Q: What can hackers do? (Privileges/Data)

🕵️ **Attacker Action**: Remote Code Execution (RCE) via SpEL injection. 🔓 **Privileges**: System-level access (S:U, C:H, I:H, A:H). 💾 **Data**: Complete confidentiality and integrity loss.

Q: Is exploitation threshold high? (Auth/Config)

🚪 **Auth**: None required (PR:N). 🌐 **Network**: Remote (AV:N). 🎯 **Complexity**: Low (AC:L). 👤 **UI**: No interaction needed (UI:N). 📉 **Threshold**: **Very Low**.

Q: Is there a public Exp? (PoC/Wild Exploitation)

📜 **Public Exp**: No PoCs listed in data (pocs: []). 🔥 **Wild Exp**: Unknown status. ⚠️ **Risk**: High potential due to low exploitation barrier.

Q: How to self-check? (Features/Scanning)

🔎 **Check**: Scan for `SimpleVectorStore` usage. 🧪 **Test**: Look for SpEL filter expressions with user input. 🛠️ **Tool**: Use SAST tools to detect unsafe SpEL concatenation.

Q: Is it fixed officially? (Patch/Mitigation)

🛡️ **Fix**: Upgrade to **Spring AI 1.0.5** or **1.1.4**. 📝 **Ref**: [Spring Security Advisory](https://spring.io/security/cve-2026-22738). ✅ **Status**: Patch available.

Q: What if no patch? (Workaround)

🚧 **Workaround**: Sanitize/Validate all input used in `SimpleVectorStore` filters. 🚫 **Block**: Prevent user-controlled strings from becoming SpEL keys. 🔄 **Isolate**: Restrict vector store access if possible.

Q: Is it urgent? (Priority Suggestion)

🔥 **Priority**: **CRITICAL**. ⏱️ **Urgency**: Immediate action required. 📉 **CVSS**: 9.8 (Critical). 🚀 **Action**: Patch now to prevent RCE.

Question 1

What is this vulnerability? (Essence + Consequences)

Accepted Answer

🚨 **Essence**: A critical SpEL injection flaw in VMware Spring AI.
💥 **Consequences**: Attackers can execute arbitrary code via malicious filter expressions.
📉 **Impact**: Full system compromise (High CVSS).

Question 2

Root Cause? (CWE/Flaw)
