The impacted product(s) could be end-of-life (EoL) and/or end-of-service (EoS). Users are advised to discontinue use and/or transition to a supported version.
Linux Kernel contains a race condition vulnerability which allows concurrent writes to the same AF_ALG socket causing data to be unpredictably interleaved and creating inconsistencies in the socket's internal state.
Linux Kernel contains an improper check for unusual or exceptional conditions vulnerability in the TLS receive path which allows a zero-length record retrieved from the rx_list to bypass the intended recvmsg() record-type handling, potentially causing subsequent TLS records to be processed using incorrect zero-copy and queuing assumptions. The impacted product(s) could be end-of-life (EoL) and/or end-of-service (EoS). Users are advised to discontinue use and/or transition to a supported version.
A new Android malware called RatHat has been discovered, targeting users with an AI-powered subsystem that helps operators remotely navigate compromised devices. [...]
A critical vulnerability in Check Point's Security Management and Log Servers could allow an attacker without login credentials to run code as root on those servers over the network. The Security Management Server is the system that controls firewall policy and administrator access. Check Point has released a fix through its LivePatch update channel and says it has no indication that the flaw
AI is making credential theft faster and easier to scale, giving attackers more opportunities to abuse valid identities. Specops explains why identity security must go beyond successful authentication by verifying that both the user and the device requesting access can be trusted. [...]
Every release of the Unbound DNS resolver before 1.26.1 has a critical heap overflow in its DNSSEC validator, maintainer NLnet Labs said in an advisory on Wednesday. An attacker who controls a malicious zone and queries a vulnerable resolver can trigger it, enabling remote code execution. Unbound 1.26.1, released the same day, fixes the bug, tracked as CVE-2026-81642, along with
The China-linked espionage group FamousSparrow has been using a new backdoor named SparroWocky in attacks on government organizations in Latin America. [...]
Anthropic is testing a new personal finance feature called "Claude Money" that will allow you to connect your bank accounts directly to Claude and "understand your money." [...]
Microsoft is investigating reports that the Windows 11 KB5124008 security update is breaking domain trust relationships on some enterprise systems, preventing users from logging in with valid domain credentials. [...]
The consumer data broker Radaris.com has long had a reputation for ignoring requests to remove personal information from its vast empire of people-search services online. That reputation caught up with the company recently in a lawsuit alleging Radaris violated a New Jersey privacy law that provides for hefty fines against data brokers that publish personal information on state law enforcement officials. In the face of repeated stonewalling and prevarication by attorneys for Radaris, the judge in the case ordered that radaris.com and more than a dozen other data broker domains be transferred to the plaintiffs.
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
The ransom itself can be only a fraction of the total cost of a ransomware attack, with downtime, recovery, remediation, and legal obligations adding millions to the bill. Datto explains how a mature BCDR strategy can reduce downtime and provide a faster, more predictable path to recovery. [...]
Microsoft has reminded customers that Windows Server 2022 will reach the end of mainstream support next month and enter extended support until October 2031. [...]
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
Acronis Backup plugin for cPanel & WHM and extension for Plesk contains an incorrect default permissions vulnerability that could allow for privilege escalation.
Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) contain an incorrect use of privileged APIs vulnerability that could allow an unauthenticated, remote attacker to gain unauthorized access to the affected device by bypassing the web-based management interface.
Google Pixel devices contain an improper authorization vulnerability in the cellular modem. A logic error may allow an attacker to bypass permission checks and escalate privileges.
Acronis disclosed a high-severity Linux local privilege escalation vulnerability in its backup plugin for cPanel, WebHost Manager (WHM), and Plesk that may be exploited in the wild. [...]
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
Cisco AsyncOS software for Cisco Secure Email Gateway (SEG) contains a SQL injection vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary commands with root privileges on the underlying operating system.
GitLab Community Edition and Enterprise Edition contains a path traversal vulnerability that allows an unauthenticated user to read arbitrary files due to an improper path confinement and missing authentication enforcement in the repository commits API.
ConnectWise ScreenConnect contains both an improper privilege management and missing authorization vulnerability that may allow an attacker to file transfer and execution through an active remote sessions without authorization or host confirmation.
JFrog Artifactory contains an improper authentication vulnerability that could return an internal anonymous-user token to an unauthenticated caller when anonymous access is disabled, potentially exposing sensitive resources.
JFrog Artifactory contains an incorrect authorization vulnerability that allows leads to privilege escalation attack due to a validation check of the token signature/issuer and not the token’s scope.
MikroTik RouterOS contains an improper neutralization of argument delimiters in a command vulnerability which allows an attacked to change the trusted RouterOS policy mask, leading to privilege escalation.
MikroTik RouterOS contains a missing authenticaion for critical function vulnerability which allows kernel memory disclosure and denial of service in the btest service.
Citrix NetScaler ADC and NetScaler Gateway contain an authentication-bypass vulnerability involving an alternate path or channel. When the NetScaler appliance is configured as an AAA virtual server or as a Gateway (SSL VPN, ICA Proxy, CVPN, or RDP Proxy), an unauthenticated remote threat actor may be able to bypass authentication.
Microsoft Corp. today issued updates to plug at least 974 security holes in its Windows operating systems and other software, by far its biggest single patch batch ever. Microsoft says artificial intelligence is helping to speed the discovery of vulnerabilities, but security experts warn that many organizations already are struggling to prioritize the more human-intensive endeavor of testing and deploying so many fixes each month.
