What is CVE-2026-23982?

An Improper Authorization vulnerability exists in Apache Superset that allows a low-privileged user to bypass data access controls. When creating a dataset, Superset enforces permission checks to prevent users from querying unauthorized data. However, an authenticated attacker with permissions to write datasets and read charts can bypass these checks by overwriting the SQL query of an existing dataset.

This issue affects Apache Superset: before 6.0.0.

Users are recommended to upgrade to version 6.0.0, which fixes the issue. The CVSS base score is 7.1 (High), which puts this in the upper risk band and warrants a fast patch cycle. The official advisory is at https://lists.apache.org/thread/9lvbzwkw4rxgdvbpfvnnnfcll92v75fp.

Am I affected?

Check the version of Apache Superset you are running and compare it against the Affected row above (Apache Superset 0.0.0 to <6.0.0). If your build sits inside the affected range, you must patch.

Run the version check that fits your platform:


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


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

How to fix CVE-2026-23982

Upgrade Apache Superset to a patched build: See vendor advisory. The vendor advisory is the source of truth for the exact fixed version.

Ubuntu / Debian


sudo apt-get update
sudo apt-get install --only-upgrade apache-superset
dpkg -s apache-superset | grep -i ^Version

RHEL / CentOS / Rocky / AlmaLinux


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

SUSE / openSUSE


sudo zypper refresh
sudo zypper update apache-superset
rpm -q apache-superset

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-2026-23982" -Direction Inbound -Action Block -Protocol TCP -LocalPort 80,443 -RemoteAddress Any -Enabled True
Get-NetFirewallRule -DisplayName "Block-CVE-2026-23982"

Disable the affected service (Linux)


sudo systemctl stop apache-superset 2>/dev/null || true
sudo systemctl disable apache-superset 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 apache-superset 2>/dev/null | grep -i ^Version
rpm -q apache-superset 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 "*Apache Superset*" | 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.

Is CVE-2026-23982 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-2026-23982?

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.
