GraphQL APIs offer flexibility but expose risks like access control flaws, DoS attacks, and injections. In my latest in-depth exploration, uncover schema introspection for recon, BOLA exploits with cURL examples and Burp workflows, SQL/NoSQL injections, and command injection like Chaos Mesh’s RCE issues. Test for DoS via complex queries (with caution—often out of scope). Tools such as GraphQL Voyager, InQL, and GraphQLMap streamline testing. Defenses include disabling introspection, granular auth, and query limits. Vital for pentesters in modern stacks.

Mastering XSS Categories: Precise Detection and PoC Crafting in Modern JS Apps
In my latest deep-dive, I explore the evolving landscape of XSS vulnerabilities in 2025, emphasizing precise categories like Reflected, Stored, DOM-based, and hybrids such as Reflected DOM-XSS and Stored DOM-XSS. Drawing from recent CVEs in Adobe Experience Manager and WordPress plugins, I outline source-sink tracing workflows using tools like Burp’s DOM Invader and browser devtools to detect flaws that server-side scanners miss. Key insights include tailoring PoCs to sinks, for example, using the onerror event handler with an img tag for innerHTML while avoiding non-executing script tags, and testing fragments, client storage, and postMessage channels in SPAs. Recommendations focus on sink-aware payloads, hybrid path coverage, and defenses like Trusted Types and context-appropriate encoding to build reproducible exploits and strong mitigations.
