- The 13 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.
The French CERT (CERT-FR) issued an advisory regarding multiple vulnerabilities discovered in GitLab Community Edition (CE) and Enterprise Edition (EE). The affected versions include 19.0.x prior to 19.0.3, 19.1.x prior to 19.1.1, and all versions prior to 18.11.6. The vulnerabilities enable various attack vectors including data confidentiality breaches, server-side request forgery (SSRF), cross-site scripting (XSS), and security policy bypass.
GitLab released patches on June 24, 2026 addressing thirteen distinct CVEs. The advisory identifies specific risks including unauthorized access to sensitive data, the ability to forge requests from the server side, and remote code injection through XSS vulnerabilities. Organizations running affected GitLab versions should prioritize patching to mitigate these risks.
The CERT-FR advisory recommends immediate consultation of GitLab's security bulletin for obtaining and applying the necessary patches. Given GitLab's widespread use in software development environments, these vulnerabilities represent a significant exposure for organizations hosting their own GitLab instances.

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 16,436 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.
