A critical, unauthenticated Remote Code Execution (RCE) vulnerability, CVE-2025-55182, has been discovered in React Server Components and Next.js with the maximum severity rating of 10.0. The article highlights that Traceable by Harness WAF provided immediate, proactive protection against this vulnerability class through multi-layered defenses like Server Side Template Injection (SSTI) and Node.js Injection attack rules, even before the CVE was officially disclosed.

Some log sources bundle multiple events into a single record before shipping them. This is common with VPC flow logs, CloudWatch exports, and certain Windows endpoint collectors. While this batching approach is efficient for transport, it creates challenges when you need to filter, search, or correlate individual events. When a log record contains an array of 47 events, your analytics tool sees one entry instead of 47 distinct records.

Ask a SaaS team how they measure cloud efficiency, and you’ll hear familiar things. Total cloud spend. Average cost per customer. Maybe a breakdown of spend by service. All useful, but rather wobbly. Now ask, “What does it cost you to serve one more customer?” That’s when the room goes quiet. And that’s often where cloud economics gets really wobbly. Because that number, your marginal cost, is what actually determines your margins. Not your total cloud bill.

Managing TLS certificates at scale is one of those operational tasks that starts simple and quickly grows into a sprawling problem. As organizations adopt microservices, multi-tenant architectures, and globally distributed load balancers, the number of domains and subdomains they support can expand dramatically. Each certificate then requires its own lifecycle management: Wildcard certificates offer a powerful solution to this growing complexity.

AI speeds delivery but expands risk. Teams need context, verification, behavior detection, and learning to stay secure by default. Software delivery has been accelerating for more than a decade, and the arrival of AI has pushed us into an entirely new velocity class. Code generation, configuration scaffolding, infrastructure suggestions, remediation hints, and deployment decisions now involve AI. It participates in every stage of the delivery pipeline. On the surface, this feels like progress.

November was another big month for Harness AI, with new capabilities that deepen our work with AWS, bring AI-native automation to the database, and keep our model stack on the cutting edge across the SDLC.
