A vulnerability in NumPy could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.
The vulnerability is due to the unsafe use of the pickle Python module by the affected software. An attacker could exploit this vulnerability by persuading a user to access a link or file that submits malicious input to the targeted system. If the attacker makes a numpy.load call to load the malicious content, the attacker could execute arbitrary code.
Proof-of-concept (PoC) code that demonstrates an exploit of this vulnerability is publicly available.
NumPy has confirmed the vulnerability; however, software updates are not available.
To exploit this vulnerability, an attacker may persuade a user to load malicious content with the affected application on a targeted system by using misleading language and instructions.
