What to check
- Applies to
- The 2 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- A public exploit is recorded for CVE-2026-19478 (templated); no exploitation in the wild is recorded.
ANSSI (CERT-FR) published an advisory covering multiple vulnerabilities in GitLab Community Edition and Enterprise Edition. The flaws allow an attacker to compromise data integrity and to perform Cross-Site Request Forgery (CSRF) attacks, enabling illegitimate requests to be injected by bouncing off a victim's session.
Two CVEs are referenced: CVE-2026-19478 and CVE-2026-19650. Affected versions span the 19.0.x, 19.1.x, and 19.2.x branches prior to 19.0.8, 19.1.6, and 19.2.4 respectively, as well as all versions prior to 18.11.11. GitLab has released a security bulletin dated 17 August 2026 with corrective patches, and organizations running affected versions are advised to update promptly per the vendor's guidance.
No evidence of active exploitation is mentioned in the advisory. This is a routine vendor patch notice rather than an active-threat report, and the risk profile is consistent with standard vulnerability management processes for GitLab deployments.

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.
