Regular Expression Denial of Service (ReDoS) in huggingface/transformers

The huggingface/transformers library, versions prior to 4.53.0, is vulnerable to Regular Expression Denial of Service (ReDoS) in the AdamWeightDecay optimizer. The vulnerability arises from the _do_use_weight_decay method, which processes user-controlled regular expressions in the include_in_weight_decay and exclude_from_weight_decay lists. Malicious regular expressions can cause catastrophic backtracking during the re.search call, leading to 100% CPU utilization and a denial of service. This issue can be exploited by attackers who can control the patterns in these lists, potentially causing the machine learning task to hang and rendering services unresponsive.

transformers 资源管理错误漏洞

transformers是Hugging Face开源的一个用于机器学习的应用程序。 transformers 4.53.0之前版本存在资源管理错误漏洞，该漏洞源于_do_use_weight_decay方法处理用户控制的正则表达式时存在缺陷，可能导致正则表达式拒绝服务攻击。
