CVE-2025-8095 PUBLISHED

Recoverable obfuscation using the OECH1 prefix encoding in OpenEdge

Assigner: ProgressSoftware
Reserved: 23.07.2025 Published: 14.04.2026 Updated: 14.04.2026

The OECH1 prefix encoding is intended to obfuscate values across the OpenEdge platform. It has been identified as cryptographically weak and unsuitable for stored encodings and enterprise applications. OECH1 encodings should be considered exploitable and immediately replaced by any other supported prefix encoding, all of which are based on symmetric encryption.
