CVE Summary Severity CVSS EPSS Priority Signals
CVE-2025-55182 React Server Components in React 19.x contain a critical pre-authentication remote code execution vulnerability (CVE-2025-55182, CVSS 10.0) through unsafe deserialization of HTTP request payloads. With EPSS 71.1% and KEV listing, this vulnerability affects any application using React Server Components with react-server-dom-webpack, react-server-dom-turbopack, or react-server-dom-parcel — enabling complete server compromise through a single HTTP request. CRITICAL 10.0 71.1% 216
KEV PoC
CVE-2026-3910 Chrome's V8 JavaScript engine contains an inappropriate implementation (CVE-2026-3910, CVSS 8.8) that allows remote attackers to execute arbitrary code within the browser sandbox via crafted HTML pages. KEV-listed with public PoC, this V8 vulnerability affects all Chromium-based browsers and enables drive-by exploitation through any web page containing malicious JavaScript. HIGH 8.8 0.1% 119
KEV PoC
CVE-2026-11645 Remote code execution in Google Chrome's V8 JavaScript engine prior to 149.0.7827.103 allows a remote attacker to execute arbitrary code inside the renderer sandbox by enticing a victim to visit a crafted HTML page. The flaw is an out-of-bounds read and write (CWE-125) rated High severity by Chromium with a CVSS 8.8, and no public exploit identified at time of analysis, though V8 memory-corruption issues historically attract exploit development. HIGH 8.8 0.1% 119
KEV PoC
CVE-2026-3909 Google Chrome's Skia graphics library contains an out-of-bounds write (CVE-2026-3909, CVSS 8.8) enabling remote attackers to perform memory corruption through crafted HTML pages. KEV-listed with public PoC and patches available, this vulnerability in the core graphics rendering engine affects all Chromium-based browsers. HIGH 8.8 0.1% 119
KEV PoC
CVE-2026-2441 Google Chrome's CSS engine contains a use-after-free vulnerability (CVE-2026-2441, CVSS 8.8) that allows remote attackers to execute arbitrary code within the browser sandbox through crafted HTML pages. KEV-listed with public PoC, this vulnerability enables drive-by exploitation when users visit malicious or compromised websites. HIGH 8.8 0.1% 114
KEV PoC
CVE-2023-43000 A use-after-free issue was addressed with improved memory management. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Actively exploited in the wild (cisa kev) and public exploit code available. HIGH 8.8 0.1% 114
KEV PoC
CVE-2025-43529 WebKit arbitrary code execution via use-after-free memory corruption affects Safari 26.2, iOS/iPadOS 18.7.3 through 26.2, macOS Tahoe 26.2, tvOS 26.2, visionOS 26.2, and watchOS 26.2, allowing remote attackers to execute arbitrary code by convincing users to visit malicious websites. This vulnerability is confirmed actively exploited (CISA KEV) in extremely sophisticated targeted attacks against specific individuals on iOS versions prior to iOS 26, per Apple's security bulletin. EPSS score of 0.12% (32nd percentile) significantly understates real-world risk given confirmed exploitation. Related vulnerability CVE-2025-14174 was issued for the same exploitation campaign, suggesting a complex attack chain targeting Apple ecosystem users. HIGH 8.8 0.1% 94
