Technical details
parsel implements insecure cryptography by using AES-256-CBC encryption without authenticated encryption or integrity verification (CWE-327). The vulnerable component is the core encryption mechanism, which is exploitable via a network or local vector if an attacker can intercept and modify ciphertext. An attacker can perform bit-flipping attacks to alter encrypted messages without invalidating the ciphertext, allowing unauthorized modification of protected data. The package is deprecated and will not receive updates; users should migrate to alternative encryption libraries.
