SonicWall has released hotfixes for four flaws in its SMA1000 appliances, the gateways that give remote workers access to a company's network and applications. The most serious could allow an attacker without a login to send requests through the appliance and reach internal functions. SonicWall rates it 10.0 on the CVSS scale and says it has no evidence that any of the four flaws is being

A critical vulnerability in LMCache, open-source software that speeds up large language model (LLM) servers such as vLLM, lets an attacker run code on the cache server without logging in, and no fixed version is available. The flaw is in LMCache's multiprocess mode, where the cache runs as a standalone server that LLM workers reach over the ZeroMQ messaging library. A single network

A malicious spreadsheet can make LibreOffice and Apache OpenOffice run an attacker's code as soon as the file is opened, security researchers have shown. There is no warning first, of the kind either program shows before it runs a macro. The attack works only when the program's Java support is enabled. So far, it has only been shown as a proof of concept, and there are no reports of its use in

Google has stopped accepting product vulnerability reports through its bug bounty program for its open-source software. The change, in effect since October 1, means researchers can no longer submit security flaws in the code of projects such as Go, Angular, and Protocol Buffers there for a reward. Reports about supply chain compromises are still accepted, and reports filed before October 1 are

A critical flaw in 8 Atlassian Data Center products, which customers host themselves, allows an attacker with no login access to read specific files in each product's web application root directory. The attacker must already know a file's exact name and path and cannot list what the directory holds. Atlassian disclosed the flaw, CVE-2026-21589, on October 5, rated it 9.3 out of 10, and

Unauthorized parties have gained access to the names, addresses, and personal identification numbers of about 8.8 million people, living and dead, in Denmark's national population register, the country's digitalization ministry said on October 5. They used a private Danish company's lawful right to look up records in the Central Person Register (CPR). The ministry has told people never to

A critical flaw in GitLab's AI Gateway could let a logged-in user with Duo Agent Platform access run commands on the gateway under certain conditions, GitLab said in an advisory. The gateway is the service that connects a GitLab instance to AI models, and only organizations that host their own gateway need to act. The flaw is fixed in gateway versions 19.2.4, 19.3.2, and 19.4.1. The flaw

Police in Spain have arrested a 16-year-old whom investigators suspect of running the KillSec ransomware group. KillSec is accused of stealing data from organizations and threatening to publish it on its leak site unless they paid. The 16-year-old was one of 3 people arrested on September 30, when police also took control of that site. Investigators identified him as KillSec's suspected

Security researchers have published the first public proof-of-concept for CVE-2026-86950, an Apple CoreGraphics flaw Apple says may have been used in attacks against specific targeted individuals. The trigger is a malicious PDF with a crafted embedded font that crashes unpatched iPhones and Macs. The code causes a crash, not an execution error. Turning the memory corruption into a working

Attackers are exploiting a new critical zero-day flaw in Cisco Catalyst SD-WAN Manager, the system companies use to manage their Cisco SD-WAN networks, Cisco said in an advisory on September 30. The flaw, CVE-2026-76504, could allow a remote attacker with no login access to use the Manager's API as the admin user. Fixed releases are available, and there is no workaround. It carries a

AI coding agents asked to share screenshots of code changes for review have put internal company images in public GitHub repositories, security company Glow said. Its researchers found more than 13,000 internal images from developers at over 300 organizations, including customer billing records and screens of features not yet released. In most cases, they sat under developers' personal accounts

A High-severity OpenSSL flaw can leak heap memory to the other side of a DTLS connection or crash the program, OpenSSL said on September 29 as it released fixes. DTLS, the TLS variant used for UDP traffic, resends a handshake message if no reply arrives before the timer expires. The leak or crash can happen when such a resend starts while a larger handshake message is stuck part-way

An attacker used stolen passwords of staff at France's tax administration to take tax data on hundreds of thousands of taxpayers and businesses in June and July. Neither the tax administration nor France's national cybersecurity agency saw the data leave. The attack was not sophisticated, the agency, ANSSI, says in a report (in French) published on Tuesday: it worked because of weak

Russian state hackers known as Star Blizzard have been using fake event invitations to trick people into installing a backdoor on their Windows computers, according to Microsoft. The campaigns, aimed at people and organizations tied to Ukraine, have affected more than 100 organizations since January, mostly in the U.S. and U.K. At least one computer was infected, but the number of breached

A malicious MCP server could trick an application built on the official MCP Python SDK into handing over the OAuth credentials it uses to log in to a real service, the SDK's maintainers said in a security advisory. Affected versions sent the client secret, the authorization code, and the PKCE proof key to a token endpoint the attacker controlled. The fix is in versions 1.30.0 and

Hackers have used a malware family called NeedyMantis to maintain long-term access to networks they had already breached, Microsoft said in a technical analysis. The malware has been seen in a small number of targeted intrusions at telecommunications organizations, universities, medical nonprofits, intergovernmental organizations, and government contractors. Its use goes back to at least

The attacker who stole about $388 million from the cryptocurrency exchange Bitget gained access through a vulnerability in a third-party security product the exchange used, Bitget said on Monday. The attacker exploited the flaw to obtain high-level internal credentials and then, on September 24, used them to send fraudulent withdrawal commands to Bitget's wallet system. Exchanges keep most

RatHat's operators build and publish the Android banking trojan and control infected phones from a web console, according to security company Cleafy. Cleafy has traced nearly 100 deployments of that console since April 2026. It said this fits a malware-as-a-service model, in which each customer runs a separate copy. The console stores what the malware collects from each phone,

Two critical vulnerabilities in Citrix NetScaler ADC and NetScaler Gateway that allow remote code execution have been exploited in the wild, Citrix confirmed on September 27. It released fixes for both, along with six other flaws. One of the two affects every deployment on an affected version, including those in the default configuration. The bulletin came a day after security firm watchTowr

A flaw in Cloudflare Containers let a paying customer read data that other customers' containers had left behind on the same server, Cloudflare and the researchers who found it said on Thursday. The data came from disk space that earlier containers had used and given up, not from any live workload, and an attacker could not choose whose data they got, according to Cloudflare. The company
