CVE-2026-81719— openssl_encrypt before 1.4.9 Remote Code Execution via Plugin

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.

在版本 1.4.9 之前，openssl_encrypt 对不可信的第三方插件执行缺乏足够的管控：插件签名策略的默认值为 WARN，导致未签名或无法验证的非内置插件在导入时即被编译并在宿主进程中执行，且发生在运行时沙箱安装之前。唯一的默认防护是一道不完整且可被绕过的 AST 拒绝列表。若用户被诱导加载了攻击者的插件，将会导致以运行 openssl_encrypt 的用户权限执行任意代码。该问题已在 1.4.9 中修复：将非内置插件的签名策略默认值改为 ENFORCE。

Vulnerability Title
openssl_encrypt before 1.4.9 Remote Code Execution via Plugin
Source: CVE Program / CVE List V5
Vulnerability Description
openssl_encrypt before 1.4.9 executes untrusted third-party plugins with insufficient controls: the plugin signature policy defaulted to WARN, so an unsigned/unverifiable non-built-in plugin was compiled and executed in the host process at import time, before the runtime sandbox is installed. The only default gate was an incomplete, bypassable AST denylist. If a user is induced to load an attacker's plugin, this results in arbitrary code execution with the privileges of the user running openssl_encrypt. Fixed in 1.4.9 by defaulting the signature policy to ENFORCE for non-built-in plugins.
