For years, security teams and developers alike have struggled with understanding and identifying all security issues affecting their deployed applications. Today, SentinelOne's Wayfinder Frontier AI Services can identify exploitable weaknesses across source code, Software Bill of Materials (SBOM) dependencies, and embedded secrets at unprecedented speed. The problem is that remediation has not accelerated at the same rate.

This post is an unfortunate affirmation of our prior research into abandoned open-source packages, where we found that 11% of the most-downloaded packages have been abandoned and not actively maintained, becoming invisible vulnerabilities to your scanner. Today we share a zip-slip vulnerability we found in extract-zip (CVE-2026-19693), an npm package with over 20 million weekly downloads.

CVE-2026-55040, a critical SharePoint authentication bypass, is now being actively exploited. A proof-of-concept went public on August 11. Within 24 hours, threat intelligence firm Defused confirmed exploitation attempts against its SharePoint honeypots using that same PoC. Over 8,500 SharePoint servers remain reachable from the open internet, putting unpatched instances at immediate risk.

Attackers are using compromised hotel Wi-Fi routers to redirect users to Microsoft 365 phishing sites, according to researchers at ReliaQuest. The attacks were observed in multiple U.S. cities, as well as across India and Saudi Arabia. These types of DNS poisoning attacks can send users to phishing sites with very little evidence that something suspicious has taken place.
