Because these libraries may be resolved and loaded from user‑writable locations, a local attacker can place a malicious library there and have it loaded with SYSTEM privileges, resulting in local privilege escalation and arbitrary code execution.","publishedAt":"2026-04-01T01:40:36.975Z","updatedAt":"2026-04-02T02:11:52.749Z","severity":{"score":7.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Foxit"},"assigner":"Foxit","products":["Foxit Software Inc.
