Description

This security bulletin contains information about 1 vulnerability.


1) Uncontrolled Memory Allocation (CVE-ID: CVE-2025-53893)

CWE-ID: CWE-789 - Uncontrolled Memory Allocation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to cause a denial of service.

The vulnerability exists due to memory allocation with excessive size value in the file reading logic of the /api/resources/{file-name} endpoint when reading a previously uploaded oversized file. A remote user can upload a very large file and then request it to be opened to cause a denial of service.

The issue occurs because the application attempts to load the entire file content into memory during read operations.
