CVE-2026-32843: Linkit ONE Location Aware Sensor System (LASS) Reflected XSS via PM25.php

Location Aware Sensor System by Linkit ONE, up to commit f06bd20 (2023-04-26), contains a reflected cross-site scripting vulnerability in the PM25.php file that allows remote attackers to execute arbitrary JavaScript by injecting malicious code into GET parameters. Attackers can craft a malicious URL containing unencoded payloads in the site, city, district, channel, or apikey parameters to execute scripts in victims' browsers when they visit the page.

Security readout for executives and security teams

Plain-English summary

CVE-2026-32843 is a reflected cross-site scripting issue in Linkit ONE Location Aware Sensor System. A victim must open a crafted link, after which script can run in that browser context. The sources do not show active exploitation or a named patch.

Executive priority

Handle as a moderate web application risk. It is not described as wormable or actively exploited, but public exposure could enable phishing-assisted browser compromise or session misuse. Prioritize verification and vendor guidance over emergency response.

Technical view

The reported flaw is CWE-79 in PM25.php. Unencoded GET parameters named site, city, district, channel, or apikey can be reflected into the page, enabling arbitrary JavaScript execution when a user visits a malicious URL. Affected scope is stated as LASS up to commit f06bd20 from 2023-04-26.

Likely exposure

Exposure is likely limited to organizations running LinkItONEDevGroup LASS with PM25.php reachable by users or the internet. The CVE record lists default affected status as unknown and provides no CPEs, so asset matching may require repository or file-level verification.

Exploitation context

The CVSS vector requires user interaction and no privileges. KEV is false in the source bundle, and no cited source reports active exploitation. Risk rises if trusted users operate authenticated sessions or if affected pages are reachable from public links.

Researcher notes

Evidence is concise but incomplete: the bundle names the vulnerable file, parameters, commit boundary, CWE, and CVSS. It does not provide a fix commit, release version, exploitation evidence, or confirmed product version mapping beyond the repository commit reference.

Mitigation direction

  • Check the LASS repository and VulnCheck advisory for patched releases or maintainer guidance.
  • Limit PM25.php access to trusted networks where operationally possible.
  • Avoid sharing or clicking untrusted PM25.php links until remediation is confirmed.
  • Prioritize output encoding and parameter handling review if maintaining a fork.

Validation and detection

  • Inventory deployments of Linkit ONE LASS and confirm whether PM25.php exists.
  • Check whether code is at or before commit f06bd20 from 2023-04-26.
  • Review PM25.php handling of site, city, district, channel, and apikey parameters.
  • Confirm whether PM25.php is internet-facing or reachable by ordinary users.
