CVE-2026-30862 — AI Deep Analysis Summary

🚨 **Essence**: Stored XSS in Appsmith's Table Widget due to missing HTML sanitization.…

🛡️ **Root Cause**: **CWE-79** (Improper Neutralization of Input During Web Page Generation). The Table Widget rendering pipeline fails to clean HTML inputs, allowing raw script execution.

👥 **Affected**: **Appsmith** open-source platform. Specifically versions **prior to 1.96**. Vendor: **appsmithorg**. Internal admin users are the primary target audience.

💰 **Attacker Actions**: With low privileges, hackers can execute arbitrary JavaScript in victims' browsers. This enables **stealing session cookies**, **phishing credentials**, and **taking over admin accounts**.

🔓 **Exploitation Threshold**: **Medium**. Requires **PR:L** (Low Privileges) and **UI:R** (User Interaction). The attacker needs to inject data into a table, and a victim (likely an admin) must view it.…

📦 **Public Exploit**: **No**. The `pocs` field is empty. While the vulnerability is confirmed, no public Proof-of-Concept (PoC) or wild exploitation code is currently available in the provided data.

🔍 **Self-Check**: Scan for Appsmith instances running version **< 1.96**. Check if Table Widgets render raw HTML without sanitization. Look for stored XSS payloads in table data fields.

✅ **Official Fix**: **Yes**. The vulnerability is addressed in **Appsmith version 1.96** and later. Users must upgrade immediately to patch the HTML cleaning flaw.

🚧 **No Patch Workaround**: If upgrading is impossible, **disable HTML rendering** in Table Widgets if possible. Restrict access to internal apps to trusted users only.…

⚠️ **Urgency**: **HIGH**. CVSS Score indicates **Critical** impact (C:H, I:H, A:H). Although exploitation requires user interaction, the consequence (Account Takeover) is severe.…
