Exploitation status

CISA has not added CVE-2026-28358 to its Known Exploited Vulnerabilities (KEV) catalog, meaning there is no government-confirmed evidence of active exploitation yet. That is no proof of safety, though, since CISA KEV tends to lag actual exploitation, so schedule the fix by severity instead of waiting for confirmation.

Public exploit availability: as of now, no public exploit or Metasploit module appears in the cited references. Unpublished or privately held exploits could still exist, so weak public availability is not a reason to deprioritise.

What is CVE-2026-28358?

NocoDB is software for building databases as spreadsheets. Prior to version 0.301.3, the password forgot endpoint returned different responses for registered and unregistered emails, allowing user enumeration. This issue has been patched in version 0.301.3. The CVSS base score is 2.7 (Low). The official advisory is at https://github.com/nocodb/nocodb/security/advisories/GHSA-387m-j3p9-3php.

Am I affected?

Check the version of nocodb you are running and compare it against the Affected row above (nocodb < 0.301.3). If your build sits inside the affected range, you must patch.

Run the version check that fits your platform:

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

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

How to fix CVE-2026-28358

Upgrade nocodb 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 nocodb
dpkg -s nocodb | grep -i ^Version

RHEL / CentOS / Rocky / AlmaLinux

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

SUSE / openSUSE

sudo zypper refresh
sudo zypper update nocodb
rpm -q nocodb

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-2026-28358" -Direction Inbound -Action Block -Protocol TCP -LocalPort 80,443 -RemoteAddress Any -Enabled True
Get-NetFirewallRule -DisplayName "Block-CVE-2026-28358"

Disable the affected service (Linux)

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

Related weaknesses in the same component worth addressing at the same time:

Is CVE-2026-28358 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-2026-28358?

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.
