CVE-2026-30282
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 · uneditedAn arbitrary file overwrite vulnerability in UXGROUP LLC Cast to TV Screen Mirroring v2.2.77 allows attackers to overwrite critical internal files via the file import process, leading to arbtrary code execution or information exposure.
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 · moderate confidenceA path traversal/file overwrite vulnerability in the file import functionality of Cast to TV Screen Mirroring v2.2.77 allows attackers to overwrite arbitrary internal files by manipulating file paths during the import process, potentially leading to code execution or exposure of sensitive application data.

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.
-
Verify the installed application versionCheck the installed version of UXGROUP LLC Cast to TV Screen Mirroring in your device's application manager or package information. Compare it to the affected version 2.2.77.Affected if The installed version is exactly 2.2.77.
-
Locate the file import featureNavigate through the application's menu system or settings to find any file import, file browser, or media import functionality that allows loading external files into the application.Affected if The file import feature exists and is accessible in the application.
-
Check application storage permissionsReview the application's granted permissions, specifically whether it has read/write access to external storage, internal storage, or sandboxed app directories.Affected if The application has write permissions to storage locations outside its private sandbox.
-
Inspect application data directoryExamine the application's internal data directory structure to determine if it allows writing files to locations that could be overwritten via the import function.Affected if The application stores imported files in locations accessible to other applications or the system.
-
Test path traversal capabilityIf you have access to the application, attempt to use the file import function with a crafted file path containing traversal sequences (such as ../) to see if the application permits writing outside its intended directory.Affected if The application permits writing files to directories outside its designated import folder.
You are affected if you have UXGROUP LLC Cast to TV Screen Mirroring version 2.2.77 installed and the file import feature is accessible with storage write permissions.

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 input validation and path sanitization on all file import operations, using allowlist-based filename validation and preventing path traversal sequences (..) to ensure files can only be written to intended directories.
