CVE-2026-27709

NanaZip is an open source file archive. Starting in version 5.0.1252.0 and prior to versions 6.0.1638.0 and 6.5.1638.0, NanaZip’s .NET Single File Application parser has an out-of-bounds read vulnerability in manifest parsing. A crafted bundle can provide a malformed RelativePathLength so the parser constructs a std::string from memory beyond HeaderBuffer, leading to crash and potential in-process memory disclosure. Versions 6.0.1638.0 and 6.5.1638.0 fix the issue.
