A flaw was found in libvirt. During storage volume clone or convert operations, newly created volume images were temporarily world-readable. This was caused by the `qemu-img` utility running with overly permissive file creation settings, allowing any local user to read the full guest disk contents. This vulnerability could lead to sensitive information disclosure from guest virtual machines.

——0Improper access control in the IRP_MJ_WRITE command interface in
Wellbia XIGNCODE3 xhunter2.sys, version 2026.6.1.192, allows a local, unprivileged attacker to achieve local privilege escalation to
NT AUTHORITY\SYSTEM, extract credentials from PPL-protected
lsass.exe, and terminate PPL-protected security processes.7dCVE-2026-685635.5 MED1.0%
——0A flaw was found in ansible-collection-redhat-leapp. When a remediation task is executed with elevated privileges and the `leapp_old_postgresql_data` option is selected, a PostgreSQL data backup archive is created with insecure permissions. This allows a local non-root user on the managed node to read sensitive archived PostgreSQL data, leading to information disclosure.7dCVE-2026-48499—14.8%
——4Activepieces is an open source AI workflow automation platform. Prior to 0.84.0, an unsanitized path segment in the Code piece sandbox can let an authenticated flow author reach read-write cached flow and code files belonging to other tenants on the same worker, exposing embedded data and allowing modified code to execute on a victim tenant's next flow run. This issue is fixed in version 0.84.0.11dCVE-2026-647075.5 MED2.1%
——1A permissions issue was addressed with improved validation. This issue is fixed in iOS 26.6 and iPadOS 26.6, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6, visionOS 26.6. An app may be able to delete files for which it does not have permission.13dCVE-2026-618928.8 ALT19.5%

——1Duplicati v2.3.0.1 backup software gives Authenticated Users MODIFY permissions that propagate to all subdirectories. Installing the software outside of the Program Files directory, or on a custom path, creates a LocalSystem service running from a directory that any standard local user can write to. A standard local user can overwrite any DLL in the service directory. On service restart, the OS loads the attacker's DLL before any managed code runs, executing arbitrary code as SYSTEM.14d
