  • Follow vendor security advisories [S0]
Chain of evidence and sources3 verified claims

Strands Agents Tools 0.8.6 öncesi sürümlerdeki ortam aracında gizli maskeleme atlatma açığı bulunmaktadır.

Hazırlanan bir komut istemi, gizli maskeleme özelliğini devre dışı bırakarak ana makine ortam değişkenlerinin düz metin olarak elde edilmesini sağlayabilir.

Kullanıcıların sürüm 0.8.6 veya sonrasına yükseltme yapması ve etkilenen ortamdaki kimlik bilgilerini döndürmesi gerekmektedir.

Show the technical text from the sources

Improper neutralization of input used for LLM prompting in the environment tool in Strands Agents Tools before 0.8.6 might allow remote actors to obtain the agent host's environment variables in cleartext, including cloud credentials and API keys, via a crafted prompt that disables the tool's secret masking. To remediate this issue, users should upgrade to version 0.8.6 or later and rotate any credentials that were present in the environment of agents that loaded the environment tool.
