The vendor released 2.15.2 to enforce numeric validation of payment IDs, adopt prepared statements and strengthen input handling; administrators should update immediately.

WhatsApp Patches Zero-Click Zero-Day Exploit in iOS

🔒 WhatsApp has patched a critical zero-day (CVE-2025-55177) affecting linked-device synchronization that could allow processing of content from an arbitrary URL on a target device. The vendor says the flaw, when combined with an Apple OS-level out-of-bounds write (CVE-2025-43300), may have been exploited in a targeted, sophisticated zero-click attack. Apple patched the related OS issue on August 20. Users should apply the updated WhatsApp and WhatsApp Business iOS and Mac clients immediately.

WhatsApp Emergency Update Fixes Zero-Click iOS/macOS Bug

🔒 WhatsApp has issued emergency updates for iOS and macOS to fix CVE-2025-55177, a high-severity authorization flaw that may have been exploited alongside an Apple ImageIO zero-day (CVE-2025-43300).

Users are urged to update immediately; confirmed targets were advised to perform a full factory reset.

Microsoft Fixes Bug Causing Certificate Enrollment Errors

🔧 Microsoft has addressed a known issue that produced false CertificateServicesClient (CertEnroll) error events after the July 2025 non-security preview (KB5062660) and subsequent Windows 11 24H2 updates. The events referenced the Microsoft Pluton Cryptographic Provider not being loaded but were benign and caused by a partially integrated feature still under development. The fix is rolling out automatically and requires no user action.

Sitecore Vulnerabilities Enable Cache Poisoning to RCE

🔒 Three vulnerabilities affecting the Sitecore Experience Platform can be chained to escalate from HTML cache poisoning to remote code execution. Researchers describe a pre-auth HTML cache reflection (CVE-2025-53693) combined with an insecure deserialization RCE (CVE-2025-53691) and an ItemService API information-disclosure bug (CVE-2025-53694) that permits cache key enumeration and poisoned HTML injection. Sitecore issued patches in June and July 2025; administrators should apply updates, restrict ItemService exposure to trusted networks, and consider WAF rules and other mitigations to reduce the chaining risk.

WhatsApp patches iOS and macOS zero-day vulnerability

🔒 WhatsApp has patched a zero-click vulnerability (CVE-2025-55177) impacting WhatsApp for iOS prior to 2.25.21.73, WhatsApp Business for iOS v2.25.21.78, and WhatsApp for Mac v2.25.21.78. The flaw involved incomplete authorization of linked-device synchronization messages that could trigger processing of content from an arbitrary URL on a target device. WhatsApp said the bug may have been chained with an Apple OS-level zero-day (CVE-2025-43300) and exploited in targeted, sophisticated attacks. Potentially impacted users have been urged to perform a factory reset and keep their operating systems and apps up to date.

WordPress Plugin and Theme Vulnerabilities Surge in 2025

⚠️ Recent investigations show a wave of active attacks against WordPress plugins and themes, including Gravity Forms, the Alone and Motors themes, and Post SMTP. Exploits have enabled remote code execution, administrator account takeover, and mass site compromise, while the Efimer trojan has been distributed from some infected sites. Vendors have issued patches, but many sites remain unpatched—site owners should update immediately and follow hardening best practices.

Microsoft: August KB5063878 not tied to SSD failures

🔍 Microsoft says its August 2025 security update, KB5063878, is not connected to recent reports of SSD and HDD failures. After internal testing and telemetry analysis, Redmond said it could not reproduce the corruption or drive losses and found no increase in disk failures following the Windows 11 24H2 update. Microsoft is working with storage partners and controller vendors and will continue to monitor customer feedback while investigating any new reports.

CISA Adds Sangoma FreePBX CVE to Known Exploited List

⚠️ CISA added CVE-2025-57819, an authentication bypass in Sangoma FreePBX, to its Known Exploited Vulnerabilities (KEV) Catalog after evidence of active exploitation. The vulnerability is a frequent attack vector that poses significant risk to the federal enterprise. Under BOD 22-01, Federal Civilian Executive Branch agencies must remediate KEV items by required due dates. CISA urges all organizations to prioritize timely remediation.

Click Studios Patches Passwordstate Authentication Bypass

🔒 Click Studios released Passwordstate 9.9 (Build 9972) on August 28, 2025, to remediate a high-severity authentication bypass that could be triggered via a carefully crafted URL against the product's Emergency Access page. The update also introduces enhanced safeguards in the web interface and browser extension to mitigate DOM-based clickjacking attacks. The company noted that no CVE has been assigned yet and emphasized that customers should apply the update promptly. Passwordstate is used by thousands of organizations globally, increasing the urgency of patching.

Critical FreePBX Zero-Day Under Active Exploitation

🚨 The Sangoma FreePBX project has issued an advisory for an actively exploited zero-day (CVE-2025-57819) that allows unauthenticated access to the Administrator control panel, enabling arbitrary database manipulation and remote code execution. The flaw stems from insufficiently sanitized user input in the commercial endpoint module and impacts FreePBX 15, 16, and 17 prior to their listed patched releases. Administrators should apply the emergency updates immediately, restrict public ACP access, and scan for indicators of compromise.

VS Code Marketplace Flaw Lets Deleted Extensions Be Reused

🔍 Researchers at ReversingLabs found a loophole in the Visual Studio Code Marketplace that permits threat actors to republish removed extensions under the same visible names. The new malicious package, ahbanC.shiba, mirrors earlier flagged extensions and acts as a downloader for a PowerShell payload that encrypts files in a folder named "testShiba" and demands a Shiba Inu token ransom. Investigation revealed that extension uniqueness is enforced by the combination of publisher and name, not the visible name alone, enabling attackers to reuse names once an extension is removed. Organizations should audit extension IDs, enforce whitelists, and run automated supply-chain scanning to reduce exposure.

Amazon RDS Custom Adds New GDRs for SQL Server 2019/2022
