Vulnerability Title
openssl_encrypt before 1.4.9 Authentication Bypass via Recovery Slot Removal
Source: CVE Program / CVE List V5
Vulnerability Description
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.
