CVE-2026-81684
MediumCVSS 6.2Summary
In openssl_encrypt (pip package openssl-encrypt) versions <= 1.4.8, the desktop GUI passes the steganography password to the CLI child process on the command line via the --stego-password argument (on both encrypt and decrypt paths) instead of via an environment variable as done for the main password. Any local user can read the steganography password from /proc/<pid>/cmdline for the lifetime of the subprocess. Fixed in 1.4.9.
Risk Assessment
The risk is the exposure of the steganography password to local users, potentially leading to unauthorized access to hidden data.
Recommendation
Upgrade to version 1.4.9, which passes the password via an environment variable, and avoid using older versions on multi-user systems.
