DescriptionCVE.org

Rallly before 4.15.0 contains an information disclosure vulnerability in the polls.get tRPC procedure that returns scheduled-event invitee names and email addresses to unauthenticated callers. Attackers can access a poll's urlId from public invite links to retrieve sensitive invitee information regardless of privacy settings.

AnalysisAI

Unauthenticated information disclosure in Rallly before 4.15.0 allows remote attackers who possess a poll's urlId to retrieve the names and email addresses of scheduled-event invitees through the polls.get tRPC procedure, regardless of the poll's privacy settings. The urlId is embedded in the public invite links Rallly generates and shares, so no credentials, user interaction, or non-default configuration are needed; CVSS 3.1 rates this 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N). …

Vulnerability AssessmentAI

Exploitation Exploitation requires only that the attacker possess a valid poll urlId, which is exposed in the public invite links Rallly generates and shares; no authentication, user interaction, or non-default configuration is needed (unauthenticated remote call to the polls.get tRPC procedure in Rallly before 4.15.0). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine but modest-severity information disclosure issue, and the signals are internally consistent. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade to Rallly 4.15.0 or later; this is the vendor-released patch and the version in which the invitations select and the attendees mapping were removed from the polls.get response (see the release at https://github.com/lukevella/rallly/releases/tag/v4.15.0 and the fix in PR https://github.com/lukevella/rallly/pull/3247, commit 0db11a2cd9e48656d08773e4be6de0e7df584a00). … Detailed patch versions, workarounds, and compensating controls in full report.
