The PostgreSQL Global Development Group has released security and maintenance updates for versions 17.6, 16.10, 15.14, 14.19, 13.22, and the third beta of PostgreSQL 18. The updates address three critical vulnerabilities: 1. CVE-2025-8714 (CVSS 8.8) - Allows code injection during dump restoration via pg_dump operations. 2. CVE-2025-8715 (CVSS 8.8) - Enables SQL injection through newline injection in object names during pg_dump. 3. CVE-2025-8713 (CVSS 3.1) - Exposes optimizer statistics data. The update also improves BRIN index performance, logical replication, and resolves WAL segment removal issues. PostgreSQL 13 will reach end-of-life on November 13, 2025. The third beta of PostgreSQL 18 is in development, with general availability expected in September-October 2025. Administrators should perform reindexing after the upgrade if using specific BRIN indexes.

The PostgreSQL Global Development Group released emergency security updates on August 14, 2025, to address three critical vulnerabilities affecting PostgreSQL versions 13 through 17. The vulnerabilities include: 1. CVE-2025-8714: Allows arbitrary OS code execution via pg_dump meta-commands, with a CVSS score of 8.8. 2. CVE-2025-8715: Facilitates code/SQL injection through improper newline handling in object names, also with a CVSS score of 8.8. 3. CVE-2025-8713: Exposes sensitive data via optimizer statistics, with a CVSS score of 3.1. Organizations are advised to upgrade to PostgreSQL versions 17.6, 16.10, 15.14, 14.19, or 13.22 immediately. Cloud providers have begun emergency fleet updates, and development teams should audit their CI/CD pipelines for pg_dump usage. The vulnerabilities were disclosed responsibly by several individuals, and PostgreSQL 13 will reach its end-of-life on November 13, 2025.

Wiz has transitioned its Amazon Aurora PostgreSQL database from version 14 to version 16 with near-zero downtime using Aurora Blue/Green Deployments. The upgrade process is facilitated by the DB Upgrade Pilot, which features an automated eight-step flow, including automated validation steps, enhanced synchronization monitoring, and end-to-end orchestration. This has reduced the downtime for database upgrades from one hour to 30 seconds.

Epic Games filed lawsuits against Apple and Google in 2020 for restricting users' access to Epic's offerings through third-party app stores. The Ninth Circuit ruled in favor of Epic against Google, finding antitrust violations, while Epic lost the federal antitrust case against Apple. The Department of Justice also filed a lawsuit against Apple under Section 2 of the Sherman Act for monopolization. Apple's closed system was found to be successful, while Google's open-source system faced legal challenges. The court in the Google Play case issued remedies targeting exclusivity, which could lead to better user experiences and lower prices.

PostgreSQL can serve as a powerful all-in-one database, but real-world implementations often complicate its effectiveness due to complex corporate infrastructures. Accessing a production database may involve numerous network hops, firewalls, and antivirus software that can slow down performance. The lack of administrative privileges can hinder the use of extensions. Developers often turn to Kubernetes for more freedom, but this can introduce new challenges, such as unpredictable resource allocations and performance inconsistencies. Row-Level Security (RLS) can lead to performance overhead and complicate debugging. Centralizing business logic in stored procedures can enhance performance but complicates version control and tracking changes. In large organizations, policies governing technology use often create bottlenecks. PostgreSQL may not be optimal for portable setups (SQLite), simple caching (Redis), or specialized search functionalities (Elasticsearch, Meilisearch). It is most effective when developers have control over the environment, allowing it to handle various applications efficiently.

A wave of mobile malware is targeting Android users in India, posing as legitimate banking applications. This malware can fully compromise infected devices, stealing sensitive data, intercepting communications, and conducting unauthorized financial transactions. It typically spreads through deceptive "dropper" apps via phishing messages on platforms like WhatsApp, SMS, or email, often disguised as system updates or official banking apps. The malware requests extensive Android permissions, allowing it to read and send SMS messages and intercept two-factor authentication codes. It operates stealthily, bypassing Android’s battery optimization features, and can manipulate notification content. All captured data is transmitted to attackers, enabling potential financial fraud and identity theft. Users are advised to install apps only from trusted sources, be skeptical of unexpected installation prompts, and review permission requests carefully.
