NVD description
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: sentence-transformers Security Control Bypass - What It Means for Your Business and How to Respond https://hubs.li/Q04xkCsd0
Post summary
The post discloses CVE‑2026‑68770, a security‑control bypass in the sentence‑transformers library, detailing the vulnerability but offering no PoC, active exploitation, or specific remediation steps.
🚨Critical - sentence-transformers Trust Gate Bypass to Import-Time RCE (CVE-2026-68770) sentence-transformers import_module_class() in sentence_transformers/util/misc.py can be tricked by a path-exists check so the trust gate passes even when trust_remote_code=False. If an attacker can control a local model dir, they can drop modules.json + malicious modeling_*.py that executes on import during model load, leading to arbitrary code execution. 👉Affected: sentence-transformers (versions TBD)
Post summary
The post announces CVE-2026-68770, detailing a trust-gate bypass in sentence-transformers that permits local directories to execute arbitrary code during model import, thereby presenting an RCE vector; no patch or exploitation evidence is provided.
