What to check
- Applies to
- The 11 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
CERT-FR published an advisory covering multiple vulnerabilities in GitLab Community Edition (CE) and Enterprise Edition (EE). The flaws affect versions 19.3.x prior to 19.3.3, 19.4.x prior to 19.4.1, and all versions prior to 19.2.7. Collectively, the vulnerabilities could allow an attacker to achieve arbitrary code execution, compromise data confidentiality and integrity, bypass security policies, and conduct remote indirect code injection (cross-site scripting).
Eleven CVEs are referenced in the bulletin (CVE-2026-10518, CVE-2026-4523, CVE-2026-84739, CVE-2026-89078, CVE-2026-8937, CVE-2026-92470, CVE-2026-92529, CVE-2026-92530, CVE-2026-92628, CVE-2026-92874, CVE-2026-93577), tied to GitLab's own security release dated 23 September 2026. No detail is given on individual vulnerability mechanics or exploitation status in this advisory.
Defenders running self-hosted GitLab CE/EE should prioritize upgrading to the fixed versions (19.4.1, 19.3.3, or 19.2.7 and later) referenced in GitLab's official patch release notes. No in-the-wild exploitation is mentioned in this advisory; treat as a routine but timely patch action given the range of impacts including RCE.

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.
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 16,433 reports from 149 sources, 661 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, not the rest of the week's. Nothing is charged unless you subscribe.
