CVE-2026-10017
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOut of bounds read in Headless in Google Chrome prior to 148.0.7778.216 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if Google Chrome is installedLocate the Chrome executable on the system. On Windows, check C:\Program Files\Google\Chrome\Application\chrome.exe. On macOS, check /Applications/Google Chrome.app. On Linux, check /usr/bin/google-chrome or /opt/google/chrome/google-chrome.Affected if Google Chrome is not installed on the system.
-
Determine the installed Chrome versionRun the command 'google-chrome --version' on Linux/macOS, or right-click the Chrome executable, select Properties, and view the Details tab on Windows. Alternatively, open Chrome, navigate to chrome://settings/help, or run 'chrome --version' in Command Prompt on Windows.Affected if The installed version cannot be determined or Chrome is not found.
-
Compare the installed version to the affected rangeTake the version number obtained from the previous step and compare it to 148.0.7778.216. Note that versions prior to this (such as 148.0.7778.0 through 148.0.7778.215) are affected.Affected if The installed version is less than 148.0.7778.216.
-
Determine if Headless mode is in useCheck if automated scripts, testing frameworks (such as Puppeteer, Selenium, Playwright), or cron jobs invoke Chrome with the --headless flag or use headless Chrome libraries. Review automation scripts and scheduled tasks for presence of --headless or --headless=new arguments.Affected if Headless mode is actively used and the Chrome version is below 148.0.7778.216.
A user is affected if Google Chrome with a version below 148.0.7778.216 is installed AND Headless mode is being used, as the vulnerability resides specifically in Chrome's Headless mode implementation.

dbcve · scoped148.0.7778.216
Update Google Chrome to version 148.0.7778.216 or later. Organizations using Headless Chrome in automated testing or web scraping applications should prioritize this update and verify that their Chromium-based tools (Puppeteer, Playwright, Selenium, etc.) are using the patched browser version.
Chrome version 148.0.7778.216 or later (stable channel)
- Open Google Chrome and navigate to Settings > Help > About Google Chrome
- Verify the current version is below 148.0.7778.216
- If an update is available, click 'Update Google Chrome' and wait for the download to complete
- Restart Chrome to apply the update
- After restart, verify the version is 148.0.7778.216 or higher via Settings > Help > About Google Chrome
