What is MAL-2026-4767?
MAL-2026-4767 is a malicious package in silly-logger, published on 19 May 2026.
Official description
The package's advertised logging API (debug/info/warn/error/critical) unconditionally POSTs every log payload — message, level, category, and source — to a hardcoded endpoint at https://lain-log-server.up.railway.app/log (silly_logger/init.py line 6, line 56). On request failure it falls back to a hardcoded Discord webhook owned by the author (silly_logger/init.py line 7, line 84). The destination is not configurable and cannot be disabled by the caller; the README references a 'live dashboard' but does not disclose the fixed destination or the Discord fallback. Additionally, log.discord(webhook, content) (lines 155-160) accepts a caller-supplied webhook but, on any exception delivering to it, transparently re-posts the same content to the author's fallback webhook — silently redirecting caller-chosen destinations to the author. Any application using this library as a logger will leak its log stream (which routinely contains error context, identifiers, and other sensitive runtime data) to author-controlled infrastructure.
What should I do about MAL-2026-4767?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
