A critical security flaw in Issabel Framework, a web-based framework for the open-source unified communications PBX software, has come under active exploitation.
The vulnerability in question is CVE-2026-89026 (CVSS v3.1 score: 9.8/CVSS v4.0 score: 9.3), which can allow an unauthenticated remote attacker to execute arbitrary operating system (OS) commands by taking advantage of a hard-coded
Enterprises in Russia have emerged as the target of three threat activity clusters tracked as NightEagle, Hacking Cat, and Toy Ghouls, according to multiple reports from Kaspersky.
The cybersecurity vendor said it has identified attacks mounted by NightEagle (aka APT-Q-95), a threat actor known to be active since at least 2023, that involve new techniques for persistence and lateral movement.
Security researchers at Forever Security have shown that one ordinary browser extension could take control of the AI assistants built into five Chromium-based products: Gemini Live in Chrome, Perplexity Comet, Microsoft Edge, Opera Neon and the Claude in Chrome extension.
Once the extension was installed, it could access each product's built-in AI with a single click. On Comet, Edge,
Mandiant says an attacker hijacked an active AI coding-assistant session at an unnamed software-as-a-service provider and later spread Shai-Hulud across about 100 internal code repositories.
Before the repository spread, the assistant recommended software that the attacker had poisoned, and the recommendation was accepted. The worm stole repository secrets and source code for the
Parallels Desktop for Mac has a flaw that lets an ordinary local account run code as root, the highest level of access on a Mac, software company JFrog said this week.
The attack needs code already running on the machine as a normal user, so it does not work over the network. JFrog says the fix is in Parallels Desktop 27, a version that Intel Macs cannot install.

N0va is targeting organizations across North America and Europe with phishing campaigns that impersonate trusted services and abuse legitimate authentication flows. Successful attacks can give threat actors access to valid accounts without relying on obvious malware activity.
From there, a single compromised identity can open the door to sensitive data, business systems, and additional cloud
Google has disclosed that a high-severity security flaw in its Pixel Cellular Modem has come under exploitation in the wild.
The vulnerability, tracked as CVE-2026-58704 (CVSS score: 8.0), is a privilege escalation flaw.
"In Cellular Modem, there is a possible permission bypass due to a logic error in the code," according to a description of the bug in the NIST National Vulnerability Database
A leaked credential shows up in a criminal marketplace, or a vulnerability gets a disclosure advisory, and either one can be weaponized against a real target before most security teams have triaged the alert. Attackers are combining that kind of intelligence with AI-assisted exploitation to accelerate the path from exposure to breach faster than most security programs are built to react.
Acronis has warned that a high-severity security flaw in its Backup plugin for cPanel and Web Host Manager (WHM) deployments has been exploited in the wild.
The vulnerability, tracked as CVE-2026-87886 (CVSS score: 7.8), is described as a case of local privilege escalation due to insecure file permissions. It affects the following versions -
Acronis Backup plugin for cPanel & WHM (Linux
Threat actors are exploiting a critical security flaw in WooCommerce Wholesale Lead Capture, a premium WordPress plugin that has more than 6,000 active installs.
"This vulnerability can be leveraged by unauthenticated attackers to upload arbitrary files, including PHP backdoors, and achieve remote code execution," Wordfence said.
The WordPress security company said it has blocked over
A critical security flaw in WSO2 API Manager has come under active exploitation in the wild, according to findings from watchTowr.
The vulnerability, tracked as CVE-2026-5430 (CVSS score: 9.8/10.0), is a case of improper verification of a cryptographic signature that could result in account takeover. Hacktron Team has been credited with discovering and reporting the flaw.

Cybersecurity researchers have shed light on a previously undocumented Brazilian banking malware operation that delivers a toolkit called KREMLIN.
Elastic Security Labs is tracking the activity under the moniker REF9334. Active since at least May 2025, the threat actor has used lures that impersonate a dozen Brazilian banks and install a malicious browser extension on Google Chrome and
Cybersecurity agencies in the United States, the United Kingdom, and the Netherlands have detailed a Windows malware that they say Iran's intelligence service uses to spy on dissidents, journalists, and activists around the world.
The malware is controlled via the Telegram messaging app and can copy a target's emails and chat messages, take screenshots, and activate the microphone to record
Cybersecurity researchers have disclosed details of a multi-platform campaign that uses the Message Queueing Telemetry Transport (MQTT) protocol as a communication channel to control Windows and Linux systems.
The emerging malware family, codenamed BambooToken, is assessed to be active since at least February 2023 and put to use in attacks targeting organizations across Asia and South America.
With artificial intelligence (AI) shrinking the window between vulnerability discovery and exploitation and lowering the barrier to entry for bad actors, new findings from Sysdig show that skilled human operators can move just as swiftly after gaining initial access.
In one instance highlighted by the cloud security company, the threat actor pivoted from a vulnerable Marimo notebook to an SSH
Introduction
Security teams have gotten pretty good at testing against what can hurt them. Can this EDR agent catch this payload? Will my organization fail the phishing simulation? Does this SIEM rule fire on this particular technique? And, in more mature organizations, this testing happens continuously rather than as a one-off exercise.
But no matter how much you validate against these
Cybersecurity researchers have disclosed details of a mass-scanning campaign that has targeted Vite deployments siphon sensitive data.
The first is an automated effort aimed at internet-exposed Vite development servers that's designed to steal cloud credentials, configurations from Amazon Web Services (AWS) and Microsoft Azure instances, and infrastructure state files, per F5 Labs.

A critical vulnerability in LiteSpeed Web Server Enterprise could let a low-privilege website user gain root access on a shared-hosting server, cPanel warned in an advisory published on September 14.
On such servers, many customers' sites run on a single machine, and an attacker with one of those hosting accounts could exploit the flaw to access or alter other sites and the server itself,
Cisco has warned that a new critical vulnerability impacting AsyncOS Software for Cisco Secure Email Gateway has come under active exploitation in the wild.
The vulnerability, tracked as CVE-2026-76461, carries a CVSS score of 9.8 out of a maximum of 10.0. It has been described as a case of insufficient validation in the email parsing logic that could allow an unauthenticated, remote attacker
A Chinese threat actor has been attributed to a spear-phishing campaign that exploits recently patched security flaws in Google Chrome and Microsoft Windows to deliver a malicious JavaScript backdoor called GRIMWEDGE.
