Insufficient validation of untrusted input in WebML in Google Chrome on Windows prior to 147.0.7727.55 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Memory disclosure in Google Chrome on Windows prior to version 147.0.7727.55 allows remote attackers to extract sensitive information from process memory by delivering a crafted HTML page through WebML parsing. The vulnerability stems from insufficient input validation in the WebML component and requires user interaction (visiting a malicious page), making it a moderate-risk information disclosure affecting a ubiquitous browser platform.
Technical ContextAI
WebML (Web Machine Learning) is a Chrome component that processes machine learning models embedded in web pages. The vulnerability exists in the input validation logic of WebML's HTML parsing mechanism (CWE-20: Improper Input Validation). When WebML processes untrusted HTML content without sufficient validation, an attacker can craft specific HTML structures that cause the parser to read adjacent process memory regions and leak their contents back to the attacker's script context. This is a classic memory safety issue where bounds checking or type validation is insufficient, allowing out-of-bounds memory access during parsing or model interpretation.
RemediationAI
Update Google Chrome to version 147.0.7727.55 or later, which includes the WebML input validation fix. On Windows systems, Chrome typically auto-updates, but users can manually check for updates via Chrome menu > About Google Chrome. System administrators can enforce updates through Chrome enterprise policies. No interim workarounds are applicable; patching is the only remediation. Refer to https://chromereleases.googleblog.com/2026/04/stable-channel-update-for-desktop.html and https://issues.chromium.org/issues/485203823 for detailed remediation guidance.
