CVE-2026-78372
RansomLook does not consistently enforce authorization checks when accessing groups, markets, and ransom notes marked as private.
Overview
CVE-2026-78372 is a known-severity vulnerability. It was published on August 24, 2026.
Technical description
RansomLook does not consistently
enforce authorization checks when accessing groups, markets, and ransom
notes marked as private. An unauthenticated or otherwise unauthorized
remote attacker can access information associated with private entities
through several web views and API endpoints.
The affected functionality can
disclose private group or market names, ransom-note content, and
metadata associated with private groups. The /compare
functionality can also be queried directly with the name of a private
entity, allowing an unauthorized user to retrieve information such as
post counts, mirror totals, and uptime even when the entity is excluded
from the normal user interface. The patch explicitly adds a privacy
check before returning this information.
Ransom-note views, search results,
and API endpoints were similarly missing consistent filtering. The fix
introduces normalized private-group identifiers and alias handling, then
rejects or filters notes associated wit
