CVE-2026-25449 — AI Deep Analysis Summary

🚨 **Essence**: PHP Object Injection via untrusted data deserialization. 💥 **Consequences**: Attackers can inject malicious objects, leading to full system compromise, data theft, or service disruption.

🛡️ **Root Cause**: **CWE-502** (Deserialization of Untrusted Data). The plugin fails to validate data before passing it to PHP's `unserialize()` function, allowing object manipulation.

🏢 **Affected**: **shinetheme**'s **Traveler** plugin. 📉 **Versions**: All versions **prior to 3.2.8.1**. WordPress core is mentioned as context, but the flaw is in the plugin.

🕵️ **Hacker Capabilities**: Full **Object Injection**. This can lead to Remote Code Execution (RCE), arbitrary file reads/writes, and complete server takeover due to high CVSS scores (C:H, I:H, A:H).

🔓 **Exploitation Threshold**: **LOW**. CVSS Vector `AV:N/AC:L/PR:N/UI:N` indicates it is **Network-accessible**, **Low Complexity**, requires **No Privileges**, and **No User Interaction**. Extremely easy to exploit.

📦 **Public Exploit**: **No**. The `pocs` array is empty. While references exist, no specific Proof-of-Concept (PoC) code is currently public in this dataset.

🔍 **Self-Check**: Scan for **Traveler** plugin version < **3.2.8.1**. Look for PHP deserialization endpoints in the plugin code. Use DAST scanners targeting CWE-502.

✅ **Fix Status**: **Yes**. Official patch available in version **3.2.8.1**. Update the plugin immediately to resolve the deserialization flaw.

🚧 **No Patch Workaround**: If updating isn't possible, **disable the plugin** immediately. Implement strict WAF rules to block suspicious PHP serialization payloads or `unserialize()` calls.

🔥 **Urgency**: **CRITICAL**. CVSS Score is **High** (implied by H:H:H). Zero-day potential with no auth required. **Patch immediately** to prevent total server compromise.
