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

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.
