CVE-2025-66027
Prior to version 4.5.6, an information disclosure vulnerability exposes participant details, including names and email addresses through the /api/trpc/polls.get,polls.participants.list endpoint, even when Pro privacy features are enabled.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Rallly is an open-source scheduling and collaboration tool. Prior to version 4.5.6, an information disclosure vulnerability exposes participant details, including names and email addresses through the /api/trpc/polls.get,polls.participants.list endpoint, even when Pro privacy features are enabled. This bypasses intended privacy controls that should prevent participants from viewing other users’ personal information. This issue has been patched in version 4.5.6.
