Summary
SecureDrop Client to aplikacja desktopowa dla dziennikarzy, która umożliwia bezpieczną komunikację ze źródłami i obsługę zgłoszeń. W wersjach 0.17.4 i poniżej, skompromitowany SecureDrop Server może uzyskać wykonanie kodu na maszynie wirtualnej Klienta poprzez wykorzystanie niewłaściwej walidacji nazw plików podczas ekstrakcji archiwów gzip, co pozwala na nadpisywanie krytycznych plików, takich jak baza danych SQLite.
Risk Assessment
Mimo wysokiej złożoności ataku, podatność ma wysoką ocenę ze względu na znaczący wpływ na poufność, integralność i dostępność odszyfrowanych zgłoszeń źródłowych. Wymaga wcześniejszego skompromitowania dedykowanego SecureDrop Server, który jest zabezpieczony i dostępny tylko przez usługi ukryte Tor.
Recommendation
Zaleca się aktualizację do wersji 0.17.5, w której problem został naprawiony. Należy również monitorować bezpieczeństwo SecureDrop Server, aby zapobiec jego kompromitacji.

Original NVD description (English source)
SecureDrop Client is a desktop app for journalists to securely communicate with sources and handle submissions on the SecureDrop Workstation. In versions 0.17.4 and below, a compromised SecureDrop Server can achieve code execution on the Client's virtual machine (sd-app) by exploiting improper filename validation in gzip archive extraction, which permits absolute paths and enables overwriting critical files like the SQLite database. Exploitation requires prior compromise of the dedicated SecureDrop Server, which itself is hardened and only accessible via Tor hidden services. Despite the high attack complexity, the vulnerability is rated High severity due to its significant impact on confidentiality, integrity, and availability of decrypted source submissions. This issue is similar to CVE-2025-24888 but occurs through a different code path, and a more robust fix has been implemented in the replacement SecureDrop Inbox codebase. The issue has been fixed in version 0.17.5.
