release.
