Quick assessment
Affected
Red Hat Red Hat Enterprise Linux 10
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.
FreeIPA是FreeIPA组织开源的一款身份认证与权限管理产品。 FreeIPA存在代码注入漏洞，该漏洞源于idp-add命令中--organization/--base-url参数输入验证不足，在实施相应LDAP访问控制检查之前调用受限的eval()函数，导致任何已认证的IPA主体（无论权限级别）能够枚举并读取受影响服务器进程的环境变量，并可能通过内存耗尽造成拒绝服务。

Vulnerability Title
Freeipa: idm: freeipa: idp-add eval() reachable before authorization check allows environment disclosure and denial of service
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in FreeIPA's idp-add command, where insufficiently validated --organization/--base-url input reaches a constrained eval() call before the corresponding LDAP access control check is enforced. This allows any authenticated IPA principal, regardless of privilege level, to enumerate and read the environment variables of the affected server process and to cause denial of service via memory exhaustion.
