Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-30282 is an arbitrary file overwrite vulnerability in UXGROUP LLC's Cast to TV Screen Mirroring version 2.2.77. The issue arises in the file import process, enabling attackers to overwrite critical internal files and potentially achieve arbitrary code execution or information exposure. It maps to CWE-22 (Path Traversal) and CWE-73 (External Control of File Name or Path), with a CVSS v3.1 base score of 9.0 (AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H). The vulnerability was published on 2026-03-31T18:16:47.123.
The attack requires network access, low complexity, low privileges such as an authenticated user account, and user interaction to import a malicious file. A low-privileged attacker can exploit this to overwrite files, escalating impact across confidentiality, integrity, and availability with high severity due to the changed scope, ultimately enabling arbitrary code execution or data exposure on the targeted system.

Mitigating Controls (NIST 800-53 r5) AI
Enforces the intended directory access authorizations that path traversal would otherwise bypass.
Input validation directly neutralizes special path elements before pathname construction occurs.
Least privilege reduces the impact of any unauthorized file access obtained via traversal.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices include input validation and path sanitization that eliminate this weakness.
Least-privilege file authorization directly limits damage from externally controlled paths.
Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
