An issue was discovered in Enigmail before 1.9.9. A remote attacker can obtain cleartext content by sending an encrypted data block (that the attacker cannot directly decrypt) to a victim, and relying on the victim to automatically decrypt that block and then send it back to the attacker as quoted text, aka the TBE-01-005 "replay" issue.

Exploit prediction (EPSS)

1.35% probability of exploitation in the next 30 days, higher than 72% of all scored CVEs.
