CVE-2024-55964

Think of Appsmith as a tool that lets people connect to databases and run queries. This flaw is like having a badly set-up “back door” in the database part of the container: with enough access inside Appsmith, an attacker can make the system run arbitrary commands instead of just running normal database queries. If someone gets through to misuse those features, they could take over the Appsmith container and potentially harm your systems or data.

This matters if your business runs Appsmith (the service and its built-in database/datasource and query features) on a version earlier than 1.52. It’s reachable in the default configuration, but attackers still need to access Appsmith, log in, create a datasource, create a query, and execute it. If nobody can reach your Appsmith from the network and only trusted accounts can log in, the risk is much lower.

This is urgent because the vulnerability allows remote code execution and is reachable in the default setup. While an attacker needs to log in and use datasource/query execution steps, it still gives a direct path to run commands inside your Appsmith container. Treat this as a priority fix because the vendor patch exists (fixed in 1.52) and attackers may target exposed instances.

Confirm exposure

• Identify your Appsmith version (from the Appsmith UI or your deployment configuration) and check whether it is before 1.52.
• Verify whether Appsmith is reachable from the internet or other untrusted networks (e.g., public IP/port exposure).
• Confirm whether accounts with permission to create datasources and execute queries exist (and whether those accounts are tightly controlled).

Upgrade remediation (primary fix)

• Upgrade Appsmith to 1.52 or later.
• Follow your normal upgrade process for Appsmith (backup configuration/data as you normally would before a platform upgrade), then apply the update.

Temporary risk reduction (if you can’t upgrade immediately)

• Restrict network access to Appsmith so only trusted IPs/users can reach it (firewall rules, reverse-proxy allowlists, VPN-only access).
• Reduce the number of accounts that can create datasources or execute queries; remove those abilities from users who don’t strictly need them.
• Review Appsmith logs for unusual activity, especially:
  • datasource creation
  • query creation/modification
  • query execution events
  • logins from unexpected IPs or times

What to monitor after upgrading

• Continued datasource/query activity from legitimate users.
• Any errors or repeated attempts around datasource/query operations (which can indicate probing).

Note: This issue is not listed in CISA KEV in the findings you provided.

Severity is effectively critical because the flaw enables remote code execution (commands run inside the Appsmith Docker container). The weakness is consistent with CWE-94 (code injection-like behavior via misconfiguration). The attack vector is network-based and does not require prior authentication to reach the service, but exploitation requires an attacker to gain access through Appsmith workflows: access Appsmith, log in, create a datasource, create a query against that datasource, and execute it. The vendor states a fix is available in appsmith 1.52 (advisory GHSA-m95x-4w54-gc83). No public exploit code is on record in the provided findings, and CISA KEV does not list this CVE.
