Ivanti is warning that a new security flaw impacting Endpoint Manager Mobile (EPMM) has been explored in limited attacks in the wild. The high-severity vulnerability, CVE-2026-6973 (CVSS score: 7.2), is a case of improper input validation affecting EPMM before versions 12.6.1.1, 12.7.0.1, and 12.8.0.1. It allows "a remotely authenticated user with administrative access to achieve remote code execution," Ivanti said in an advisory released today. "We are aware of a very limited number of customers exploited with CVE-2026-6973. Successful exploitation requires Admin authentication. If customers followed Ivanti's recommendation in January to rotate credentials if you were exploited with CVE-2026-1281 and CVE-2026-1340 , then your risk of exploitation from CVE-2026-6973 is significantly reduced." It's currently not known who is behind the exploitation efforts, if any of those attacks were successful, and what the end goals of the attacks were. The devel...

Palo Alto Networks has disclosed that threat actors may have attempted to unsuccessfully exploit a recently disclosed critical security flaw as early as April 9, 2026. The vulnerability in question is CVE-2026-0300 (CVSS score: 9.3/8.7), a buffer overflow vulnerability in the User-ID Authentication Portal service of Palo Alto Networks PAN-OS software that could allow an unauthenticated attacker to execute arbitrary code with root privileges by sending specially crafted packets. While fixes are expected to be released starting May 13, 2026, customers are advised to secure access to the PAN-OS User-ID Authentication Portal by restricting access to trusted zones, or by disabling it entirely if it's not used. As additional mitigation, the company is recommending that organizations disable Response Pages in the Interface Management Profile for any L3 interface where untrusted or internet traffic can ingress. Customers with Advanced Threat Prevention can also block exploitation a...

A dozen critical security vulnerabilities have been disclosed in the vm2 Node.js library that could be exploited by bad actors to break out of the sandbox and execute arbitrary code on susceptible systems. vm2 is an open-source library used to run untrusted JavaScript code inside a secure sandbox by intercepting and proxying JavaScript objects to prevent sandboxed code from accessing the host environment. The security flaws are listed below - CVE-2026-24118 (CVSS score: 9.8) - A vulnerability that allows sandbox escape via "__lookupGetter__" and permits an attacker to run arbitrary code on the underlying host. (Affects versions <= 3.10.4, patches in 3.11.0) CVE-2026-24120 (CVSS score: 9.8) - A patch bypass for CVE-2023-37466 (CVSS score: 9.8) that could allow attackers to escape the sandbox through the species property of promise objects and execute arbitrary commands on the underlying host. (Affects versions <= 3.10.3, patched in 3.10.5) CVE-2026-24781 (CVSS ...

Palo Alto Networks has released an advisory warning that a critical buffer overflow vulnerability in its PAN-OS software has been exploited in the wild. The vulnerability, tracked as CVE-2026-0300 , has been described as a case of unauthenticated remote code execution. It carries a CVSS score of 9.3 if the User-ID Authentication Portal is configured to enable access from the internet or any untrusted network. The severity comes down to 8.7 if access to the portal is restricted to only trusted internal IP addresses. "A buffer overflow vulnerability in the User-ID Authentication Portal (aka Captive Portal) service of Palo Alto Networks PAN-OS software allows an unauthenticated attacker to execute arbitrary code with root privileges on the PA-Series and VM-Series firewalls by sending specially crafted packets," the company said . According to Palo Alto Networks, the vulnerability has come under "limited exploitation," specifically targeting instances where the Use...

The Apache Software Foundation (ASF) has released security updates to address several security vulnerabilities in the HTTP Server, including a severe vulnerability that could potentially lead to remote code execution (RCE). The vulnerability, tracked as CVE-2026-23918 (CVSS score: 8.8), has been described as a case of "double free and possible RCE" in the HTTP/2 protocol handling. This issue affects Apache HTTP Server 2.4.66 and has been addressed in version 2.4.67. Striga.ai co-founder Bartlomiej Dmitruk and ISEC.pl researcher Stanislaw Strzalkowski have been credited with discovering and reporting the vulnerability. When reached for comment, Dmitruk told The Hacker News via email that the severity of CVE-2026-23918 is critical, as it can be exploited to achieve denial-of-service (DoS) and RCE. Additional details of the vulnerability are below - CVE-2026-23918 is a double-free in Apache httpd 2.4.66 mod_http2 , specifically in the stream cleanup path of h2_mplx.c. T...
