CVE-2026-118994

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.

Perl 版本低于 0.62.0 的 CallBackery 存在日志注入漏洞，攻击者可通过在登录名中插入换行符实施攻击。函数在将登录名写入应用日志时，未对控制字符进行转义处理。由于 RPC 方法无需身份验证，攻击者可在登录名中构造包含换行符及符合日志记录格式文本的字符串，从而向日志中注入伪造的记录。未认证的攻击者可利用此漏洞伪造日志记录，例如生成显示其指定 IP 地址的管理员成功登录的虚假日志条目。

Vulnerability Title

CallBackery versions before 0.62.0 for Perl allow log injection via newlines in the login name

Source: CVE Program / CVE List V5

Vulnerability Description

CallBackery versions before 0.62.0 for Perl allow log injection via newlines in the login name. login() writes the login name to the application log without escaping control characters. The login RPC method needs no authentication, so a name containing a newline followed by text in the log record format adds a forged record. An unauthenticated attacker can forge log records, such as a successful administrator login from an address of their choosing.
