Inappropriate implementation in SanitizerAPI in Google Chrome prior to 148.0.7778.96 allowed a remote attacker to inject arbitrary scripts or HTML (UXSS) via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Google Chrome versions prior to 148.0.7778.96 contain an XSS vulnerability in the SanitizerAPI that allows remote attackers to inject arbitrary scripts or HTML through crafted HTML pages. The vulnerability requires user interaction (visiting a malicious page) but carries medium severity due to its ability to compromise confidentiality and integrity. No public exploit code or active exploitation in CISA KEV has been identified at the time of analysis.
Technical ContextAI
The SanitizerAPI in Chromium is a security feature designed to sanitize HTML content to prevent cross-site scripting attacks. This vulnerability stems from an inappropriate implementation of the sanitization logic (CWE-79: Improper Neutralization of Input During Web Page Generation), allowing attackers to bypass the intended filtering mechanism. When a user visits a crafted HTML page, the SanitizerAPI fails to properly neutralize malicious script tags or event handlers, enabling Unrestricted XSS (UXSS) that operates in the context of the affected website or application. The CPE cpe:2.3:a:google:chrome indicates this affects the Chrome browser application across all platforms.
RemediationAI
Update Google Chrome to version 148.0.7778.96 or later. The vendor has released a patched version available through the Chrome automatic update mechanism; users should verify their installed version matches the fix release via Settings > About Chrome, which will automatically download and install the latest stable version. No known workarounds mitigate this vulnerability in vulnerable versions; patching is the primary remediation. The Chrome release notes at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop.html provide additional context and a full security update list.
