CVE-2022-29249Network attack vector

Plaintext recovery via reversible one-way hashing

Published May 24, 2022 · Updated Apr 23, 2025

Weak cryptography in JavaEZ 1.6 allows remote attackers to recover plaintext from text protected by the library. The advisory identifies reversible one-way hashing and a broken or risky cryptographic algorithm, but neither it nor the release notes discloses the affected API or cryptographic operation. Exploitation requires access to protected text and exposes only its confidentiality; no data modification or service interruption is reported.
