CVE-2021-38599: Wal-G Project Wal-G

High severity, CVSS 7.5. EPSS: 0.8% chance of exploitation in the next 30 days.

WAL-G before 1.1, when a non-libsodium build (e.g., one of the official binary releases published as GitHub Releases) is used, silently ignores the libsodium encryption key and uploads cleartext backups. This is arguably a Principle of Least Surprise violation because "the user likely wanted to encrypt all file activity."

Affected products

• Wal-G Project Wal-G: before 1.1 (fixed in 1.1)
