Vulnerability | Breaking Cybersecurity News | The Hacker News

This week had real hits. The key software got tampered with. Active bugs showed up in the tools people use every day. Some attacks didn’t even need much effort because the path was already there. One weak spot now spreads wider than before. What starts small can reach a lot of systems fast. New bugs, faster use, less time to react. That’s this week. Read through it. ⚡ Threat of the Week Axios npm Package Compromised by N. Korean Hackers —Threat actors with ties to North Korea seized control of the npm account belonging to the lead maintainer of Axios, a popular npm package with nearly 100 million weekly downloads, to push malicious versions containing a cross-platform malware dubbed WAVESHAPER.V2. The activity has been attributed to a financially motivated threat actor known as UNC1069. The incident demonstrates how quickly the compromise of a popular npm package can have ripple effects through the ecosystem. T...

Fortinet has released out-of-band patches for a critical security flaw impacting FortiClient EMS that it said has been exploited in the wild. The vulnerability, tracked as CVE-2026-35616 (CVSS score: 9.1), has been described as a pre-authentication API access bypass leading to privilege escalation. "An improper access control vulnerability [CWE-284] in FortiClient EMS may allow an unauthenticated attacker to execute unauthorized code or commands via crafted requests," Fortinet said in a Saturday advisory. The issue affects FortiClient EMS versions 7.4.5 through 7.4.6. It's expected to be fully patched in the upcoming version 7.4.7, although the company has released a hotfix to address it.  Simo Kohonen from Defused Cyber and Nguyen Duc Anh have been credited with discovering and reporting the flaw. In a post on X, Defused Cyber said it observed zero-day exploitation of CVE-2026-35616 earlier this week. Accor...

A large-scale credential harvesting operation has been observed exploiting the React2Shell vulnerability as an initial infection vector to steal database credentials, SSH private keys, Amazon Web Services (AWS) secrets, shell command history, Stripe API keys, and GitHub tokens at scale. Cisco Talos has attributed the operation to a threat cluster it tracks as UAT-10608 . At least 766 hosts spanning multiple geographic regions and cloud providers have been compromised as part of the activity. "Post-compromise, UAT-10608 leverages automated scripts for extracting and exfiltrating credentials from a variety of applications, that are then posted to its command-and-control (C2)," security researchers  Asheer Malhotra and Brandon White said in a report shared with The Hacker News ahead of publication. "The C2 hosts a web-based graphical user interface (GUI) titled 'NEXUS Listener' that can be used to view s...

Cisco has released updates to address a critical security flaw in the Integrated Management Controller (IMC) that, if successfully exploited, could allow an unauthenticated, remote attacker to bypass authentication and gain access to the system with elevated privileges. The vulnerability, tracked as CVE-2026-20093, carries a CVSS score of 9.8 out of a maximum of 10.0. "This vulnerability is due to incorrect handling of password change requests," Cisco said in an advisory released Wednesday. "An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device." "A successful exploit could allow the attacker to bypass authentication, alter the passwords of any user on the system, including an Admin user, and gain access to the system as that user." Security researcher "jyh" has been credited with discovering and reporting the vulnerability. The shortcoming affects the following products regardless of the dev...

The latest ThreatsDay Bulletin is basically a cheat sheet for everything breaking on the internet right now. No corporate fluff or boring lectures here, just a quick and honest look at the messy reality of keeping systems safe this week. Things are moving fast. The list includes researchers chaining small bugs together to create massive backdoors, old software flaws coming back to haunt us, and some very clever new tricks that let attackers bypass security logs entirely without leaving a trace. We are also seeing sketchier traffic on the underground and the usual supply chain mess, where one bad piece of code threatens thousands of apps. It is definitely worth a quick scan before you log off for the day, if only to make sure none of this is sitting in your own network. Let's get into it. Pre-auth RCE chain exposed Security Flaws in Progress ShareFile watchTower Labs has disclosed two securi...
