EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 73% 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).

Spacebar Server before commit 8d126f4 contains a cross-channel message deletion vulnerability in the single-delete and bulk-delete message handlers that fail to scope message queries to the requested channel. Authenticated users with MANAGE_MESSAGES permission in any controlled channel can delete arbitrary messages in other channels by routing delete requests through their own channel.
