Description

A flaw was found in Netty's `netty-codec-http` component. A remote attacker could exploit this vulnerability by sending a specially crafted HTTP/1.1 chunk-size token that includes post-digit whitespace. This incorrect parsing of the chunk size can lead to HTTP request smuggling. This allows an attacker to bypass security controls or access unauthorized resources in proxy/backend deployments.

CVE-2026-77875

The application protects access through its calculator-style vault passcode, but the stored data is not bound to that authentication boundary. A local actor who can access shared external storage, such as through an authorized non-root ADB shell or another local file-reading context with suitable storage access, can copy the SQLite database and media files directly without entering the vault passcode.
