What is CVE-2026-1706?

The All-in-One Video Gallery plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'vi' parameter in all versions up to, and including, 4.7.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The CVSS base score is 6.1 (Medium). The official advisory is at https://www.wordfence.com/threat-intel/vulnerabilities/id/bcaff8ab-2db9-4d91-9b7a-f7f49f5952b9?source=cve.

Am I affected?

Check the version of All-in-One Video Gallery you are running and compare it against the Affected row above (All-in-One Video Gallery 0 to <=4.7.1). If your build sits inside the affected range, you must patch.

Run the version check that fits your platform:


# Linux package check
dpkg -s all-in-one-video-gallery 2>/dev/null | grep -i ^Version
rpm -q all-in-one-video-gallery 2>/dev/null
command -v all-in-one-video-gallery >/dev/null && all-in-one-video-gallery --version 2>/dev/null


# Windows (PowerShell)
Get-Package -Name "*All-in-One Video Gallery*" -ErrorAction SilentlyContinue | Select-Object Name, Version
winget list --name "All-in-One Video Gallery" 2>$null

If you can't patch immediately

Apply at least one of the following inline controls until you can deploy the patched build. None replace the upgrade.

Restrict exposure with nftables (Linux)


# Allow only trusted CIDR to reach the affected service ports
sudo nft add table inet filter 2>/dev/null || true
sudo nft 'add chain inet filter input { type filter hook input priority 0 ; }' 2>/dev/null || true
sudo nft 'add rule inet filter input tcp dport {80, 443} ip saddr != 10.0.0.0/8 drop'
sudo nft list ruleset

Block at the host firewall (Windows)


New-NetFirewallRule -DisplayName "Block-CVE-2026-1706" -Direction Inbound -Action Block -Protocol TCP -LocalPort 80,443 -RemoteAddress Any -Enabled True
Get-NetFirewallRule -DisplayName "Block-CVE-2026-1706"

Disable the affected service (Linux)


sudo systemctl stop all-in-one-video-gallery 2>/dev/null || true
sudo systemctl disable all-in-one-video-gallery 2>/dev/null || true

If the vendor advisory lists an official workaround, prefer that wording verbatim. If no workaround is published, the only safe remediation is the patch.

How to verify the fix worked

After upgrading, confirm the installed version matches the patched build and that no old library is still loaded by a long-running process.


# Linux
dpkg -s all-in-one-video-gallery 2>/dev/null | grep -i ^Version
rpm -q all-in-one-video-gallery 2>/dev/null || true
# Pid map check for old library handles
sudo lsof +c0 2>/dev/null | grep -i "DEL.*lib" || true


# Windows
Get-Package -Name "*All-in-One Video Gallery*" | Select-Object Name, Version
Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 5

Expected: the reported version is at or above See vendor advisory. Restart the affected service (systemctl restart <service> on Linux, or restart the Windows service) so it loads the patched binary.

Frequently asked questions

Other vulnerabilities in the same area that are worth patching alongside this one:

Is CVE-2026-1706 actively exploited?

There is no public confirmation of exploitation in the wild listed in CISA KEV at the time of this writing. Patch anyway. Public exploits commonly follow disclosure within weeks.

Do I need to reboot after patching CVE-2026-1706?

For kernel and OS-level updates, yes. For most userland packages a systemctl restart <service> is enough on Linux, and restarting the Windows service or app on Windows. Any process that loaded the old library keeps using it until restarted.
