GitLab has remediated an issue in GitLab CE/EE affecting all versions from 15.9 before 18.10.8, 18.11 before 18.11.5, and 19.0 before 19.0.2 that under certain conditions, could have allowed an unauthenticated user to impersonate the GitLab Support Bot and inject arbitrary content via a specially crafted Service Desk email reply due to improper neutralization in email template processing.
This vulnerability carries a LOW severity rating with a CVSS v3.1 score of 2.6, indicating it can be exploited remotely over the network but requires specific conditions to be met though user interaction is required requiring only low-level privileges . The vulnerability impacts limited integrity, for affected systems. Impacting 1 product from gitlab organizations running these solutions should prioritize assessment and patching.
Reported in 2026, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For gitlab's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
