CVE-2026-14610 Open Asset Import Library CVE debrief

Who should care

Defenders of systems using Open Asset Import Library Assimp, especially those handling CSM files, should assess exposure and apply patches. System administrators and security teams responsible for managing and securing systems that utilize Open Asset Import Library Assimp should prioritize patching and review compensating controls. Users of affected systems should verify patch application and restrict handling of untrusted CSM files to prevent exploitation

Why it matters

CVE-2026-14610 is a heap-based buffer overflow in Open Asset Import Library Assimp's CSM file handling. Local execution is required. A patch is available.

• Local exploitation could lead to system compromise
• Successful exploitation requires local execution of malicious CSM files
• Verify patch application on vulnerable systems
• Restrict handling of untrusted CSM files

Technical summary

The CSMImporter::InternReadFile function in CSMLoader.cpp of Open Asset Import Library Assimp up to 6.0.5 is vulnerable to a heap-based buffer overflow when processing CSM files. The vulnerability requires local execution to exploit and is restricted to local interaction. The affected function does not properly validate input, leading to a buffer overflow condition. Users should apply patches to fix this issue and restrict handling of untrusted CSM files to mitigate exposure. The vulnerability has been made public and a patch is available.

Defensive priority

Apply patch eb84eec580d3f4ba2f0fd87409b7d0744620f11e to vulnerable systems handling CSM files.

Recommended defensive actions

• Apply patch eb84eec580d3f4ba2f0fd87409b7d0744620f11e
• Inventory systems using Open Asset Import Library Assimp
• Restrict local execution of untrusted CSM files
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
