How to Fix CVE-2026-35588: SQL injection in glances
By Sai Kiran Pandrala. Last verified: 2026-05-25.
| Severity | 6.3 (Medium) |
|---|---|
| Actively exploited? | No public listing in CISA KEV |
| Affected | nicolargo glances < 4.5.4 |
| Fixed in | glances 4.5.4 |
| Type (CWE) | CWE-89: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') |
What is CVE-2026-35588?
Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.4, the Cassandra export module (glances/exports/glances_cassandra/__init__.py) interpolates keyspace, table, and replication_factor configuration values directly into CQL statements without validation. A user with write access to glances.conf can redirect all monitoring data to an attacker-controlled Cassandra keyspace. Version 4.5.4 contains a fix.
Am I affected?
Run the version check that matches your platform:
# Linux
dpkg -s glances 2>/dev/null | grep -i version
rpm -q glances 2>/dev/null
glances --version 2>/dev/null
Compare what you see against the Affected row above (nicolargo glances < 4.5.4). If your build sits inside that range, you are exposed and should patch.
How to fix CVE-2026-35588
The primary fix is to upgrade glances to the patched build. Use the commands for your platform below; the patched version listed in the vendor advisory is: glances 4.5.4.
Ubuntu / Debian
sudo apt-get update
sudo apt-get install --only-upgrade glances
glances --version 2>/dev/null || dpkg -s glances | grep -i version
RHEL / CentOS / Rocky / AlmaLinux
sudo dnf upgrade --security glances -y
rpm -q glances
SUSE / openSUSE
sudo zypper patch --category security
rpm -q glances

If you can't patch immediately
If you cannot apply the patched version today, restrict exposure with one of the following runnable controls. None replace the patch.
Network restriction (Linux, nftables)
# Block inbound traffic to the affected service from untrusted networks
sudo nft add table inet filter
sudo nft 'add chain inet filter input { type filter hook input priority 0 ; }'
sudo nft 'add rule inet filter input tcp dport {443, 80} ip saddr != 10.0.0.0/8 drop'
sudo nft list ruleset
Service-level fallback
# If the affected feature is optional, stop the service until the patch is applied
sudo systemctl stop glances
sudo systemctl disable glances
How to verify the fix worked
# Linux
glances --version 2>/dev/null || dpkg -s glances | grep -i version
rpm -q glances 2>/dev/null || true
# Windows
winget list | findstr /I "glances"
Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 5
Expected: the reported version is at or above glances 4.5.4. Restart any services that loaded the old library (systemctl restart <service> on Linux, restart the Windows service or reboot when prompted). For network appliances, run show version on the device and confirm the build matches the patched release.

Is CVE-2026-35588 actually being exploited?
According to the data sources above, no public confirmation of in-the-wild exploitation at this time. Either way, the fix is the same: apply the vendor patch.
Do I need to reboot after patching?
For OS or kernel updates, yes. For most userland packages a systemctl restart <service> is enough. Any process that loaded the old shared library keeps using it until restarted, so when in doubt, reboot.
What is the CVSS score?
6.3 (medium). Refer to the vendor advisory for the exact vector string.
