SCA: security update for transformers (GHSA-4w7r-h757-3r74)
high Tenable Self-Hosted Container Security Plugin ID 435404
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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. (CVE-2025-6921)
