CVE-2026-26286
HighSummary
SillyTavern to lokalnie zainstalowany interfejs użytkownika, który umożliwia interakcję z modelami generacji tekstu oraz obrazów. W wersjach przed 1.16.0 występuje podatność typu Server-Side Request Forgery (SSRF) w punkcie końcowym pobierania zasobów, która pozwala uwierzytelnionym użytkownikom na wykonywanie dowolnych żądań HTTP z serwera oraz odczytywanie pełnej odpowiedzi, co umożliwia dostęp do wewnętrznych usług i zasobów sieci prywatnej.
Risk Assessment
Podatność ta stwarza ryzyko nieautoryzowanego dostępu do wrażliwych danych i usług wewnętrznych, co może prowadzić do poważnych naruszeń bezpieczeństwa w organizacji.
Recommendation
Zaleca się aktualizację do wersji 1.16.0 lub nowszej, aby załatać tę podatność oraz skonfigurowanie listy dozwolonych domen w pliku `config.yaml`.

Original NVD description (English source)
SillyTavern is a locally installed user interface that allows users to interact with text generation large language models, image generation engines, and text-to-speech voice models. In versions prior to 1.16.0, a Server-Side Request Forgery (SSRF) vulnerability in the asset download endpoint allows authenticated users to make arbitrary HTTP requests from the server and read the full response body, enabling access to internal services, cloud metadata, and private network resources. The vulnerability has been patched in the version 1.16.0 by introducing a whitelist domain check for asset download requests. It can be reviewed and customized by editing the `whitelistImportDomains` array in the `config.yaml` file.
