CVE-2026-81695— openssl_encrypt before 1.4.9 Terminal Injection via key_id
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_encrypt 在 1.4.9 之前的版本，在解密时的自动检测过程中，未能对攻击者可控的 key_id 值进行转义处理，导致其直接输出到标准错误流（stderr）。攻击者可以构造包含转义序列的恶意 key_id，从而重新绘制终端输出，并伪造认证验证块。
