CVE-2025-59489: Unity Runtime before 2025-10-02 on Android, Windows, macOS, and Linux allows argument injection that can result in loading of library code f

Noroxi assessment

Priority: Monitor (action score 29/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.64% (FIRST EPSS); higher than 50.8% of all records.
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Microsoft Mesh for Meta Quest 5.2514; Microsoft Mesh PC Applications 5.2514.

Low priority for now. Upgrade to Microsoft Mesh for Meta Quest 5.2514; Microsoft Mesh PC Applications 5.2514 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Unity Runtime before 2025-10-02 on Android, Windows, macOS, and Linux allows argument injection that can result in loading of library code from an unintended location. If an application was built with a version of Unity Editor that had the vulnerable Unity Runtime code, then an adversary may be able to execute code on, and exfiltrate confidential information from, the machine on which that application is running. NOTE: product status is provided for Unity Editor because that is the information available from the Supplier. However, updating Unity Editor typically does not address the effects of the vulnerability; instead, it is necessary to rebuild and redeploy all affected applications.
