Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Pi.Alert is a WIFI / LAN intruder detector with web service monitoring. From 2024-06-29 to before 2026-05-07, the web application endpoint is vulnerable to SQL injection. The /pialert/php/server/devices.php route accepts requests from unauthenticated users when the action URL parameter is set to getDevicesTotals. The scansource URL parameter is then injected in a SQL query. This vulnerability is fixed in 2026-05-07.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

SQL injection vulnerability in Pi.Alert's /pialert/php/server/devices.php endpoint. The scansource URL parameter is not properly sanitized when the action parameter is set to getDevicesTotals, allowing unauthenticated attackers to inject malicious SQL commands.

MitigationUpdate to the patched version released on or after 2026-05-07. If immediate patching is not possible, implement input validation and parameterized queries on the scansource parameter.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Locate Pi.Alert installation directory
    Search for the pialert directory on the system, typically found in /var/www/html/, /home/pi/pialert/, or the web server root.
    Affected if The pialert directory exists and contains the php/server/ subdirectory
  2. Identify installed Pi.Alert version
    Check for a version file, CHANGELOG, or git tags within the Pi.Alert directory. Common locations: /pialert/VERSION, /pialert/CHANGELOG.md, or review git tag output if using git.
    Affected if The version is earlier than the 2026-05-07 patch release
  3. Verify vulnerable file exists
    Confirm the existence of /pialert/php/server/devices.php within the installation directory.
    Affected if The file exists and contains the getDevicesTotals action handler
  4. Confirm application is network accessible
    Determine if the web server hosting Pi.Alert is accessible from network or if the /pialert/php/server/devices.php endpoint is exposed to untrusted networks.
    Affected if The vulnerable endpoint is reachable without authentication from an untrusted network

A user is affected if Pi.Alert is installed with a version prior to the 2026-05-07 patch and the devices.php endpoint is network-accessible without authentication.
