Hello,
At CT-RSA 2021 Venema and Alpar presented attacks against 11 ABE schemes and two of them are implemented in the last version of CHARM: DAC-MACS and MA-ABE-YJ14:
Moreover, the YCT14 scheme was broken in 2019 and is also implemented in CHARM: https://github.com/JHUISI/charm/blob/dev/charm/schemes/abenc/abenc_yct14.py
It is possible to mount decryption attacks against them.
