CVE-2026-81680— openssl_encrypt before 1.4.9 Authentication Bypass via Recovery Slot Removal

Quick assessment

Affected
jahlives openssl_encrypt
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenSSL 在 1.4.9 之前的版本中,OpenSSL 的加密函数(openssl_encrypt)未能对信封格式加密文件中的“恢复槽位(recovery slots)”的存在性进行认证。这意味着攻击者可以在不重新加密负载(payload)的情况下,移除恢复槽位。具体而言,攻击者可以通过修改文件头来删除恢复槽位字段,从而绕过认证机制,悄悄地移除所有者有意添加的恢复路径。

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.
