CERT-FR Flags Firefox Android Flaw
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 a vulnerability in Firefox for Android versions before 158.0.2, impact unspecified by Mozilla; patch available.
CERT-FR published an advisory referencing a Mozilla security bulletin (MFSA2026-116) that discloses a vulnerability affecting Firefox for Android versions prior to 158.0.2. Mozilla has not specified the precise nature of the security issue, and the advisory does not indicate whether the flaw is being actively exploited in the wild. The risk level is listed as unspecified by the vendor.
Defenders should ensure Firefox for Android is updated to version 158.0.2 or later to remediate the issue identified as CVE-2026-113470. No further technical detail, exploitation status, or affected component information is provided in the source material beyond the version threshold and the official Mozilla advisory reference.

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 13,960 reports from 143 sources, 519 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.
