GitLab has issued critical security updates on June 11, 2025, to address multiple vulnerabilities in both the Community Edition (CE) and Enterprise Edition (EE) of its platform. These patches are crucial for self-managed GitLab installations, with experts urging immediate upgrades to prevent potential exploits. The updates tackle high-severity vulnerabilities that could allow attackers to achieve complete account takeover and compromise enterprise development environments, emphasizing the importance of proactive security measures in DevSecOps environments.

One of the most concerning vulnerabilities, CVE-2025-5121, affects GitLab Ultimate EE customers and carries a CVSS score of 8.5. This missing authorization issue allows attackers with authenticated access to a GitLab instance with a GitLab Ultimate license to inject malicious CI/CD jobs into all future pipelines of any project. This can lead to backdoors being added, validation steps being skipped, and secrets used during the build process being exposed, significantly compromising the software development lifecycle.

Other notable vulnerabilities addressed in this patch release include CVE-2025-4278, an HTML injection vulnerability with a CVSS score of 8.7 that could lead to account takeover, and CVE-2025-2254, a cross-site scripting (XSS) vulnerability, also with a CVSS score of 8.7, allowing attackers to act in the context of legitimate users. GitLab has released versions 18.0.2, 17.11.4, and 17.10.8 for both CE and EE to address these issues, and it's strongly recommended that all affected installations be updated as soon as possible.

@Latest from ITPro //
Europcar Mobility Group has confirmed a data breach affecting potentially up to 200,000 customers. The breach occurred through unauthorized access to the company’s GitLab repositories. According to reports, the stolen data includes source code for Europcar's Android and iOS mobile applications, as well as personal data linked to tens of thousands of customers. This incident raises significant security concerns, as the exposure of source code could potentially reveal vulnerabilities that could be exploited in future attacks.

Europcar is currently assessing the full extent of the damage caused by the breach. Preliminary findings indicate that the compromised data includes names and email addresses of users belonging to the Goldcar and Ubeeqo brands. The compromised records date back as far as 2017 and 2020. Europcar maintains that no financial information, passwords, or biometric details were exposed. The company has notified data protection authorities and has begun the process of informing affected customers about the incident.

The attacker reportedly claimed responsibility for the breach in late March and attempted to extort Europcar, threatening to release 37GB of stolen data. The data allegedly includes internal backups, infrastructure documentation, and application source code. Europcar has denied that all of its GitLab repositories were compromised, but has confirmed that the threat actor accessed over 9,000 SQL files and 269 environment configuration files. The method of access remains unclear, although similar breaches often involve stolen credentials obtained through infostealer malware. The investigation is ongoing.
