CVE-2026-77167

Abusing the federated share endpoint, an attacker can write arbitrary rows into the ocshareexternal database table. These rows persist indefinitely — there is no automatic cleanup mechanism. Three distinct denial-of-service conditions follow from this write primitive, all triggered from the same unauthenticated source and all self-renewing on a 24-hour cycle for as long as the injected rows remain in the database.
