Nextcloud is an open source content collaboration platform. In Nextcloud Server from versions 31.0.0 to before 31.0.12, and 32.0.0 to before 32.0.3, a missing check of a relation allowed authenticated users with access to any file comment, to read the content of all comments. It is recommended that the Nextcloud Server is upgraded to 31.0.12 or 32.0.3. It is recommended that the Nextcloud Enterprise Server is upgraded to 21.0.9.20, 22.2.10.35, 23.0.12.31, 24.0.12.30, 25.0.13.25, 26.0.13.22, 27.1.11.22, 28.0.14.13, 29.0.16.10, 30.0.17.5, 31.0.12 or 32.0.3
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.8, indicating it can be exploited remotely over the network with relatively low complexity though user interaction is required requiring only low-level privileges . The vulnerability impacts confidentiality (data exposure), for affected systems. Impacting 1 product from nextcloud 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 nextcloud'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.
