CVE-2026-26055 affects Yoke versions 0.19.0 and earlier, a Helm-inspired infrastructure-as-code deployer, due to missing authentication in the Air Traffic Controller (ATC) component's webhook endpoints.

Rated 7.5 HIGH, the vulnerability has a network attack vector and low complexity, enabling an unauthenticated attacker to trigger WASM module execution with high integrity impact. Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed on the CISA KEV catalog.
