WatchTowr Labs detailed the exploitation of CVE-2026-20253, a critical pre-authentication Remote Code Execution (RCE) vulnerability in Splunk Enterprise. By abusing unauthenticated PostgreSQL Sidecar Service endpoints and injecting connection string parameters, attackers can force the server to connect to an external database, write malicious files to the filesystem, and overwrite legitimate scripts to achieve arbitrary code execution.

Why Use App-Level Auth When Every Database Has Auth? (Splunk Enterprise CVE-2026-20253 Pre-Auth RCE) From SQLi to RCE – Exploiting LangGraph’s Checkpointer Check Point Research discovered critical vulnerabilities in LangGraph's SQLite and Redis checkpointers that allow attackers to chain SQL injection with unsafe msgpack deserialization to achieve Remote Code Execution (RCE). The flaws occur when user-controlled input is passed to the getstatehistory() filter, enabling attackers to inject malicious serialized payloads that execute arbitrary OS commands upon deserialization.
25th May – Threat Intelligence Report This threat intelligence report highlights multiple high-profile breaches, including 7-Eleven and GitHub, alongside the active exploitation of vulnerabilities in Windows Defender, Trend Micro, and Drupal. It also details emerging threats such as the Kali365 phishing kit, AI-driven prompt injection attacks, the Nimbus Manticore IRGC-linked campaign deploying the MiniFast backdoor, and a supply chain attack on Laravel Lang packages.
CVE-2026-9082: Mitigating a Critical SQL Injection Vulnerability in Drupal A critical SQL injection vulnerability (CVE-2026-9082) in Drupal core allows unauthenticated attackers to exfiltrate sensitive data or bypass authentication. The flaw specifically affects Drupal environments utilizing a PostgreSQL database backend alongside the JSON:API, Views, or Entity autocomplete modules, stemming from the improper sanitization of PHP array keys before they reach the database abstraction layer.
Feeding Frenzy: RCE on Azure Cosmos for PostgreSQL Varonis Threat Labs identified a Remote Code Execution (RCE) vulnerability in Azure Cosmos for PostgreSQL caused by improper input validation of the loglineprefix parameter within the Azure management API. By utilizing form feed and newline characters, attackers could bypass single-quote restrictions to inject arbitrary PostgreSQL configurations, such as archive_command, ultimately leading to arbitrary OS command execution on the underlying managed database node.
