CVE-2026-108730
Raven 2.0.0 through 3.0.0 contains a missing authorization vulnerability in legacy methods in raven/api/raven_message.py that skip the workspace membership check. Authenticated non-members can call get_messages_with_dates or get_all_files_shared_in_channel with predictable channel IDs to read Public channel history and Open/Public channel file metadata across workspaces.
CVSS
- Version: 4.0

- Base score: 5.3
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.25%
- Percentile among all scored CVEs: 15
- Score date: 10/14/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
