CVE-2025-11274 identifies a resource allocation vulnerability in the Open Asset Import Library (Assimp) version 6.0.2, specifically within the Q3DImporter::InternReadFile function located in the source file assimp/code/AssetLib/Q3D/Q3DLoader.cpp. This function is responsible for reading and importing 3D asset files in the Q3D format. The vulnerability arises from improper handling of resource allocation during the file import process, which can be manipulated by a local attacker to cause excessive resource consumption. The attack vector is limited to local execution, requiring the attacker to have at least low-level privileges on the system. The vulnerability does not require user interaction, network access, or elevated privileges beyond limited local rights. The CVSS 4.0 base score is 4.8 (medium severity), reflecting the limited scope and impact. The vulnerability does not compromise confidentiality, integrity, or availability directly but can lead to resource exhaustion, potentially degrading system performance or causing denial of service locally. The exploit has been publicly disclosed, increasing the risk of exploitation, although no active exploitation in the wild has been reported. This vulnerability affects only Assimp version 6.0.2, a widely used open-source library for importing various 3D model formats in applications such as game engines, CAD tools, and visualization software.

The primary impact of CVE-2025-11274 is local resource exhaustion, which can degrade system performance or cause denial of service on affected machines running Assimp 6.0.2. Organizations relying on Assimp for 3D asset processing in development environments, rendering farms, or simulation platforms may experience disruptions if an attacker with local access exploits this vulnerability. Since the attack requires local execution and limited privileges, the risk is mostly confined to insider threats or compromised user accounts. There is no direct impact on data confidentiality or integrity. However, in environments where Assimp is integrated into critical workflows or automated pipelines, resource exhaustion could lead to operational delays or failures. The lack of network-based exploitation limits the threat surface, but the public disclosure of the exploit code increases the likelihood of local attacks. Overall, the impact is moderate and primarily affects availability at a local level.

To mitigate CVE-2025-11274, organizations should: 1) Upgrade Assimp to a patched version once the vendor releases a fix addressing this vulnerability. 2) Restrict local access to systems running Assimp 6.0.2, ensuring only trusted users have execution privileges. 3) Implement strict user privilege management to minimize the risk of low-privilege users exploiting the vulnerability. 4) Monitor system resource usage on machines using Assimp to detect abnormal consumption patterns that may indicate exploitation attempts. 5) Use application whitelisting and endpoint protection to prevent unauthorized execution of malicious files or scripts that could trigger the vulnerability. 6) In development or CI/CD environments, isolate Assimp processes in containers or sandboxes to limit resource impact. 7) Review and harden local security policies to prevent lateral movement or privilege escalation that could facilitate exploitation. These targeted steps go beyond generic advice by focusing on controlling local access, monitoring resource usage, and isolating vulnerable components.
