Published: 05 April 2026
Summary
CVE-2026-5574 is a medium-severity Missing Authorization (CWE-862) vulnerability in Technostrobe Hi-Led-Wr120-G2 Firmware. Its CVSS base score is 5.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 41.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement).
Deeper analysis
CVE-2026-5574 is a missing authorization vulnerability affecting the deletefile function within the FsBrowseClean component of Technostrobe HI-LED-WR120-G2 firmware version 5.5.0.1R6.03.30. The issue arises from improper handling of the dir/path argument, allowing bypass of authorization checks. Published on 2026-04-05, it carries a CVSS v3.1 base score of 6.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L) and maps to CWEs-862 (Missing Authorization) and CWE-863 (Incorrect Authorization).
The vulnerability enables remote exploitation by unauthenticated attackers (PR:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation results in limited impacts to integrity (I:L) and availability (A:L), with no confidentiality loss (C:N), potentially allowing unauthorized file deletion on the affected device.
Advisories from VulDB (vuln/355344) and a GitHub repository detail the public disclosure of an exploit, noting it may be actively used. The vendor was contacted early regarding the issue but provided no response, and no patches or official mitigations are referenced in the available sources.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-3 mandates enforcement of approved authorizations for access to system resources like files, directly addressing the missing authorization check in the deletefile function.
AC-14 explicitly prohibits unauthorized actions such as remote file deletion without identification or authentication, countering the PR:N exploitation vector.
SI-2 requires timely identification, reporting, and remediation of flaws like this missing authorization vulnerability in the FsBrowseClean component.
