Rallly is an open-source scheduling and collaboration tool. Prior to version 4.5.4, an Insecure Direct Object Reference (IDOR) vulnerability exists in the poll finalization feature of the application. Any authenticated user can finalize a poll they do not own by manipulating the pollId parameter in the request. This allows unauthorized users to finalize other users’ polls and convert them into events without proper authorization checks, potentially disrupting user workflows and causing data integrity and availability issues. This issue has been patched in version 4.5.4.

CRITICALPre-NVD 9.19.1—Elevated
EchelonGraph scoreMEDIUM confidence
This critical-severity CVE scores 9.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 70% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
