From f71b60443855ddef82170e64a6c4d24a1d415625 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 19 Nov 2025 04:24:14 +0000 Subject: [PATCH 1/5] security: add weights_only=True to all torch.load() calls Fixes a critical security vulnerability where malicious model checkpoints could execute arbitrary code through pickle deserialization. Changes: - wan/modules/vae.py: Add weights_only=True to torch.load() - wan/modules/clip.py: Add weights_only=True to torch.load() - wan/modules/t5.py: Add weights_only=True to torch.load() This prevents arbitrary code execution when loading untrusted checkpoints while maintaining full compatibility with legitimate model weights. Security Impact: Critical - prevents RCE attacks Breaking Changes: None - weights_only=True is compatible with all standard PyTorch state_dict files --- wan/modules/clip.py | 2 +- wan/modules/t5.py | 2 +- wan/modules/vae.py | 2 +- 3 files changed, 3 insertions(+), 3 deletions(-) diff --git a/wan/modules/clip.py b/wan/modules/clip.py index 42dda04..7bf859d 100644 --- a/wan/modules/clip.py +++ b/wan/modules/clip.py @@ -516,7 +516,7 @@ class CLIPModel: self.model = self.model.eval().requires_grad_(False) logging.info(f'loading {checkpoint_path}') self.model.load_state_dict( - torch.load(checkpoint_path, map_location='cpu')) + torch.load(checkpoint_path, map_location='cpu', weights_only=True)) # init tokenizer self.tokenizer = HuggingfaceTokenizer( diff --git a/wan/modules/t5.py b/wan/modules/t5.py index c841b04..021f1c7 100644 --- a/wan/modules/t5.py +++ b/wan/modules/t5.py @@ -493,7 +493,7 @@ class T5EncoderModel: dtype=dtype, device=device).eval().requires_grad_(False) logging.info(f'loading {checkpoint_path}') - model.load_state_dict(torch.load(checkpoint_path, map_location='cpu')) + model.load_state_dict(torch.load(checkpoint_path, map_location='cpu', weights_only=True)) self.model = model if shard_fn is not None: self.model = shard_fn(self.model, sync_module_states=False) diff --git a/wan/modules/vae.py b/wan/modules/vae.py index 5c6da57..f7bb78a 100644 --- a/wan/modules/vae.py +++ b/wan/modules/vae.py @@ -611,7 +611,7 @@ def _video_vae(pretrained_path=None, z_dim=None, device='cpu', **kwargs): # load checkpoint logging.info(f'loading {pretrained_path}') model.load_state_dict( - torch.load(pretrained_path, map_location=device), assign=True) + torch.load(pretrained_path, map_location=device, weights_only=True), assign=True) return model From 67f00b6f47df751ec9834f61c5469f63762a5ed0 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 19 Nov 2025 04:24:33 +0000 Subject: [PATCH 2/5] test: add comprehensive pytest test suite Implements a production-grade testing infrastructure with 100+ tests covering all core modules and pipelines.

Correction + +**Community Impact**: Use of inappropriate language or other behavior deemed unprofessional or unwelcome in the community. + +**Consequence**: A private, written warning from community leaders, providing clarity around the nature of the violation and an explanation of why the behavior was inappropriate. A public apology may be requested. + +### 2. Warning + +**Community Impact**: A violation through a single incident or series of actions. + +**Consequence**: A warning with consequences for continued behavior. No interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, for a specified period of time. This includes avoiding interactions in community spaces as well as external channels like social media. Violating these terms may lead to a temporary or permanent ban. + +### 3. Temporary Ban + +**Community Impact**: A serious violation of community standards, including sustained inappropriate behavior. + +**Consequence**: A temporary ban from any sort of interaction or public communication with the community for a specified period of time. No public or private interaction with the people involved, including unsolicited interaction with those enforcing the Code of Conduct, is allowed during this period. Violating these terms may lead to a permanent ban. + +### 4. Permanent Ban + +**Community Impact**: Demonstrating a pattern of violation of community standards, including sustained inappropriate behavior, harassment of an individual, or aggression toward or disparagement of classes of individuals. + +**Consequence**: A permanent ban from any sort of public interaction within the community. + +## Attribution + +This Code of Conduct is adapted from the [Contributor Covenant](https://www.contributor-covenant.org), version 2.1, available at https://www.contributor-covenant.org/version/2/1/code_of_conduct.html. + +Community Impact Guidelines were inspired by [Mozilla's code of conduct enforcement ladder](https://github.com/mozilla/diversity). + +For answers to common questions about this code of conduct, see the FAQ at https://www.contributor-covenant.org/faq.
