CVE-2026-84725：Openjdk-orb 未完整修復 cve-2026-15560，EAP 允許未授權類別載入
CVE-2026-84725 - Openjdk-orb: incomplete fix for cve-2026-15560,unauthed class loading via iiop in eap
核心導語: CVE-2026-84725 使 Openjdk‑orb 在 EAP 執行 -secmgr 時，未授權攻擊者可載入並例項化遠端 URL 的任意類別，進而在 EJB 安全攔截前注入惡意程式碼。
此漏洞允許未授權載入遠端類別，對使用 EAP 的企業系統構成重大風險，讀者可評估是否即時更新或限制遠端程式碼載入。
when EAP runs with -secmgr, the openjdk-orb's JDKBridge honours attacker-supplied CDR codebase URLs during object unmarshalling on :3528, allowing an unauthenticated attacker to load and instantiate arbitrary classes from a remote URL in the server JVM before EJB security interceptors run.

The Common Vulnerability Scoring System is a standardized framework for assessing the severity of vulnerabilities in software and systems. We collect and displays CVSS scores from various sources for each CVE.
| Score | Version | Severity | Vector | Exploitability Score | Impact Score | Source |
|---|---|---|---|---|---|---|
| CVSS 3.1 | HIGH | 53f830b8-0a3f-465b-8143-3b8a9948e749 |
Disable loading remote codebases by default to prevent arbitrary class instantiation.
- Configure ORB to disallow remote codebase loading.
- Do not use the -secmgr option with the openjdk-orb.
- Review and restrict codebase URL sources.
- Apply security patches for affected JDK versions.
