Description
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-4qwc-c7g9-4xcw. This link is maintained to preserve external references.
Original Description
OpenClaw before 2026.3.22 contains an unbounded memory allocation vulnerability in remote media HTTP error handling that allows attackers to trigger excessive memory consumption. Attackers can send crafted HTTP error responses with large bodies to remote media endpoints, causing the application to allocate unbounded memory before failure handling occurs.
Affected versions
npm
| Package | Vulnerable | Fixed in |
|---|---|---|
| openclaw | < 2026.3.22 |
2026.3.22 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
openclaw npm → 2026.3.22
- npm
npm install openclaw@2026.3.22- yarn
yarn add openclaw@2026.3.22- pnpm
pnpm add openclaw@2026.3.22

Weakness
CWE-789: Memory Allocation with Excessive Size Value
The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated.
How to prevent it
- Implementation, Architecture and Design: Perform adequate input validation against any value that influences the amount of memory that is allocated. Define an appropriate strategy for handling requests that exceed the limit, and consider supporting a configuration option so that the administrator can extend the amount of memory to be used if necessary.
- Operation: Run your program using system-provided resource limits for memory. This might still cause the program to crash or exit, but the impact to the rest of the system will be minimized.
