CVE-2025-1835
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 · uneditedA vulnerability has been found in osuuu LightPicture 1.2.2 and classified as critical. This vulnerability affects the function upload of the file /app/controller/Api.php. The manipulation of the argument file leads to unrestricted upload. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.
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 confidenceLightPicture 1.2.2 contains an unrestricted file upload vulnerability in the upload function of /app/controller/Api.php. By manipulating the file argument, a remote attacker can upload arbitrary files to the server, potentially leading to remote code execution.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm LightPicture installationLocate the LightPicture application directory on the server. Common paths include /var/www/html/, /www/wwwroot/, or the webroot directory. Look for the presence of the main application files such as index.php and the /app/ directory structure.Affected if LightPicture is installed on the server
-
Identify installed versionCheck the version file or header within the LightPicture installation. Look for a version.php, composer.json, or similar version declaration file in the application root or /app/ directory.Affected if The installed version is 1.2.2
-
Verify vulnerable file existsInspect the file /app/controller/Api.php to confirm it exists and contains the upload function handling the 'file' argument.Affected if The file /app/controller/Api.php exists and contains an upload handler function
-
Check upload endpoint accessibilityDetermine if the API upload endpoint is accessible by checking web server configuration and routing. The vulnerable path would be the API controller endpoint that handles file uploads.Affected if The upload functionality in Api.php is accessible via the web interface without authentication or proper validation checks
-
Inspect upload directoryCheck the configured upload directory (typically within /uploads/ or /data/ in the webroot) and verify if script execution is enabled or if the directory is outside the webroot.Affected if The upload directory allows execution of uploaded files or is located within the webroot
The environment is affected if LightPicture version 1.2.2 is installed with the vulnerable /app/controller/Api.php upload function accessible and the upload directory permits script execution.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict file type validation using a whitelist approach, verify file content/magic bytes, restrict upload directories outside webroot, and disable script execution in upload directories.
