As a result, attackers can exploit this weakness \nto gain unauthorized access to sensitive data or perform unauthorized \nactions. Given that no authentication is required, this can lead to \nprivilege escalation and potentially compromise the security of the \nentire system.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-306"],"references":["https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-022-08.json","https://www.cisa.gov/news-events/ics-advisories/icsa-26-022-08"],"products":["evmapa:evmapa"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2025-54816","score":0.00469,"percentile":0.40632,"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).
