Jenkins before versions 2.44, 2.32.2 uses AES ECB block cipher mode without IV for encrypting secrets which makes Jenkins and the stored secrets vulnerable to unnecessary risks (SECURITY-304).
Weakness
The product does not implement a required step in a cryptographic algorithm, resulting in weaker encryption than advertised by the algorithm.
