OpenClaw's inbound media downloads could exceed configured byte limits before rejection across multiple channels

## Summary OpenClaw did not consistently enforce configured inbound media byte limits before buffering remote media in several channel ingestion paths. A remote sender could trigger oversized downloads and memory pressure before rejection. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `<= 2026.2.21-2` (latest published at triage time) - Fixed in: `2026.2.22` (planned next release) ## Impact An attacker could cause elevated memory usage and potential process instability (denial of service) by sending oversized media payloads. ## Fix Commit(s) - `73d93dee64127a26f1acd09d0403b794cdeb4f5c` ## Release Process Note `patched_versions` is pre-set to the planned next release (`2026.2.22`). After that npm release is published, this advisory can be published without further version-field edits. OpenClaw thanks @tdjackey for reporting.
