CVE-2026-108759 Details
Description
mistral.rs 0.9.0 through 0.9.4 contains a link following vulnerability in mistralrs-code-exec that allows sandboxed shell code to read and overwrite files outside the sandbox via symlinks. Attackers or prompt-injected agents can name symlinks as outputs or reuse sessions with symlinked input paths to access files with the server process's permissions.
A vulnerability in mistral.rs versions 0.9.0 through 0.9.4 allows sandboxed shell code to read and overwrite files outside the designated sandbox area by exploiting symbolic links. This issue arises in the 'mistralrs-code-exec' component, where attackers or prompt-injected agents can manipulate symlinked file paths to access or modify files with the server process's permissions. The vulnerability is rooted in improper link resolution before file access, leading to unauthorized file interactions.
Users can update to mistral.rs version 0.9.5 or later, where this vulnerability has been addressed.
