NCSC-NL published an advisory summarizing Oracle's latest security update for its Communications portfolio, covering products including Oracle Communications Unified Assurance, Cloud Native Core Security Edge Protection Proxy, MetaSolv Solution Module - ASR, Service Catalog and Design, and Operations Monitor. The update addresses 31 vulnerabilities spanning a wide range of weakness classes: path traversal, symlink following, XSS, code injection, SSRF, open redirect, out-of-bounds write, improper certificate validation, incorrect authorization, and resource exhaustion issues, among others. CVSS scores range from low to critical, with 23 of the 31 flaws exploitable remotely without authentication.
Four vulnerabilities are rated critical (CVSS 9.1 or higher): CVE-2026-44024 (CVSS 9.8), CVE-2026-71290 and CVE-2026-73194 (both 9.1), and CVE-2026-17544 (CVSS v4 8.1, listed among the critical set). These reside in core third-party components bundled with Oracle Communications Unified Assurance — Fluentd, PHP, Apache HttpClient, and DBI — and can be exploited remotely without credentials, with high impact to confidentiality and, depending on the flaw, integrity and availability. Successful exploitation across the broader set of vulnerabilities could allow unauthorized access to sensitive data, data modification, or denial of service against affected systems. Some flaws require user interaction or prior access, while others are fully remote and unauthenticated.
NCSC-NL advises prioritizing deployment of patches for the four critical vulnerabilities. No in-the-wild exploitation is reported in this advisory; it is a standard vendor patch release covered by the national CERT. Defenders operating any of the named Oracle Communications products, which are widely used in telecom operator environments, should inventory affected versions and apply Oracle's official updates, referencing the CVE list for prioritization based on CVSS and remote/unauthenticated exploitability.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
