CERT-FR flags Chrome 156 vulnerabilities
Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.
CERT-FR advises multiple Chrome vulnerabilities before version 156.0.8078.47/48, with no confirmed exploitation or severity detail from Google.
CERT-FR has published an advisory covering a large batch of vulnerabilities affecting Google Chrome for Windows, Linux, and Mac prior to versions 156.0.8078.47 (Windows/Linux) and 156.0.8078.48 (Mac). The advisory references Google's own stable channel update blog post from October 20, 2026, and enumerates several hundred CVE identifiers associated with the release, though no specific technical details, exploitation status, or severity ratings are provided by the publisher beyond stating the impact is 'unspecified by the vendor.'
Defenders should treat this as a routine browser patch cycle: update affected Chrome installations to the fixed versions as soon as possible via standard update mechanisms. No indicators of compromise, threat actor attribution, or in-the-wild exploitation are mentioned in this advisory. Organizations should consult Google's official release notes for further technical detail on individual flaws and prioritize patching based on their own exposure and any subsequent in-the-wild exploitation reports.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 14,237 reports from 143 sources, 591 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them — about forty a week that are yours, not the four hundred that are not.
