Critical (9.3) in jahlives openssl encrypt. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in openssl-encrypt 1.4.9.
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.
