HPE Aruba Networking Fabric Composer Affected by 52 Vulnerabilities Including Five Critical Flaws
HPE has issued an urgent security advisory for its HPE Aruba Networking Fabric Composer network management software after identifying 52 vulnerabilities across multiple components.
The advisory, published on September 1, 2026, covers a wide range of affected areas including the operating system, SSH daemon, web management interface, and API endpoints. Five vulnerabilities are classified as Critical, with several enabling remote code execution or authentication bypass without requiring credentials.
Among the most severe issues is CVE-2026-76657, an API authentication bypass that could allow remote attackers to obtain full administrator privileges. CVE-2026-76658 affects the SSH daemon and permits unauthenticated execution of arbitrary commands with privileged access.
Further critical flaws include CVE-2026-19766, which enables host control from an adjacent network via authentication bypass, and CVE-2026-73700, a cross-site scripting vulnerability in the web management interface. CVE-2026-73701 allows remote code execution without authentication under specific conditions.
HPE strongly recommends that all users apply the available updates immediately to mitigate these risks.

Gmail Address Variants Bypass String Comparison and Enable Multiple Registrations
A single user created four separate accounts using valid Gmail address formats that all deliver to the same inbox: Ivan.Petrov@gmail.com, ivanpetrov@gmail.com, ivan.petrov+shop@gmail.com, and IVAN.PETROV@gmail.com. Simple string comparison in the registration code treated these as distinct entries, allowing circumvention of new-user promotions, free-tier limits, and one-application-per-person rules. The root cause lies in three Gmail-specific behaviors: case-insensitive local parts, plus-addressing that ignores everything after the + symbol, and dots that carry no semantic meaning in the local part. Additional risks arise from IDNA homograph domains that visually mimic legitimate addresses but encode to different Punycode strings. Proper mitigation requires storing both the original email for delivery and a domain-aware normalized form for uniqueness checks, combined with explicit IDNA validation on registration.
Dangling DNS Records Expose Companies to Subdomain Takeovers Years After Projects Shut Down
A marketing team requested reactivation of a three-year-old promotional landing page, only to discover that its domain now served an unrelated third-party website. The root cause was a forgotten CNAME record in the company's DNS zone that continued pointing to a project name on external hosting after the original service had been decommissioned. Because many hosting providers use wildcard DNS entries, standard availability checks and simple DNS resolution tests fail to detect that the target project no longer exists. Attackers who re-register the freed project name can then serve content under the company's legitimate subdomain, automatically obtaining valid TLS certificates and inheriting domain-wide cookies. The article details how such dangling records accumulate across infrastructure, marketing, and acquired company zones, and explains the concrete risks including cookie theft, bypass of Content-Security-Policy, and unauthorized domain ownership proofs. It concludes with a practical remediation workflow: export the full zone, assign owners to every record, validate external targets by application response rather than DNS resolution, and embed record removal into decommissioning procedures.
Google Patches Actively Exploited V8 Zero-Day in Chrome (CVE-2026-85046)
Google has released an urgent update for Chrome to address CVE-2026-85046, a high-severity zero-day vulnerability in the V8 JavaScript engine that is being actively exploited in the wild. The flaw is a type confusion issue within the Maglev compiler, specifically tied to optimizations around Array.prototype.sort, which can lead to arbitrary memory read and write primitives inside the JavaScript heap. Attackers can exploit the vulnerability by tricking victims into visiting a specially crafted HTML page, enabling remote code execution within the browser sandbox. The update brings Chrome to version 152.0.7977.82 or higher on Windows, macOS, and Linux, while also addressing a total of 12 vulnerabilities. The issue was reported by researcher Salvatore Gulizia, known as Serotav, who received a $1,000 reward. Other Chromium-based browsers such as Edge, Brave, Opera, and Vivaldi will require corresponding updates from their vendors.
Google Patches Actively Exploited V8 Zero-Day in Chrome (CVE-2026-85046)
Google has released an urgent update for Chrome to address CVE-2026-85046, a high-severity zero-day vulnerability in the V8 JavaScript and WebAssembly engine that is being actively exploited in the wild. The flaw is a type confusion issue tied to the Maglev compiler and optimizations around Array.prototype.sort, which can lead to arbitrary memory read and write primitives inside the JavaScript heap. Successful exploitation allows a remote attacker to execute arbitrary code within the browser sandbox after a victim visits a specially crafted HTML page, a technique commonly seen in malvertising and compromised-site campaigns. The fix is included in Chrome 152.0.7977.82 and later for Windows, macOS, and Linux, and the update also resolves a total of twelve vulnerabilities. The vulnerability was reported on 4 August 2026 by researcher Salvatore Gulizia, known as Serotav, who received a $1,000 reward. Other Chromium-based browsers such as Microsoft Edge, Brave, Opera, and Vivaldi will require corresponding updates from their respective vendors.
