Affected: OpenClaw

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.

 https://cve.radiocsirt.org/vuln/ghsa-4qwc-c7g9-4xcw GHSA-4qwc-c7g9-4xcw — OpenClaw: Remote media error responses could trigger unbounded memory allocation before failure 2026-10-04T08:23:51.586478+00:00

Affected: npm: openclaw

## Summary Remote media HTTP error bodies were read without a hard size cap before failure handling, allowing unbounded allocation on error responses.

## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: < 2026.3.22 - Fixed: >= 2026.3.22 - Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`) - Latest published npm version checked: `2026.3.23-2`

## Fix Commit(s) - `81445a901091a5d27ef0b56fceedbe4724566438`

## Release Status The fix shipped in `v2026.3.22` and remains present in `v2026.3.23` and `v2026.3.23-2`.

## Code-Level Confirmation - src/media/fetch.ts now routes non-2xx failures through bounded prefix reads instead of buffering the whole error body. - src/media/read-response-with-limit.ts enforces capped reads and truncates oversized snippets before surfacing failure text.

OpenClaw thanks @YLChen-007 for reporting.
