DSpace: Improper Control of Generation of Code

CVE-2026-49832 is a high-severity improper control of generation of code vulnerability in DSpace, with a CVSS 3.1 base score of 8.0 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. Affected DSpace versions: >= 8.0-rc1, < 8.4; >= 9.0-rc1, < 9.3; = 10-rc1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.87% chance of exploitation within 30 days, higher than 59% of scored CVEs.

Official description

DSpace open source software is a repository application which provides durable access to digital resources. From versions 8.0-rc1 to before 8.4, versions 9.0-rc1 to before 9.3, and version 10-rc1, Remote Code Execution (RCE) is possible via Velocity Templates used by DSpace for COAR Notify/LDN messages. This issue has been patched in versions 8.4, 9.3, and 10.0.

The underlying weakness: Improper Control of Generation of Code

The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

How developers prevent this class of flaw

  • Refactor your program so that you do not have to dynamically generate code.
  • Run your code in a jail or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product. Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection. This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise. Be careful to avoid CWE-243 and other weaknesses related to jails.
  • Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.
