What is CVE-2026-7133?
CVE-2026-7133 is a unrestricted upload flaw in code-projects Online Lot Reservation System. It carries a CVSS base score of 5.1 (medium). It is not currently listed in the CISA Known Exploited Vulnerabilities catalog.
From the source record: A vulnerability was determined in code-projects Online Lot Reservation System 1.0. This impacts an unknown function of the file /activity.php. This manipulation of the argument directory causes unrestricted upload. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized.
Why it matters in practice: The blast radius depends on how the affected service is exposed. An internet-facing instance with no compensating controls is the highest-risk configuration.
Am I affected?
You are affected if your installation of Online Lot Reservation System matches a version listed in the Affected row above.
Check the running version against the Affected row above using the product's admin console or --version flag.
How to fix CVE-2026-7133
Apply the vendor patch. Target the build named in the Fixed in row above (See vendor advisory). The runnable command set below covers the most common deployment patterns for Online Lot Reservation System.
Generic upgrade pattern
If the affected product is a Linux package, upgrade via the system package manager:
# Debian / Ubuntu
sudo apt-get update && sudo apt-get upgrade -y
# RHEL / Rocky / Alma
sudo dnf upgrade --security -y
If it ships as a Windows installer, download the patched build from the vendor advisory and:
# Vendor advisory: https://vuldb.com/vuln/359732
Start-Process msiexec.exe -ArgumentList '/i <patched-installer>.msi /qn /norestart' -Wait
Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | \
Where-Object DisplayName -match '<product-name>' | Select-Object DisplayName, DisplayVersion
After applying the patch
- Restart the service or device so the patched binary loads.
- Confirm the running version matches the Fixed in row using the verification command below.
- Rotate credentials and API keys that the affected service could access if the asset was exposed during the disclosure window.
If you can't patch immediately
Until the patch lands, narrow the attack surface with these runnable controls.
Restrict network exposure
Block public access to the affected service at the perimeter. Allow only trusted source IPs.
# Linux iptables: only allow trusted admin subnet
sudo iptables -A INPUT -p tcp --dport 443 -s 10.10.10.0/24 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 443 -j DROP
sudo iptables-save | sudo tee /etc/iptables/rules.v4
# Windows firewall: only allow trusted admin subnet on management port
New-NetFirewallRule -DisplayName "Restrict-Mgmt-Allow" -Direction Inbound -Action Allow `
-RemoteAddress 10.10.10.0/24 -Protocol TCP -LocalPort 443
New-NetFirewallRule -DisplayName "Restrict-Mgmt-Deny" -Direction Inbound -Action Block `
-Protocol TCP -LocalPort 443
Mitigations are temporary. Apply the vendor patch as soon as a maintenance window opens.
How to verify the fix worked
Confirm the patched build is the one actually running.
Check the running version against the Affected row above using the product's admin console or --version flag.
Expected: a version at or above the patched build named in the vendor advisory.
Also worth doing: pull recent log windows for indicators of compromise listed in the vendor advisory, and re-run an authenticated vulnerability scan with up-to-date signatures.
