3. Inside PostHog: SSRF, ClickHouse SQL Escape and Default Postgres Creds to RCE
Total comment counts : 2
Summary
During a hands-on 24-hour vendor review of PostHog, the team evaluated its self-hosted analytics and architecture. They praised its open-source, plugin-friendly design with Rust workers and Celery-like components, and noted thousands of integrations. In security terms, they identified SSRF vulnerabilities (CVE-2024-9710, CVE-2025-1522, CVE-2025-1521). The critical flaw: webhook URL validation occurs only on the frontend; a backend save endpoint accepts localhost/internal URLs, enabling persistent SSRF and a potential RCE chain through webhook delivery.

6. I got hacked: My Hetzner server started mining Monero
Total comment counts : 5
Summary
Jake Saunders recounts a Hetzner abuse alert after his server was used to mine Monero. He found about 20 containers via Coolify, with xmrig processes running as UID 1001 in the Umami analytics container. Umami is built with Next.js, and CVE-2025-66478 enabled remote code execution that could reach the host, but container isolation remained intact and the malware stayed inside the container. The author uses custom Dockerfiles and avoids root, preventing host compromise; he deleted the affected container rather than rebuilding the server. Lesson: “I don’t use Next.js” doesn’t mean dependencies don’t.
Overall Comments Summary
- Main point: The core topic is whether running a Docker container as root can lead to host compromise and how Docker’s isolation affects visibility of container processes and potential host artifacts.
- Concern: The main worry is a possible container breakout that could compromise the host, compounded by confusion and misinformation about vulnerability details.
- Perspectives: Viewpoints range from warning of root-in-container risk to skepticism and calls for testing, noting host-process visibility and criticizing the article as misinformation, with casual references to real-world targets like Next.js admin sites.

8. AWS CEO says replacing junior devs with AI is ‘one of the dumbest ideas’
Total comment counts : 55
Summary
Amazon Web Services CEO Matt Garman warns against cutting junior developers for AI cost savings, outlining three reasons. First, juniors are often more adept with AI tools—about 55% of early-career developers use AI daily—making them efficient. Second, they are cheaper, but savings are limited and layoffs can backfire. Third, fresh talent sustains a skills pipeline as demand for tech grows (Deloitte notes fast tech workforce expansion). He foresees AI transforming work and boosting productivity, but long-term AI should create more jobs than it removes, with CS fundamentals still crucial.
Overall Comments Summary
- Main point: The discussion focuses on whether AI should replace or augment junior engineers and what that implies for learning, ramp time, and future talent pipelines.
- Concern: The main worry is that AI-driven replacement or heavy reliance could undercut the talent pipeline, deskill workers, and erode organizational memory and culture.
- Perspectives: Views range from AI accelerating juniors’ ramp and freeing them from boring boilerplate to help them learn system-level integration, to concerns that it will deskill workers, hollow out the talent pipeline, and strip organizational memory, with some advocating pairing juniors with seniors to leverage AI effectively.
- Overall sentiment: Mixed
