12-Year-Old PostgreSQL Vulnerability Enables Database, Server Takeover

A significant vulnerability in PostgreSQL, tracked as CVE-2026-6471, has been identified by cybersecurity firm Cyera. This flaw, present since 2014, allows attackers with minimal privileges to potentially take control of databases and servers. The vulnerability, known as PostGREShell, has a CVSS score of 7.2 and can be exploited for remote code execution and privilege escalation due to a missing authorization in the database's logical decoding mechanism. Attackers with 'Replication' privileges can load arbitrary files through the logical decoding plugin, executing code with the privileges of the postgres system user. This can lead to the elevation of privileges to superuser status, granting unrestricted access to all tables and the ability to execute operating system commands. All PostgreSQL versions from 9.4 to 18 are affected, with a patch available in versions 18.6, 17.11, 16.15, 15.19, and 14.24. Organizations are advised to update their PostgreSQL instances and audit their Replication accounts.

WhatsApp rolls out emergency fix for locked Android photo access bug

WhatsApp is rolling out a fix for a privacy vulnerability affecting Android users that could allow individuals with physical access to a locked device to view the owner's photos during a video call. The issue was identified by security researcher Jose Rodriguez, who demonstrated that an incoming WhatsApp video call could provide access from the lock-screen to the device's photo gallery without unlocking the phone. WhatsApp confirmed the implementation of a fix and noted that the issue is limited to situations where someone has physical access to the device. Rodriguez reported the vulnerability to both Meta and Google, receiving limited responses. Users are advised to update WhatsApp and adjust app permissions to enhance privacy.

Decade-old PostgreSQL flaw turns backup account into a backdoor

The vulnerability CVE-2026-6471 affects PostgreSQL installations on Windows, Linux, and macOS, impacting versions since 9.4 released in 2014. All supported releases have been patched, including versions 18.6, 17.11, 16.15, 15.19, and 14.24, updated on August 13. The vulnerability arises from PostgreSQL's management of output plugins for logical replication, which are dynamically loaded compiled code, leading to insufficient existing security measures.

Bitdefender vs Norton 2026: Which Antivirus Wins?

Norton and Bitdefender both have a malware detection rate of 99.8%. Norton excels in phishing protection, blocking 95% of phishing attempts compared to Bitdefender's 89%. In terms of system impact, Bitdefender uses 11% CPU and 183 MB RAM during scans, while Norton uses 23% CPU and 384 MB RAM. Norton offers features such as cloud backup, parental controls, and unlimited VPN, whereas Bitdefender lacks cloud backup and has a limited VPN. Pricing for both is competitive, but Bitdefender generally has cheaper renewal costs. Norton provides faster customer support response times. In a comparison of nine categories, Norton won five and Bitdefender won three. For users needing backup and parental controls, Norton is preferred; for those with older laptops, Bitdefender is recommended.

Avast Antivirus Zero-Day PoC Lets Attackers Dump SAM Database and Gain SYSTEM Shell

A public proof-of-concept (PoC) repository has revealed a local privilege escalation zero-day vulnerability in GenDigital's Avast Antivirus, allowing attackers with local execution access to extract the Windows Security Account Manager (SAM) database and execute a shell with NT AUTHORITYSYSTEM privileges. The flaw is located in the Avast Sandbox component and could enable a complete local takeover of the system. The PoC is compatible with any version of Avast Antivirus and has been tested on fully patched versions of Avast and Windows 11 25H2. The repository does not provide a formal release, CVE identifier, or patch details. The vulnerability may also affect other GenDigital products like AVG and Norton. Security teams are advised to monitor for suspicious activities related to Avast services and restrict local administrator access. Organizations should inventory their deployed versions and apply vendor-provided updates as they become available.

A multi-month delay for Deus Ex turned into a huge payoff for one of its best characters, says designer Harvey Smith

Harvey Smith discussed the development of Deus Ex on the NoClip podcast, emphasizing the benefits of allowing extra time for game development, particularly in post-production. He noted that Ion Storm Austin received additional time, which enabled the team to refine the game and enhance the character Gunther Hermann, who initially had a limited role. Smith creatively integrated Gunther into a mission in a Paris cathedral, allowing for a more dynamic interaction and a dramatic moment where Gunther's presence added emotional weight to the gameplay. He highlighted the importance of providing game development teams with extra time to improve quality and creativity, suggesting that this approach could lead to greater success and recognition in the industry.

Prolific Microsoft 0-day hunter drops CrowdStrike Falcon exploit PoC

Nightmare Eclipse, a security researcher known for identifying vulnerabilities in Microsoft products, has shifted focus to other vendors, revealing a zero-day vulnerability called FalconFlank that targets CrowdStrike’s Falcon endpoint security platform. FalconFlank is a privilege escalation vulnerability that exploits the Microsoft Office malicious macros remediation feature within CrowdStrike Falcon. CrowdStrike is investigating the claims and advises customers to disable the Microsoft Office File Suspicious Macro Removal Windows policy setting while assuring them of continued protection through Cloud Anti-malware settings. The exploit works on fully updated Windows 11 25H2 and Windows Server 2025 systems running CrowdStrike Falcon with Optimal Protection enabled. Nightmare Eclipse has also discovered other vulnerabilities, including HardBreacher affecting Kaspersky’s endpoint antivirus and PrettyPrague in Gen Digital’s Avast antivirus, which allows attackers to dump the SAM database. Gen Digital is developing a patch for the Avast vulnerability, while Kaspersky has not commented. Additionally, Nightmare disclosed a memory corruption zero-day vulnerability in Nvidia, named GreenSection, which causes system crashes.

Microsoft is auto-enabling Memory Integrity on Windows 11 PCs from October. Why you shouldn’t turn it off

Starting in October 2026, Microsoft will automatically activate memory integrity for eligible Windows 11 devices through the Patch Tuesday update on October 13. Memory integrity, or Hypervisor-protected Code Integrity (HVCI), protects the core of Windows by ensuring that kernel-mode drivers are verified before execution, preventing malware from exploiting vulnerable drivers. Eligible devices must have an Intel 8th-generation processor or newer, AMD Zen 2 or newer, Qualcomm Snapdragon 8180 or newer, at least 8GB of RAM, a 64GB SSD, virtualization enabled in firmware, and compatible drivers. Secured-core PCs already have this feature enabled. Windows will assess device readiness before activation and will respect user settings if memory integrity has been intentionally disabled. Users can check memory integrity status in Windows Security under Device security. Incompatible drivers may cause issues, and conflicts will be logged in the Event Viewer. Microsoft is pushing this update due to increased security threats and aims to protect users who have upgraded their systems without performing clean installs. If issues arise with memory integrity enabled, users can identify problematic drivers in the CodeIntegrity event log.

Why does Windows constantly need to update?

Windows updates are released frequently to enhance performance, improve compatibility, fix bugs, and distribute critical security patches. Microsoft issues security updates every second Tuesday of the month, known as Patch Tuesday, which are cumulative, meaning the latest updates include all previous fixes. The Cybersecurity and Infrastructure Security Agency (CISA) issues warnings about vulnerabilities, and Microsoft maintains a security portal for documentation of these issues. Users on unsupported versions, like Windows 10 without Extended Security Updates (ESU), are at increased risk. In addition to security updates, Windows receives an annual feature update and occasional optional non-security updates that introduce new features and enhancements. An example is the Windows 11 February 2026 preview update, which added new features and improvements.
