CVE-2026-34524 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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. Prior to version 1.17.0, a path traversal vulnerability in chat endpoints allows an authenticated attacker to read and delete arbitrary files under their user data root (for example secrets.json and settings.json) by supplying avatar_url="..". EPSS estimates a 0.57% chance of exploitation in the next 30 days.
