On May 8, 2026 security researcher dwisiswant0 released a GitHub repository containing proof‑of‑concept exploits for twelve newly fixed CVEs affecting all supported Next.js and React versions, including three high‑severity SSRF, authentication‑bypass, and DoS flaws that threaten most self‑hosted deployments.
The article walks through setting up a Windows 2012 IIS environment, reverse‑engineering the product’s 3DES license check, analyzing web.config permissions, and uncovering multiple vulnerabilities—including SSRF, several SQL injections, and arbitrary file‑upload flaws—culminating in a full bypass of the EIS system’s authentication.
This article explains why the HTTP Host header is unsafe, demonstrates how attackers can hijack password‑reset links or launch SSRF by forging it, and provides three practical Nginx configuration methods to strictly validate Host values and block malicious requests.
This article demonstrates how a NextJS SSRF vulnerability (CVE‑2024‑34351) can be exploited by abusing the HTTP Host header, walks through the underlying code, reproduces the attack to retrieve a protected flag file, and discusses mitigation strategies for developers.
Label Studio versions prior to 1.6.0 contain an SSRF flaw that allows authenticated users to access arbitrary files on the server via the data import module, with self‑registration enabled by default, and a proof‑of‑concept exploit is publicly available.
This article explains the purpose of the HTTP Host header, how Host header attacks arise when the header is trusted or altered, demonstrates exploitation techniques such as modifying, duplicating, or injecting alternative header fields, and provides mitigation strategies to protect web applications.
This article explains the purpose of the HTTP Host header, how Host header attacks work, methods to discover and exploit them—including password‑reset poisoning, cache poisoning, access‑control bypass, and SSRF—and provides practical mitigation techniques for developers and security teams.
The article details a step‑by‑step penetration test of a seemingly empty financial web application, describing how hidden JavaScript files and a discovered /xxxapi/file/pdf/view endpoint were leveraged to craft an SSRF payload that accessed internal services such as Elasticsearch, illustrating practical web security exploitation techniques.
This article explains how misconfigured HTTP Host headers can be abused for attacks such as cache poisoning, SSRF, password‑reset poisoning and other server‑side exploits, and provides practical detection methods and defensive recommendations for developers and security engineers.
This article explains what server‑side request forgery (SSRF) is, describes its impact, common attack vectors such as targeting the server itself or internal services, outlines bypass techniques for blacklist and whitelist filters, and discusses blind SSRF detection using out‑of‑band methods.
This article provides a comprehensive overview of common MySQL attack techniques—including client‑side arbitrary file reads, SSRF‑based data extraction, server‑side file read/write, remote code execution vulnerabilities (CVE‑2016‑6662), and authentication bypass (CVE‑2012‑2122)—and supplies practical command examples and mitigation insights.
This article provides a detailed analysis of the recent Fastjson deserialization vulnerability, explaining how the autoType bypass can be exploited to achieve arbitrary file reads, SSRF, and other attacks by leveraging gadget classes such as AutoCloseable, and walks through the debugging process and code paths involved.
This article explains the mechanics of Cross‑Site Request Forgery (CSRF) attacks—including a step‑by‑step example of password‑change exploitation—lists the four essential conditions for a successful CSRF, introduces the related Server‑Side Request Forgery (SSRF) threat, and provides practical mitigation strategies for both vulnerabilities.
This article explains how attackers can combine SSRF vulnerabilities with unauthorized Redis access and unsafe serialization in Celery to infiltrate internal networks, illustrating the attack flow, exploitation techniques, and mitigation considerations for operations and security teams.
