Echo: sentence-transformers: security update to 5.6.0

critical Tenable Self-Hosted Container Security Plugin ID 471220

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- sentence-transformers contains a security control bypass vulnerability that allows attackers to achieve
arbitrary code execution by exploiting a logic flaw in the import_module_class helper within
sentence_transformers/util/misc.py, where the guard condition includes an 'or
os.path.exists(model_name_or_path)' clause that satisfies the trust gate whenever the supplied path exists
on the local filesystem, regardless of the trust_remote_code=False argument. Attackers who can control or
influence the contents of a model directory on disk can place malicious Python files such as modeling_*.py
referenced via modules.json, causing the code to execute at import time when an application loads the
model with SentenceTransformer(path, trust_remote_code=False), bypassing the documented security contract
and achieving code execution within the loading process. (CVE-2026-68770)

Solution

Update the sentence-transformers library and its related packages to version 5.6.0 or later.
