Am I affected?

Check the version of exiftool you are running and compare it against the Affected row above (exiftool 13.0; exiftool 13.1; exiftool 13.2; exiftool 13.3; exiftool 13.4; exiftool 13.5). If your build sits inside the affected range, you must patch.

Run the version check that fits your platform:


# Linux package check
dpkg -s exiftool 2>/dev/null | grep -i ^Version
rpm -q exiftool 2>/dev/null
command -v exiftool >/dev/null && exiftool --version 2>/dev/null


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

How to fix CVE-2026-3102

dpkg -s exiftool | grep -i ^Version

RHEL / CentOS / Rocky / AlmaLinux


sudo dnf upgrade --refresh exiftool -y
# or for older releases:
sudo yum update exiftool -y
rpm -q exiftool

SUSE / openSUSE


sudo zypper refresh
sudo zypper update exiftool
rpm -q exiftool

Node.js / npm


# Update the affected package in your project
npm install exiftool@latest
npm ls exiftool
npm audit fix

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-2026-3102" -Direction Inbound -Action Block -Protocol TCP -LocalPort 80,443 -RemoteAddress Any -Enabled True
Get-NetFirewallRule -DisplayName "Block-CVE-2026-3102"

Disable the affected service (Linux)


sudo systemctl stop exiftool 2>/dev/null || true
sudo systemctl disable exiftool 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 exiftool 2>/dev/null | grep -i ^Version
rpm -q exiftool 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 "*exiftool*" | Select-Object Name, Version
Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 5

Expected: the reported version is at or above exiftool 13.50. Restart the affected service (systemctl restart <service> on Linux, or restart the Windows service) so it loads the patched binary.

Is CVE-2026-3102 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-2026-3102?

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.
