Attackers are exploiting a critical flaw in Cisco Secure Email Gateway that lets a sender with no login write files to the appliance's operating system, Cisco said in an advisory on Wednesday. The attacker sends an email with a crafted attachment through the gateway and, if it succeeds, could then run commands as root. The appliance filters an organization's email for spam, malware,

Attackers exploited a flaw in an optional Nextcloud app, Collabora Online - Built-in CODE Server, to plant web shells on Nextcloud servers. Three administrators reported the issue on GitHub, with the first logged attack on September 10. A web shell is a small file that executes any command an attacker sends via a web request, with the rights of the web server account. The flaw

A flaw in how curl handles HTTP/2 uploads lets a malicious server receiving an upload corrupt the client's memory, and the researcher who reported it turned that into code execution on the uploading machine. The curl project fixed it on October 14 in curl 8.23.0. Taking over a client needs exact knowledge of its build and memory layout, and curl expects a real attack to end in a crash

A team at security firm XBOW chained three then-unknown Google Chrome bugs into a single attack that runs code on a Windows computer when the user only loads a web page, the company said. Its researchers built the attack in six days by directing AI agents running OpenAI's publicly available GPT-5.6 Sol model. Google has since confirmed all three bugs, fixed them, and paid XBOW its top $

A flaw in Linux's vhost subsystem lets a local user read and write kernel memory at will and become root across nearly a decade of kernel versions. In one virtualization setup, it lets an untrusted virtual machine write to the host's memory and hijack the program that runs the virtual machine. The bug is tracked as CVE-2026-74580 and named Vghost. Tencent Zhuque Lab, which found the

Security researchers ran their own code inside a protected part of Windows that is meant to stay sealed off even when the rest of the computer is taken over. The protected area is a VBS enclave, an isolated slice of memory the operating system uses to guard secrets, and the one they broke into handles passwords for a Windows anti-phishing feature. The work was done in a lab as a proof of

A flaw in Docker Hub, the registry where container images are published and downloaded, let one user push, pull, or delete images as another user. Docker fixed the flaw on September 30 and says it found no evidence that anyone exploited it. The flaw was in the feature that converts a personal account into an organization, Docker said in a security advisory on October 12.

An attacker chained three zero-day flaws in Ivanti Connect Secure, a VPN appliance, to run commands as root without logging in, security firm Volexity said on October 13. Ivanti has released fixes for two of the flaws and told customers on affected versions to "act immediately." A fix for the third is still pending, according to Volexity. Volexity, which reported the flaws to Ivanti,

A flaw in SAP's Cloud SDK for Python can send an application's OAuth2 client credentials to a server an attacker controls, SAP said in a security advisory on October 13. The flaw affects multi-tenant applications on SAP Business Technology Platform (BTP) that use the SDK, SAP's official Python client for BTP services. An attacker must be able to control the tenant subdomain,

Three vulnerabilities in LG's webOS can be chained to give an attacker on the same local network root access to certain smart TVs without a PIN or any interaction from the owner. LG has issued a fix, according to an advisory published by SSD Secure Disclosure on October 12. The chain was tested on two TV models, the 32LQ636BPSA and the 27TQ600SW, running webOS 7.5.7-25 on firmware

Attackers took remote control of fridges and freezers at hundreds of French supermarkets on the night of October 11 and warmed them, forcing stores to throw food away, several retail chains said. The attackers reached them through the controller that runs all of a store's fridges and freezers, a device made by Danish company Danfoss that maintenance firms can manage remotely. Les Mousquetaires

Two of 31 newly disclosed flaws in Progress Software's MarkLogic Server database could let an account given only some management privileges take administrator control of the server, the company says. Progress published all 31 on October 12 and scored five of them critical. Fixes have been available since September 10, in MarkLogic 11.3.7 and MarkLogic 12.1.0. Affected

The FBI has arrested another suspected co-conspirator of ShinyHunters, FBI Director Kash Patel said on October 9 in a post on X. ShinyHunters is the extortion group that said in September it had breached the FBI's jobs portal and stolen sensitive data on almost all FBI agents and job applicants. The FBI has not named the suspect, and no charges have been made public. The

Four more U.S. states sued router maker TP-Link Systems on October 6, bringing the total to five, with  Texas filing a suit in February. Florida, Iowa, Montana and Nebraska allege the California company misled buyers about how secure its routers are and how separate it is from China. TP-Link denies the claims and says it will fight them in court. TP-Link Systems is based in

Security researchers have published a full working exploit for a pre-authentication remote code execution flaw in AnyDesk Linux that gives attackers root access before anyone approves the connection. AnyDesk patched the flaw in version 8.0.3 in June, but its changelog described the fix only as "fixed a bug that could lead to a crash," with no CVE assigned and no security

A bug in GoBalance, a tool many dark-web sites use to stay reachable during attacks, lets anyone work out the secret key that controls a site's .onion address using only public information, and then take that address over. Searchlight Cyber, which disclosed the flaw on October 8, says an attacker who recovers the key can redirect the site's visitors to a copy of the site they control.

Three research teams broke into Google's Pixel 10 on October 8 at Pwn2Own Ireland, a hacking contest in Cork whose rules require every target to be fully patched. The contest pays researchers to show working exploits and passes the flaws to the vendors. One of the three Pixel exploits earned Ikotas Labs $300,000, the contest's top prize, and made the team the overall winner. Trend Micro's Zero

Hackers tied to a Chinese cybersecurity company stole email from government organizations, law enforcement agencies, healthcare systems, and religious institutions in Southeast Asia, the FBI and agencies in 6 other countries said on October 8. The company, Integrity Technology Group, has been sanctioned by the U.S. and the UK. The hackers scanned websites for flaws using a tool containing more

Attackers behind a string of personal data leaks at Japanese organizations have abused APIs for mobile apps and targeted known software flaws, the JPCERT Coordination Center (JPCERT/CC) said. The Tokyo-based center, which takes incident reports, based its October 8, 2026 alert on those reports and other information. The alert names no attacker and no affected organization. JPCERT/

The U.S. State Department is offering up to $10 million for information leading to the identification or location of Zhang Yu, a Chinese national charged in the United States in connection with the 2021 Microsoft Exchange Server attacks known as HAFNIUM. The reward is for information leading to his identification or location, the news outlet NTD reported this week, citing a notice
