## Summary In OpenClaw MSTeams media download flows, redirect handling could bypass configured `mediaAllowHosts` checks in specific attachment paths. Redirect chains were not consistently constrained to allowlisted targets before accepting fetched content. ## 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 Attackers able to supply or influence attachment URLs could force redirect chains to non-allowlisted targets, weakening SSRF boundary controls for MSTeams media ingestion. ## Fix Commit(s) - `73d93dee64127a26f1acd09d0403b794cdeb4f5c` - `b34097f62df9d1960cc22600269cd3f3284e2124` ## Release Process Note `patched_versions` is pre-set to the planned next release (`2026.2.22`). Once that npm release is published, this advisory can be published without further version-field edits. OpenClaw thanks @tdjackey for reporting.
