CVE-2026-56851

Summary

The vulnerability is an out-of-bounds slice error in the Nickname profile transformation logic that can cause a panic when processing crafted input into a short destination buffer. This allows an attacker to trigger a denial of service condition without requiring authentication or user interaction.

Exploitability

Exploitation is moderately difficult as it requires crafting specific input that triggers the out-of-bounds slice error, but does not require authentication or complex preconditions.

Blast radius

The impact is limited to causing a panic and denial of service for the affected service, with no data exposure or persistence, though multiple concurrent attacks could potentially overwhelm the system.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

No fixed version is published. Disable the Nickname profile transformation feature until a patch is available.
