# CVE-2026-115905

> 10.0 CRITICAL · 🧪 PoC

## Beschreibung

zip is a zip library for Rust that supports reading and writing simple ZIP files. Through 9.0.4, ZipArchive treats Central Directory File Header filenames as authoritative while ZipStreamReader extracts using Local File Header filenames without reconciling the duplicate metadata in src/read/stream.rs. A crafted archive can therefore appear benign to a component that inspects the central directory but cause a streaming extractor to write a different attacker-selected path and content, potentially overwriting files used by a downstream service. This issue is fixed in version 9.0.5.

## Schwachstellen-Klasse

- **CWE-20** — Improper Input Validation
  The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
- **CWE-436** — Interpretation Conflict
  Product A handles inputs or steps differently than Product B, which causes A to perform incorrect actions based on its perception of B's state.
