Withdrawn: this CVE is not a vulnerability
The assigning CNA withdrew CVE-2017-20051 on 30 September 2026, and it carries the Rejected state at CVE.org and NVD. It must not be treated as a live finding. Its pre-withdrawal severity, score and exploitability are withheld below; the record itself is kept because withdrawals are reversible and because the reject reason is the correction worth publishing.
CVE-2017-20051
InnoSetup Installer uncontrolled search path
Description
Rejected reason: ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: The sole source documents PE-format conformance defects in innosetup-5.5.9.exe with no exploit, attack path, or untrusted search path condition (CWE-426/427), and the author states Windows loads these files normally; the record's remote/exploited claims are unsupported, as is the product maintainer's contention.
