{"cve":"CVE-2025-12387","nvd":{"published":"2026-01-27T12:15:57.243","modified":"2026-06-17T08:32:17.313","status":"Deferred","description":"A vulnerability in the Pix-Link LV-WR21Q router's language module allows remote attackers to trigger a denial of service (DoS) by sending a specially crafted HTTP POST request containing non-existing language parameter. This renders the server unable to serve correct lang.js file, which causes administrator panel to not work, resulting in DoS until the language settings is reverted to a correct value. The Denial of Service affects only the administrator panel and does not affect other router functionalities.\n\nThe vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version V108_108 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":null,"cwes":["CWE-754"],"references":["https://cert.pl/en/posts/2026/01/CVE-2025-12386","https://github.com/wcyb/security_research","https://www.pix-link.com/lv-wr21q"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2025-12387","score":0.00679,"percentile":0.52382,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
