RansomLook fails to enforce the privacy status of ransomware groups and markets when distributing newly collected victim posts to external notification channels.
Overview
CVE-2026-78380 is a known-severity vulnerability. It was published on August 24, 2026.
Technical description
RansomLook fails to enforce the privacy status of ransomware groups and markets when distributing newly collected victim posts to external notification channels. The post-processing logic checks whether an individual post is marked private but does not verify whether the group or market to which the post belongs is configured as private.
As a result, newly parsed victim information associated with a private group or market may be automatically published through enabled Rocket.Chat, Mastodon, Bluesky, and e-mail notification channels despite the entity being explicitly configured to prevent public disclosure.
A similar issue affects the public MISP feed. The feed previously determined privacy using groupinfo(), which only queries the group database. Consequently, victim information associated with private markets could be added to the public MISP feed because the corresponding market privacy flag was not evaluated.
An attacker or other unauthorized party able to access these public n
