A critical security vulnerability, SVD-2026-0603 (CVE-2026-20253), has been identified in Splunk Enterprise versions 10.0.0 through 10.0.6 and 10.2.0 through 10.2.3. This flaw allows unauthenticated, remote attackers to create or truncate arbitrary files on the host system by exploiting the PostgreSQL Sidecar Service endpoints. The vulnerability is actively exploited, with public proof-of-concept code available, and has been added to the CISA Known Exploited Vulnerabilities (KEV) list. Successful exploitation can lead to full remote code execution (RCE) as the Splunk user. The vulnerability arises from inadequate authentication controls on the PostgreSQL Sidecar Service endpoints, specifically /v1/postgres/recovery/backup and /v1/postgres/recovery/restore, which are accessible without authentication. It is classified under CWE-306: Missing Authentication for Critical Function and has a CVSS v3.1 base score of 9.8 (Critical). Attackers can exploit the vulnerability by sending crafted HTTP POST requests to the exposed endpoints, allowing them to create or truncate files and potentially execute malicious scripts. Indicators of compromise include unexpected files in directories such as /tmp/ or /opt/splunk/var/run/supervisor/pkg-run/, modified Splunk Python scripts, and unusual outbound connections from Splunk to unknown PostgreSQL servers. The vulnerability aligns with several MITRE ATT&CK techniques, including T1190 (Exploit Public-Facing Application) and T1059 (Command and Scripting Interpreter). Active exploitation of CVE-2026-20253 has been confirmed, and it is likely that both opportunistic cybercriminals and sophisticated threat actors will use this exploit. The affected versions of Splunk Enterprise are 10.2.0 through 10.2.3 and 10.0.0 through 10.0.6, with the issue resolved in versions 10.2.4 and 10.0.7. Organizations are advised to upgrade to fixed versions or disable the PostgreSQL Sidecar Service as a mitigation strategy.

Apple has removed the Russian messaging application Max from its App Store, allowing existing users to access the service but preventing new downloads and updates. This decision was made to comply with sanctions requirements, although specific sanctions were not disclosed. Max, developed by VK, has been promoted by Russian authorities and is pre-installed on devices sold in Russia, but is not accessible in the European Union. The CEO of VK, Vladimir Kiriyenko, has faced sanctions from the U.S., U.K., and EU since 2022.

A critical vulnerability, CVE-2024-55638, has been identified in Drupal Core, affecting installations using PostgreSQL as their backend database. This vulnerability involves PHP Object Injection, which can lead to full Remote Code Execution (RCE) when combined with another deserialization flaw. It cannot be exploited independently but increases the risk for Drupal installations that use third-party modules or custom code that improperly employs the unserialize() function. The affected versions include Drupal Core 7.x prior to 7.102, 8.0.0 and above prior to 10.2.11, and 10.3.0 prior to 10.3.9, with patched versions being 7.102, 10.2.11, and 10.3.9. The vulnerability is particularly relevant for sites using PostgreSQL, and organizations are urged to upgrade to the patched versions and audit their code for unsafe unserialize() usage. Currently, there are no confirmed reports of exploitation in the wild, but the risk remains high due to insecure deserialization bugs in third-party modules. The EPSS score for this vulnerability is 9.93%, indicating a significant likelihood of exploitation in the near future.

In April 2026, two zero-day vulnerabilities, RedSun and UnDefend, were discovered in Microsoft Defender, affecting Windows 10, Windows 11, and Windows Server platforms. These vulnerabilities allow attackers to escalate privileges to SYSTEM and bypass Defender’s protections. RedSun exploits a flaw in Defender's remediation process, enabling low-privileged users to overwrite critical system files. UnDefend allows attackers to disrupt Defender’s updates, keeping it outdated and ineffective. Both vulnerabilities are actively being exploited, with attackers leveraging them to gain persistent access and deploy ransomware. The primary targets are organizations using Windows systems with Defender enabled, particularly in sectors like finance, healthcare, and government. Mitigation strategies include applying updates for related vulnerabilities, monitoring for suspicious activities, and implementing additional security measures.

Elon Musk's XChat will launch on the App Store on April 17 as a standalone encrypted messaging application focused on privacy, featuring end-to-end encryption, no advertisements, and a no-tracking policy. Initially part of the X platform, XChat was developed to compete with messaging services like WhatsApp, Telegram, and Signal. The app allows global communication using X accounts without requiring phone numbers, offering cross-platform capabilities unlike iMessage. XChat utilizes a Rust-based architecture with advanced security features and plans to incorporate peer-to-peer transfers and cryptocurrency payments with X Money in 2026, potentially disrupting traditional payment systems. Additionally, it may leverage Grok AI to provide users with various lifestyle services, posing challenges to Google's advertising and search traffic.
