Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The openssl_encrypt package (pip openssl-encrypt) versions 1.4.8 and earlier store an mTLS client private key in cleartext in a world-readable (0644) SharedPreferences file when it is entered through the desktop GUI's Settings screen. A local attacker with file system access can read the exposed private key. Upgrade to version 1.4.9, which writes the key to a dedicated 0600 file, keeps only its path in SharedPreferences, and scrubs existing cleartext values.

Written 5 Nov 2026.
