A critical authentication bypass vulnerability in Xen Orchestra is being actively exploited in attacks that could grant administrator privileges and allow takeover of XCP-ng virtualization hosts. Xen Orchestra is a web-based management platform developed by French software company Vates, used to manage XCP-ng virtualization environments, including virtual machines, hosts, and pools. The vulnerability, tracked as VSA-2026-062, affects Xen Orchestra and the Xen Orchestra Appliance (XOA) and allows remote attackers with network access to the management interface to bypass authentication using a specially crafted cookie. A CVE identifier and CVSS score have not been assigned yet. According to a Vates security advisory, the flaw stems from how Xen Orchestra processes authentication tokens sent through REST API requests.
Recovering from ransomware doesn't guarantee an MSP will retain its clients, especially when delays, poor communication, and unexpected costs undermine trust. Kaseya examines how disconnected recovery tools create these problems and how integrated workflows can improve response times, transparency, and client retention.
SAP patched 35 vulnerabilities in its November 2026 security updates, including four maximum-severity issues affecting its NetWeaver, Web Dispatcher, and Gateway software. The company addressed memory corruption (CVE-2026-76964) and missing authentication (CVE-2026-120017) flaws in the NetWeaver Application Server ABAP's Internet Communication Manager and SAML2 Service Provider components. NetWeaver is the core app platform that underpins SAP's business software and handles application integration, authentication, user management, and data processing. The other two maximum severity vulnerabilities stem from a broken access control weakness (CVE-2026-89103) in SAP Gateway and a memory corruption issue (CVE-2026-89126) in SAP Web Dispatcher. Gateway is a core framework that enables external apps to securely connect to SAP backend systems, while Web Dispatcher (deployed in almost every enterprise SAP environment) is a specialized component that acts as a load balancer and reverse proxy for web requests entering an SAP system architecture.
Cybersecurity company Barracuda Networks warned that attackers have begun exploiting two recently patched Email Security Gateway (ESG) vulnerabilities that let them run commands with root privileges. Barracuda released security updates to address the two flaws (tracked as CVE-2026-116606 and CVE-2026-111560) one week ago. The first stems from an Email Security Gateway (ESG) authentication weakness that can be exploited to modify an appliance's global configuration, while the second lets unauthenticated attackers inject OS commands that execute with root privileges. Barracuda also said that successful attacks require access to the administrative user interface (Admin UI) of targeted devices and advised customers to restrict access to trusted internal networks and use appropriate network access controls to limit exposure.
AI infrastructure startup Fireworks has disclosed a new security breach in which attackers accessed its development machines after breaching a third-party cloud provider. FireWorks provides a high-performance inference platform for developers who want to deploy and run open-source artificial intelligence models (such as Mistral, Meta's Llama, or Google's Gemma) without worrying about hardware bottlenecks and complex infrastructure tasks. The company notified law enforcement and customers of another security incident in early October after attackers accessed environment variables containing API keys and tokens stored as secrets for a limited number of accounts. "The evidence indicates links to a cybercriminal threat actor group, which is financially motivated and aimed at selling tokens from unauthorized access to Large Language Models (LLMs) to illicit routing gateways, known as 'LLMJacking'," Fireworks said at the time.
Iris Ohyama warns that a cloud data breach may have exposed personal information of 7.7 million customers, including names and passwords. Japanese household goods manufacturer Iris Ohyama has disclosed that attackers may have accessed personal information belonging to approximately 7.7 million people through an external cloud service used by its online shopping subsidiary, Iris Plaza. The incident highlights a security risk that often receives less attention than attacks against corporate networks: sensitive customer information can be exposed through services operated outside an organization’s own infrastructure. Iris Plaza discovered a suspicious file in an external cloud service on October 28, 2026. The company immediately shut down its online shopping platform and related systems, launched an investigation and confirmed unauthorized access by a third party. It published an initial notification on October 29, followed by an update on November 5 detailing the potential impact. In its official incident notice, the company confirmed that information stored in the external cloud environment may have been accessed or obtained by unauthorized parties. “Iris Plaza Co., Ltd. (Headquarters: Sendai City, Miyagi Prefecture, President: Ryota Iwasaki, hereinafter referred to as “the Company”), a member of the Iris Group, has investigated the unauthorized access incident that occurred on its official online shopping site for Iris Ohyama, “Iris Plaza” (hereinafter referred to as “Iris Plaza”). As a result of the investigation, it has been determined that some personal information may have been leaked.” reads the company’s notice. “Subsequent investigations have confirmed the possibility that data stored on an external cloud service may have been leaked. The total amount of personal information stored was approximately 7.7 million records, and at this time, we have confirmed the possibility that this data may have been viewed or obtained. “ The 7.7 million figure refers to records stored in the affected cloud service, not confirmed stolen data. Potentially affected individuals include 5.8 million current and former members and 1.9 million non-members. Exposed information may include names, addresses, phone numbers, email addresses, gender, dates of birth and passwords, some of which are encrypted. “The following personal information may have been leaked at this time: classificationTarget itemsNumber of peopleMember data (including information on members who have withdrawn)Name, address, phone number, email address, gender, password * , date of birth, etc.Approximately 5.8 million peopleNon-member data (including information on individuals who have purchased products without registering as a member or who have participated in campaigns)Name, address, phone number, email addressApproximately 1.9 million people Not all of the above information about our customers has been leaked. The items affected vary depending on your registration status.” continues the notice. “Some items, including passwords, are encrypted.” There is one important distinction: credit card information wasn’t stored in the affected cloud service and, according to the company, wasn’t exposed. Iris Plaza also says it hasn’t identified unauthorized access or data leaks involving its stores on other external e-commerce marketplaces. As of November 5, it had received no reports of fraudulent use of the information or financial losses linked to the incident. アイリスオーヤマ株式会社+1 The company reported the incident to Japanese police and the country’s Personal Information Protection Commission on October 29. It also blocked the unauthorized access route, suspended the affected systems and brought in external experts to support the investigation. The response extended beyond the main shopping platform. Iris Plaza suspended its SIMPLE STYLE website, while another group company, Iris Tech Service, stopped its websites and new applications for home appliance subscriptions and furniture and appliance delivery and installation services. The company says it hasn’t found evidence that these additional services were compromised. Iris Plaza has also warned customers about possible follow-up scams. Attackers could use the exposed personal information to create convincing phishing emails, SMS messages or phone calls, impersonating the company or other organizations. Fake websites and social media accounts could also appear, attempting to collect login credentials, payment details or other personal information. The company is asking customers who reused their Iris Plaza passwords on other services to change them. It also says it will contact potentially affected individuals individually as the investigation progresses. Customers should be particularly careful with messages claiming to provide information about the incident, account recovery or compensation. “We will never ask for your password, PIN, authentication code, or any other important information when we contact you.” アイリスオーヤマ株式会社 The incident is another reminder that organizations must extend security controls and monitoring beyond their own infrastructure. Third-party cloud services can hold millions of customer records, and unauthorized access to those environments can create consequences far beyond the service initially compromised.
