| Severity | 4.9 (Medium) |
|---|---|
| Actively exploited? | No public listing in CISA KEV |

| Fixed in | See vendor advisory |
| Type (CWE) | CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') |
What is CVE-2026-2429?
The Community Events plugin for WordPress is vulnerable to SQL Injection via the 'ce_venue_name' CSV field in the on_save_changes_venues function in all versions up to, and including, 1.5.8. This is due to insufficient escaping on the user-supplied CSV data and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database via a crafted CSV file upload. The CVSS base score is 4.9 (Medium). The official advisory is at https://www.wordfence.com/threat-intel/vulnerabilities/id/bd184c80-e785-4e9b-961d-9c3378688f91?source=cve.
Am I affected?
Check the version of Community Events you are running and compare it against the Affected row above (Community Events 0 to <=1.5.8). If your build sits inside the affected range, you must patch.
Run the version check that fits your platform:
# Linux package check
dpkg -s community-events 2>/dev/null | grep -i ^Version
rpm -q community-events 2>/dev/null
command -v community-events >/dev/null && community-events --version 2>/dev/null
# Windows (PowerShell)
Get-Package -Name "*Community Events*" -ErrorAction SilentlyContinue | Select-Object Name, Version
winget list --name "Community Events" 2>$null
How to fix CVE-2026-2429
Upgrade Community Events to a patched build: See vendor advisory. The vendor advisory is the source of truth for the exact fixed version.

sudo apt-get update
sudo apt-get install --only-upgrade community-events
dpkg -s community-events | grep -i ^Version
RHEL / CentOS / Rocky / AlmaLinux
sudo dnf upgrade --refresh community-events -y
# or for older releases:
sudo yum update community-events -y
rpm -q community-events
SUSE / openSUSE
sudo zypper refresh
sudo zypper update community-events
rpm -q community-events

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-2026-2429" -Direction Inbound -Action Block -Protocol TCP -LocalPort 80,443 -RemoteAddress Any -Enabled True
Get-NetFirewallRule -DisplayName "Block-CVE-2026-2429"
Disable the affected service (Linux)
sudo systemctl stop community-events 2>/dev/null || true
sudo systemctl disable community-events 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 community-events 2>/dev/null | grep -i ^Version
rpm -q community-events 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 "*Community Events*" | 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.

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.
