PYSEC-2026-3817 Trestle has Server-Side Template Injection (SSTI) via Recursive Template Re-evaluation of Untrusted Data

Impact A Server-Side Template Injection SSTI vulnerability exists in multiple locations of trestle's Jinja2 rendering pipeline due to a systemic pattern: untrusted data is re-parsed as Jinja2 template source code without sandboxing. This advisory tracks the root cause across all affected code...

GitPython: Unguarded git option forwarding in Repo.init enables arbitrary command execution via --template clone hooks

SummaryRepo.init forwards kwargs verbatim to git init with no unsafe-option guard and no allowunsafeoptions parameter. git init --template= copies /hooks/ into the new repo's .git/hooks, so an attacker-controlled template kwarg plants a hook that executes on the next git operation → arbitrary cod...

PYSEC-2026-3929 Transformers save_pretrained path traversal allows arbitrary file writes through chat template names

A vulnerability in huggingface/transformers versions 5.10.0 allows an attacker to perform arbitrary file writes via path traversal. The issue resides in the savepretrained methods of PreTrainedTokenizerBase and ProcessorMixin, where keys from the chattemplate dictionary are used directly as...

PYSEC-2026-3830 Document Merge Service vulnerable to RCE via SSTI (xlsx tempaltes)

Impact A remote code execution RCE via server-side template injection SSTI allows for user supplied code to be executed in the server's context where it is executed as the document-merge-server user with the UID 901 thus giving an attacker considerable control over the container. The vulnerabilit...
