The U.S. Cybersecurity and Infrastructure Security Agency (CISA) warned Tuesday that attackers are actively exploiting three vulnerabilities to hack Internet-exposed on-premises SharePoint Server instances. [...]

Threat actors are continuing to exploit a critical Langflow vulnerability as part of fresh attacks designed to deliver a Monero cryptocurrency miner

KDDI Corporation disclosed a breach affecting up to 14.2 million email accounts after attackers exploited a vulnerability in third-party software. KDDI Corporation disclosed a data breach that exposed up to 14.2 million email accounts across six Japanese internet service providers. KDDI Corporation is one of Japan’s largest telecommunications companies. It employs more than 60,000 people […]

Teams digging out of security debt need to answer only two simple questions: Which vulnerabilities in our systems are exposed, and how long should they stay that way?

Breaches don't always start with a zero-day. An exposed admin panel can get brute-forced, or credentials reused from a previous attack. But when a vulnerability does drop — like MongoBleed earlier this year, which let attackers pull credentials and session tokens from server memory without authentication — anything internet-facing is immediately at risk

Attackers are exploiting the critical CVE-2026-10520 flaw in Ivanti Sentry, compromising many internet-exposed gateways shortly after patches were released. Threat actors have started exploiting a maximum-severity OS command injection flaw in Ivanti Sentry, tracked as CVE-2026-10520, that allows remote code execution with root privileges. “An OS Command Injection vulnerability in Ivanti Sentry before the R10.5.2, R10.6.2 and R10.7.1 versions allows a remote […]

Attackers are now targeting a recently patched maximum-severity flaw in Ivanti Sentry, enabling them to execute code with root privileges on Internet-exposed secure mobile gateways. [...]

Attackers are actively exploiting CVE-2026-5027, a high-severity path traversal vulnerability in the AI development platform Langflow, to write arbitrary files on exposed servers. [...]

Over 900 automatic tank gauge (ATG) systems across the United States, used to monitor fuel and chemical storage tanks across various critical infrastructure sectors, have been found exposed online and are vulnerable to ongoing attacks. [...]

Attackers are exploiting vulnerabilities faster than many organizations can identify and patch them. SecAlerts explains why faster vulnerability alerts can help reduce exposure and improve response times. [...]

The Indian Computer Emergency Response Team (CERT-In) has issued new guidelines requiring organizations to patch critical security vulnerabilities in internet-exposed systems within 12 hours of being flagged where "feasible" to safeguard against potential threats stemming from threat actors' abuse of artificial intelligence (AI) tools and large language models (LLMs) to automate vulnerability

A max-severity vulnerability in the latest Python FastAPI version of the ChromaDB project allows unauthenticated attackers to run arbitrary code on exposed servers. [...]

Is the Vulnerability Exposed and Easily Exploitable?Not all supply chain vulnerabilities are alike. Between the exploding volume of new CVEs and the number of actual mass attacks, there lies a sweet spot of just dozens of vulnerabilities to quickly patch to head off risk. No company is able to address every new vulnerability.

Microsoft's total vulnerability count stayed steady in 2025, but critical flaws surged year over year. BeyondTrust breaks down why attackers are increasingly focused on privilege escalation and identity abuse. [...]

Exposed UIs, weak authentication, and risky defaults could turn cloud-native AI apps on Kubernetes into potential targets by threat actors. Learn how exploitable misconfigurations lead to RCE and data leaks. The post When configuration becomes a vulnerability: Exploitable misconfigurations in AI apps appeared first on Microsoft Security Blog.

Every security team has a version of the same story. The quarter ends with hundreds of vulnerabilities closed. The dashboards are bursting with green. Then someone in a leadership meeting asks: "So, are we actually safer now?" Crickets

Over 10,000 Zimbra Collaboration Suite (ZCS) instances exposed online are vulnerable to ongoing attacks exploiting a cross-site scripting (XSS) security flaw. [...]

Over 1,300 Microsoft SharePoint servers exposed online remain unpatched against a spoofing vulnerability that was exploited as a zero-day and is still being abused in ongoing attacks. [...]

Cybersecurity researchers have identified 22 new vulnerabilities in popular models of serial-to-IP converters from Lantronix and Silex that could be exploited to hijack susceptible devices and tamper with data exchanged by them
