The executable loads a malicious version.dll from the application directory instead of the Windows System32 directory, permitting an attacker to run arbitrary code with the privileges of the current user.

The vulnerability is not listed in the CISA KEV catalog. The attack vector is inferred to be local: an attacker must place a malicious version.dll in the application\u2019s directory to trigger the exploit. However, because many users run the portable executable from personal folders, the risk to individual installations remains significant once the issue is publicized. Currently, no patch exists, so the risk is mitigated only by preventing execution from untrusted directories or waiting for a vendor fix."}}}}, "created": "2026-03-23T09:52:41.211580+00:00", "updated": "2026-03-29T20:28:52.915735+00:00", "vendors": ["nickemanarin", "nickemanarin$PRODUCT$screentogif"]}
