@fedify/fedify is vulnerable to Uncontrolled Resource Consumption
50
Medium Risk
This Affects:
@fedify/fedifyTL;DR
Affected versions of this package consume unbounded memory when activity delivery fails with large HTTP error responses. The sendActivity() function reads the entire response body via response.text() without any size limit and stores it in both the error message and log output. Under production conditions with many unreachable inboxes returning large HTML error pages (50–100 KB each), this leads to significant memory pressure and V8 OOM crashes. The patch limits the SendActivityError.responseBody property to 1 KiB.
