25 May 2026 The Hidden Complexity of NGINX: When DIY Configuration Costs More Than Support

The Gap Between Getting NGINX Running and Getting It Right There is a version of NGINX that most teams encounter first: the one that installs cleanly, serves a default page, and seems straightforward enough that configuring it for production feels like a natural next step. That version is real. NGINX is genuinely well-documented, widely adopted, […]

Kibana: Authorization Bypass and Unauthorized Data Modification in AI Assistant

In Kibana versions up to 8.16.2.a medium severity vulnerability CVE-2026-78581 was detected. This vulnerability allows an authenticated attacker to access or modify AI Assistant conversations they do not own, leading to unauthorized data modification and potential information disclosure. This occurs due to an Authorization Bypass Through User-Controlled Key (CWE-639) flaw. By referencing another user’s AI Assistant conversation identifier, an attacker can bypass Access Control Lists (ACLs) and interact with that conversation (CAPEC-1). However, successful exploitation requires the attacker to obtain or guess this specific, hard-to-guess identifier. To address this issue, users should upgrade Kibana to a patched version Elastic Kibana versions 8.16.3 and 8.17.2.. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-78581.

10 Aug 2026 Identifying client IPs and limiting heavy queries for Patroni PostgreSQL behind HAProxy

Problem: Production PostgreSQL clusters (PostgreSQL community edition 15.17) are running under Patroni (v3.3.2) with HAProxy (2.6.21) in front. All client connections go through HAProxy using virtual IPs and virtual ports; on the PostgreSQL side the reported client address is the HAProxy VIP rather than the originating physical client IP. The operations team needed a reliable […]

Problem: A production PostgreSQL cluster (community PostgreSQL 15.8, managed by Patroni v2.1.4) experienced an unplanned automatic switchover. Symptoms reported included an unexpected promotion of the standby after the primary stopped responding to health checks. Monitoring and OS traces showed memory usage climbing to ~95% on the primary node, PostgreSQL failing to respond to Patroni probe […]

13 Jul 2026 PostgreSQL failover: primary saturation caused promotion and WAL loss prevented automatic rejoin

Problem: A high-traffic Patroni-managed PostgreSQL cluster experienced an automatic failover: the former primary (node A) lost leadership, and a secondary (node B) was successfully promoted. However, after the failover, node A failed to automatically rejoin the cluster as a replica. The symptoms unfolded in three stages. First, direct streaming replication was immediately rejected by the […]

22 Jun 2026 Automating DR site rebuild for a large Patroni PostgreSQL cluster

Problem: A customer running Patroni-managed PostgreSQL (PostgreSQL 15.17, Patroni v3.3) had production databases ranging from >2-3 TB up to a ~52 TB physical replica. Rebuilding the empty DR site from production relied on manual pg_basebackup executions and manual post-backup recovery steps, which was too slow, operationally intensive, and prone to human error for such large volumes.
