📊 HiddenMerit Daily · Issue 27 Focus on Database Frontiers, Practical Insights for DBAs May 22, 2026 ｜ 5 Selected Global Breaking News 01｜ChromaDB Exposed to Highest Severity Vulnerability: 10 Million Downloads AI Vector Database Hides “Remote Hijacking” Risk for RAG Applications ChromaDB, an open‑source vector database widely used by application developers, has recently been disclosed to have a highest‑severity security vulnerability, numbered CVE-2026-45829. The vulnerability allows an unauthenticated attacker to execute arbitrary code on servers exposed to the internet, posing a risk of full system compromise. The vulnerability was discovered by security company HiddenLayer. The core issue lies in a logical flaw in an API endpoint marked as requiring authentication in the Python FastAPI version of the server – the system allows embedding model parameters to be set before performing authentication checks. Attackers can craft specific requests to force ChromaDB to load malicious models from the Hugging Face platform and execute them locally on the server, without authentication intercepting the request. By the time the authentication step is triggered, the malicious model has already been loaded and executed. ChromaDB’s PyPI package has nearly 14 million monthly downloads, indicating its high popularity among the global developer community. CVE-2026-45829 was introduced […]

📊 HiddenMerit Daily · Issue 26 Focus on Database Frontiers, Practical Insights for DBAs May 21, 2026 ｜ 5 Selected Global Breaking News 01｜Google Urges PostgreSQL Developers to Leverage AI Coding at Scale, Alibaba Cloud Leads Domestic Open‑Source Contributions On May 20, Google published a strong call for PostgreSQL developers to “massively” adopt AI coding tools for code generation, testing, and optimisation during development. This statement comes as Google increases its contributions to open‑source projects like PostgreSQL – earlier this year, Google contributed a series of new PostgreSQL code, including parallel hash join optimisations and new performance monitoring infrastructure. Google’s core argument is that human‑AI collaboration can dramatically reduce monotonous, repetitive tasks in database kernel development, allowing developers to focus on more complex system logic innovation. Since the beginning of this year, the penetration of AI‑assisted coding tools in database kernel development has significantly increased. At the same time, Alibaba Cloud has recently completed large‑scale kernel‑level contributions from PolarDB to the PostgreSQL community, covering key modules such as executor optimisation and lock manager enhancements, demonstrating that the technology backflow path of domestic databases into the open‑source ecosystem is becoming increasingly mature and systematic. · DBA Perspective: The examples from Google […]

The procurement method was competitive negotiation. This is the second time in a short period that PICC Technology has introduced domestic databases at scale. In the previous 2025‑2026 Database Related Basic Software Maintenance Service Procurement (Package 1), it had already procured original factory services from three domestic databases. As a leading institution in the insurance industry, PICC Technology’s continuous inclusion of domestic databases in its original factory standard service scope indicates that the insurance industry’s Xinchuang transformation has completed multi‑vendor adaptation and technical reserves, and the procurement model has formally shifted from “single‑point pilot” to “regular expansion procurement.” – **DBA Perspective**: A major insurer procuring three domestic databases in bulk sends a **clear […]

By choosing Hong Kong as a strategic hub, Dameng not only takes a key step in deepening its international presence but also builds a bridge for China’s independent database technology to engage with the world, marking a transition from “technology breakthrough” to “going global.” DM9 introduces over 450 new features and enhancements, covering performance optimisation, high availability, compatibility, security, and multi‑model support. The DAMENG PAI all‑in‑one machine follows a “software‑hardware synergy” concept, delivering extreme performance tuning and intelligent O&M capabilities for high‑grade industry core systems. Earlier in late April, Dameng had already released four new products at the 2026 China Database Technology and Industry Conference: DM9, GDMBASE V4.0, DAMENG PAI V2.0 all‑in‑one, and Qiyun Database V4.0, covering centralised, distributed, cloud‑native, and graph database scenarios. By mid‑May, Dameng brought DM9 and DAMENG PAI […]

The entire amount will be invested in two cutting‑edge R&D projects: RMB 489 million for a next‑generation high‑performance hybrid transaction/analytical database (HTAP) project, and RMB 213 million for a multi‑modal time‑series database project. Vastbase believes that the traditional “OLTP database + OLAP data warehouse” separated architecture can no longer meet the real‑time, integrated, and high‑concurrency requirements of core scenarios such as finance, retail, telecommunications, and manufacturing. The drawbacks – high O&M costs, data synchronization latency, and difficulty ensuring consistency – have become prominent. The HTAP architecture, with its two core technical advantages of row‑column hybrid storage and unified transaction/analytics processing, can deliver both high‑concurrency transaction performance and batch analytical efficiency. The multi‑modal time‑series database project targets core needs in emerging scenarios such as industrial IoT and energy dispatch, aiming to solve the heavy reliance on foreign technology and insufficient multi‑modal […]

This month, the top ten positions saw zero changes, but key metrics continued to rise – OceanBase maintained the top spot with 830.74 points. The moats of leading vendors in critical industry applications are becoming more solid, and domestic database competition has officially moved from the “land‑grab phase” into the second half – “deep cultivation of existing markets.” In the AI direction, leading products are moving from “external adaptation” to “kernel co‑existence.” OceanBase released the seekdb M0 plugin, creating an “external memory hub” for the AI agent framework OpenClaw through hybrid retrieval and zero‑overhead compression. This completely solves the pain point of large models “losing memory on power‑off,” giving AI a production‑grade persistent memory layer. Dameng DM9, with its “centralised + distributed + TP + AP + AI” five‑in‑one architecture, integrates “design agents” and “operations agents,” moving databases from “passive response” to “self‑design and self‑healing.” Kingbase (Kingware) remains firmly in third place, […]

Upcoming regions include Canada (Toronto) and Australia (Sydney). Oracle Database@AWS runs on OCI hardware inside AWS data centres, offering Oracle Exadata Dedicated Infrastructure database service and Oracle Autonomous Database service. The service is deeply integrated with Amazon EC2, EKS, and ECS, supporting core AI features of Oracle 23ai such as AI vector search, embedded machine learning, natural language query (NLQ), and automatic index optimisation, enabling unified governance of structured and unstructured data. · DBA Perspective: The deep collaboration between Oracle and AWS – long‑time rivals – sends a clear signal: “Multi‑cloud is no longer an option, it is a necessity.” In the past, DBAs were forced to choose sides between cloud vendors and Oracle; now they can deploy Oracle directly from the AWS console, with low‑latency direct connectivity over […]
