Microsoft has patched a maximum-severity vulnerability in the Entra ID identity and access management (IAM) platform that has been exploited in attacks.
Toronto's Hospital for Sick Children (SickKids) says a cybersecurity incident exposed the personal information of some current and former employees and job applicants, stemming from a flaw in third-party software. Clinical systems and patient records were not affected. (264)
GitLab flaw CVE-2026-19478 is now under active exploitation, allowing unauthenticated attackers to modify or delete public projects. WatchTowr researchers warn of active exploitation of critical GitLab flaw CVE-2026-19478 (CVSS score of 9.4). This week, GitLab pushed out an emergency patch to address this flaw, which could let an attacker with zero credentials remotely modify or delete public projects and user data. “GitLab has remediated an issue that under certain conditions could allow an unauthenticated user to remotely modify or delete public projects and user data via a GraphQL directive.” reads the advisory. GitLab issued an emergency patch on August 17, five days after its regular update. The vulnerability impacts only self-managed installations, users should upgrade to versions 19.2.4, 19.1.6, 19.0.8, and 18.11.11. There’s a gap worth flagging for anyone still sitting on an older release. The available patches don’t cover the 18.2 through 18.10 branches, even though those versions technically fall inside the affected range. If you’re running anything in that window, staying put isn’t really an option; you’ll need to upgrade to a patched branch entirely rather than waiting for a fix that isn’t coming for your current one. hiimguardian reported the flaw through the company HackerOne bug bounty program. Organizations should urgently patch internet-facing GitLab servers. Until they can update, they should restrict unauthenticated access to /api/graphql, disable public repositories where possible, and check logs for requests containing @gl_introduced.

Microsoft on Thursday warned of a maximum-severity security flaw in Entra ID that it said has been exploited in the wild, but noted that no customer action is required. The vulnerability, tracked as CVE-2026-69836 (CVSS score: 10.0), is a case of remote code execution impacting the tech giant's cloud-based identity and access management service. It was previously called Azure Active Directory
AI is making phishing attacks more personalized, convincing, and difficult for traditional email filters to detect. Kaseya explains how MSPs can monitor identity, email, and endpoint activity to detect and contain attacks that make it past the inbox.
The Cybersecurity and Infrastructure Security Agency (CISA) warned federal agencies that threat actors are now exploiting a critical MLflow vulnerability. MLflow is an open-source AI engineering platform for large language models (LLMs) and agents backed by the Linux Foundation, with over 30 million monthly downloads, used by thousands of organizations to debug, evaluate, optimize, and monitor AI applications. Tracked as CVE-2026-64849, this critical DNS-rebinding server-side request forgery (SSRF) bypass in MLflow's outbound webhook delivery was patched in version 3.15.0 and can be used by attackers without privileges to remotely access internal services or cloud metadata configurations on unpatched instances. "The default MLflow Tracking Server (mlflow server, no authentication, default SQLite backend) exposes the model-registry webhooks API unauthenticated, including a synchronous POST /api/2.0/mlflow/webhooks/{id}/test endpoint that returns the upstream response status and body to the caller," MLflow's security team says in a security advisory issued three weeks ago.

Three distinct suspected Russian cyber espionage threat clusters have been observed leveraging legitimate authentication flows to single out individuals working in academia, aerospace and defense, governments, and think tanks across Europe, as well as academia and think tanks within the U.S. These clusters include UNC6293, UNC7005, and UNC5976. "These clusters engage in persistent, adaptive
Citrix has released updates to address two security flaws impacting NetScaler ADC and NetScaler Gateway deployments, including a critical-severity authentication bypass vulnerability. According to the cloud computing and virtualization technology company, the issues affect customer-managed NetScaler ADC and NetScaler Gateway, including certain FIPS and NDcPP builds, as well as SecurAccess
In a large-scale campaign that researchers dubbed CameraSwarm, hackers compromised more than 14,500 Dahua IP cameras mostly in Ukraine and Russia. The operation ran for at least 35 days between June 17 and July 22, compromising devices by exploiting vulnerabilities, brute-forcing logins, and using offline recovery codes from serial numbers for cloud-registered cameras. Researchers at threat intelligence company Hunt.io discovered the campaign after finding a working directory on an HTTP server that the operator left unprotected. Hunt.io recovered 407 MB of data comprising 2,616 files across 234 directories, including source code, logs, credentials, captured camera images, shell history, and exploitation results, which helped them map an impressive operation. According to their findings, the 35-day CameraSwarm campaign compromised 14,530 Dahua IP cameras using three attack methods in parallel:
