Date Added Resource Excerpt
2026-04-22 2026CVE 2026: When Identity Breaks and Legacy Code Bites BackAuthZAnalysis of CVE-2026-24858, a critical Fortinet SSO logic flaw, and CVE-2026-24061, an argument injection in GNU InetUtils' telnetd, highlighting early 2026's vulnerability landscape dominated by legacy code exploits and advanced Agentic AI threats. The analysis details the mechanics and exploit logic for both, emphasizing the reduced exploitation windows and the need for continuous, AI-driven validation to combat automated exploitation.
2026-04-22 2026IDOR in the Wild: What CVE-2025-13526 Teaches Security EngineersIDORWriteup analyzing CVE-2025-13526, an Insecure Direct Object Reference (IDOR) in a WordPress plugin, highlights how attackers can exploit simple parameter manipulation to access unauthorized data. The article details the mechanics of IDOR, linking it to OWASP API1 (Broken Object Level Authorization) and CWE-639, and emphasizes its prevalence due to rapid development, testing biases, and scattered authorization logic, particularly in the API and AI-driven security landscape. Practical fixes involve centralizing authorization checks and verifying ownership of accessed objects.
2026-04-17 2026CVE-2026-29000: pac4j-jwt Authentication BypassJWTWriteup on CVE-2026-29000 detailing an authentication bypass in pac4j-jwt. This critical vulnerability, classified as CWE-347, allows unauthenticated remote attackers possessing the server's RSA public key to craft a JWE-wrapped PlainJWT with arbitrary claims, effectively bypassing signature verification and authenticating as any user, including administrators. Affected versions are prior to 4.5.9, 5.7.9, and 6.3.3, with proof-of-concept code publicly available. The exploit leverages a flawed trust model where token decryption is mistakenly treated as proof of identity.
2026-04-10 2026Private IP Addresses Deep Dive: Security Risks, SSRF, and ExploitationSSRFLibrary for validating IP addresses, mitigating Server-Side Request Forgery (SSRF) risks, and identifying internal network vulnerabilities. It highlights RFC 1918 private IP ranges, cloud metadata access via 169.254.169.254, and CVE-2025-8080 which bypassed the private-ip npm package. The library aids in preventing exploitation of internal services and insecure API endpoints through robust validation and network segmentation, drawing parallels to OWASP API7:2023 SSRF and advisories from GitLab.
2026-04-10 2026OpenClaw: Authorization Bypass and Privilege EscalationAuthZLibrary detailing authorization bypass and privilege escalation vulnerabilities within multi-user OpenClaw deployments, specifically addressing session context bleed. This failure mode allows standard users to execute actions with administrative privileges by exploiting weaknesses in how user identity is bound to requests, especially under asynchronous conditions. The article explains how this can lead to persistence through unauthorized job creation, impacting systems that rely on session context for RBAC, and references CWE-287 and CWE-284.
2026-04-10 2026Bug Bounty Hunter Software in 2026: What Belongs in Your StackBug BountyLibrary for composing a bug bounty hunting software stack in 2026, emphasizing the need for tools that manage traffic, map assets, generate coverage, validate signals, and create evidence. It highlights that modern bug bounties require a layered approach rather than a single solution, with specific mentions of Burp Suite for traffic control, ProjectDiscovery tools for recon, OWASP Amass for asset mapping, and Nuclei for template-based coverage, acknowledging shifts towards AI vulnerabilities and broken access control.
2026-04-10 2026Burp AI in 2026: Real Workflow ChangesBurpLibrary integrating AI into Burp Suite Professional (v2025.2+) for enhanced web security testing. Features include Burp AI in Repeater for auditable HTTP message analysis, Explainer for quick understanding of unfamiliar artifacts, and Explore Issue for automated follow-up on Burp Scanner findings. Usage is consumption-based via AI credits assigned per user, requiring careful management of prompts for cost-effectiveness and accurate validation of vulnerabilities.
2026-04-10 2026Agentic AI Security in Production: MCP, Memory Poisoning, Tool MisuseAITool, a comprehensive analysis of agentic AI security in production, details critical failure modes including MCP Security, Memory Poisoning, and Tool Misuse. It highlights the evolving threat landscape where agents plan and execute actions, emphasizing system design over prompt-level fixes. Specific vulnerabilities like CVE-2025-68144 in mcp-server-git and attack models such as MINJA and AgentPoison are examined, underscoring the need for robust controls across input, memory, tool execution, and identity planes to manage the expanded attack surface created by these systems.
