CVE-2022-1197 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. When importing a revoked key that specified key compromise as the revocation reason, Thunderbird did not update the existing copy of the key that was not yet revoked, and the existing key was kept as non-revoked. Revocation statements that used another revocation reason, or that didn't specify a revocation reason, were unaffected. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
