CVE-2026-81680: Jahlives OpenSSL Encrypt

Medium severity, CVSS 5.3. EPSS: 0.2% chance of exploitation in the next 30 days.

openssl_encrypt versions before 1.4.9 fail to authenticate recovery-slot presence in envelope-format encrypted files, allowing attackers to remove recovery slots without re-encrypting the payload. Attackers can modify the file header to delete recovery-slot fields and bypass authentication, silently removing recovery paths the owner deliberately added.

Affected products

• Jahlives OpenSSL Encrypt: before 1.4.9 (fixed in 1.4.9)
