Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of the transformers package before 5.5.0 are affected. In the LightGlue model loading path, an attacker who controls a model repository can get arbitrary code to run during model initialization, even when the user loads the model with trust_remote_code set to False. The victim only needs to load the attacker's model. Upgrade to transformers 5.5.0 or later.
