Summary

Gateway plugin route auth protection for /api/channels could be bypassed using encoded dot-segment traversal (for example ..%2f) in path variants that plugin handlers normalize.

Affected Packages / Versions

  • Vulnerable version range: <= 2026.2.25
  • Patched version: 2026.2.26 (planned next release)

Impact

Under affected versions, crafted alternate paths could bypass gateway auth checks for protected plugin channel routes when plugin handlers decode/canonicalize the incoming path and then route to /api/channels/... handlers.
