PoC Exploit Released for Microsoft Windows Error Reporting ALPC Privilege Escalation

A proof-of-concept exploit for CVE-2026-20817, a local privilege escalation vulnerability in the Windows Error Reporting (WER) service, has been released by security researcher oxfemale on GitHub. This vulnerability allows low-privileged users to gain SYSTEM-level access through crafted Advanced Local Procedure Call (ALPC) messages. The flaw is located in the WER service's SvcElevatedLaunch method, which fails to validate caller privileges before executing WerFault.exe with user-supplied command line parameters. The CVSS v3.1 base score for this vulnerability is 7.8, indicating a high severity level. It affects unpatched versions of Windows 10, Windows 11, Windows Server 2019, and Windows Server 2022 prior to the January 2026 update. Demonstrations have shown successful exploitation on Windows 11 23H2. Security teams are advised to monitor for unusual processes related to WerFault.exe, investigate missing SeTcbPrivilege in SYSTEM tokens, and review WER-related activities from low-privilege users. Immediate application of the January 2026 security patches is recommended, and a temporary workaround involves disabling the WER service.

PoC Exploit Released for Windows Error Reporting ALPC Privilege Escalation

A critical local privilege escalation vulnerability, tracked as CVE-2026-20817, affects Microsoft Windows through the Windows Error Reporting (WER) service. This flaw allows authenticated users with low-level privileges to execute arbitrary code with full SYSTEM privileges. The vulnerability resides in the SvcElevatedLaunch method (0x0D) and fails to validate user permissions, enabling attackers to launch WerFault.exe with malicious command-line parameters from a shared memory block. The exploit affects all versions of Windows 10 and Windows 11 prior to January 2026, as well as Windows Server 2019 and 2022. Microsoft addressed this vulnerability in the January 2026 Security Update. Organizations are advised to apply security patches and monitor for unusual WerFault.exe processes.

Replicate spatial data using AWS DMS and Amazon RDS for PostgreSQL

The process of migrating spatial data from self-managed PostgreSQL, Amazon RDS for PostgreSQL, or Amazon Aurora PostgreSQL-Compatible Edition to Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL-Compatible Edition using AWS Database Migration Service (AWS DMS) is outlined. Spatial data includes points, lines, polygons, and collections of these features, which are essential for applications like mapping and asset tracking. AWS DMS treats spatial columns as large objects (LOBs) and requires proper configuration for LOB handling and PostGIS support to avoid migration failures. PostGIS is an extension for PostgreSQL that manages geospatial data types and functions, enabling operations such as radius searches and distance calculations. Amazon RDS for PostgreSQL fully integrates with PostGIS, making it suitable for geospatial applications. The migration solution involves ensuring compatibility of PostGIS versions between source and target databases, configuring AWS DMS, and validating the migration. Prerequisites include having an AWS account, RDS instances for source and target, a DMS replication instance, and the PostGIS extension installed on both databases. Tables must have primary or unique key constraints, and geometry columns must be nullable for LOB handling. Best practices for configuring PostGIS include validating version compatibility, monitoring resource usage, and establishing backup strategies. Implementation steps involve creating a spatial table in the source database, preparing the target database, configuring the AWS DMS task with specific settings, and monitoring the migration process through CloudWatch logs. Common errors during replication may relate to LOB handling or PostGIS data types. Post-migration validation includes comparing row counts, verifying geometry data types, and ensuring the functionality of PostGIS spatial functions. Finally, it is recommended to clean up all resources post-migration to avoid ongoing charges.

Android 17 Beta 2 gives apps a way to access contacts, display color securely

Google has released Android 17 Beta 2, which includes features aimed at enhancing user privacy. The update introduces a limited-access contacts picker that allows apps to access specific contacts based on user-selected data fields, employing a temporary, session-based read access model. This reduces the need for broad READ_CONTACTS permissions and allows users to choose which contacts to share. Additionally, the EyeDropper API is introduced, enabling apps to collect display color data without requiring screen capture permissions, thus enhancing security. Both features are designed to give users greater control over their personal information.

How Your Android Apps Keep Talking — Even When You’re Not Using Them

When connecting to public Wi-Fi, using a VPN is essential as it encrypts traffic and creates a secure tunnel between the device and a remote server, keeping activities concealed from the local network. Android devices continuously communicate in the background, performing tasks such as updating emails and syncing notes, which increases data visibility on public networks. Public Wi-Fi has become common due to remote work and shared spaces, leading to increased privacy risks as smartphones now store sensitive information like banking apps and personal photos. Users are encouraged to adopt simple security habits, including using a VPN when connecting to public networks. Android devices are always connected, making network-level protection important to safeguard background communications.

How to migrate applications to Windows 11

Organizations are transitioning from Windows 10 to Windows 11 following the end-of-support date for Windows 10. Windows 11 is designed to support most applications that ran on Windows 10, but challenges may arise due to undocumented legacy applications and configurations. A thorough evaluation of devices, including installed applications and data locations, is essential to minimize disruptions during the upgrade. Migrations can be categorized as clean installations or in-place upgrades. A clean installation erases the previous OS and data, while an in-place upgrade retains existing settings and applications. In-place upgrades are not allowed for certain transitions, such as from Windows 10 Home to Windows 11 Pro without first upgrading to Windows 10 Pro. IT professionals often prefer clean installations to avoid carrying over issues from the previous OS. During an in-place upgrade, data in library folders is retained, but data in the Windows folder may be at risk. Compatibility issues may arise with poorly designed applications or drivers post-upgrade, particularly with legacy applications reliant on outdated frameworks. Preparation for migration includes creating an inventory of applications, identifying potential incompatibilities, and ensuring backups of data. IT must also confirm hardware meets Windows 11 requirements. If a clean installation is chosen, strategies for application installation must be developed, utilizing tools like System Center Configuration Manager or Microsoft Intune. Validation and testing of migration tools should occur in a lab environment, followed by a pilot deployment on a small percentage of machines. After successful pilot testing, the final deployment can proceed, followed by an audit to address any issues. Careful planning and testing are crucial for a smooth migration process.
