React2Shell: The Frontend Vulnerability That Unlocks Your Internal APIs

The cybersecurity world is currently buzzing about React2Shell (CVE-2025-55182), a critical remote code execution (RCE) vulnerability affecting React and Next.js. The scale of the threat is massive: researchers have already identified over 77,000 vulnerable IP addresses exposed to the internet, and confirmed that state-sponsored actors and opportunistic crypto miners have already breached at least 30 organizations. But if you look closely, this isn't really a story about React.

CVE-2025-59718 and CVE-2025-59719: FortiCloud SSO Login Authentication Bypass

On December 9, 2025, Fortinet released an advisory detailing two critical authentication bypass vulnerabilities affecting FortiOS, FortiWeb, FortiProxy, and FortiSwitchManager. Designated CVE-2025-59718 and CVE-2025-59719, these vulnerabilities allow an unauthenticated threat actor to bypass FortiCloud SSO login authentication via a crafted SAML message if the feature is enabled on the device. Fortinet states that FortiCloud SSO login is disabled by default in factory settings.

OWASP Top 10 for Agentic Applications (2026): What Developers and Security Teams Need to Know

Agentic AI is moving into production in CI/CD pipelines, internal copilots, customer support workflows, and infrastructure automation. These systems no longer just call a model. They plan, decide, delegate, and take actions on behalf of users and other systems. This creates new attack surfaces that do not map cleanly to traditional application security or even the OWASP Top 10 2025.

CVE-2025-66516: Critical XXE Vulnerability Exposes Apache Tika Deployments

A critical XXE vulnerability, CVE-2025-66516, has been discovered in Apache Tika, putting any workflow that processes PDFs at serious risk. A malicious PDF can trigger the exploit through any Tika workflow, silently giving attackers access to sensitive files, internal URLs, cloud metadata, and your internal network. AppTrana blocks these malicious PDFs at the edge, keeping your data and internal systems secure.

What are you doing to stay safe from supply chain attacks?

Automatic updates were supposed to make us safer. Instead, they’ve become one of the easiest entry points for supply-chain attacks. When a public repository is compromised, an attacker uploads a malicious version and waits, for 30 minutes to a few hours, before the community detects and removes it. During that window, automated tools like Dependabot can pull that version straight into production. That small window of time is enough to compromise thousands of systems.

The Real Remediation Bottleneck

Most teams think vulnerability scanning equals progress. But scanning without effective remediation is just expensive noise. Two things block real fixes: Meanwhile, our own research shows as much as 30% of vulnerabilities in transitive dependencies remain unresolved, simply because upgrades break production. That means most organizations aren’t “secure”. They’re sitting on unfixed issues their scanners excluded.

Cato CTRL Threat Brief: "React2Shell" Vulnerability Targeting React Server Components

On Wednesday, December 3, a critical remote code execution (RCE) vulnerability in React Server Components (RSC), dubbed React2Shell (CVE-2025-55182), was disclosed. The CVE was discovered by security researcher Lachlan Davidson. It quickly gained traction with multiple third-party proof of concepts (PoCs) being published of varying quality and credibility.

CVE-2025-55182: The critical React RCE and the hidden risk in your supply chain

‍On December 3rd, the React team disclosed a critical security flaw in React Server Components known as CVE-2025-55182. With a CVSS score of 10.0, this issue is extremely severe. React and Next.js are the backbone of the modern web. Consequently, this vulnerability likely sits deep within your third-party vendor ecosystem in addition to your own codebase.
