CVE-2026-108698

The hyper-mcp software (versions through 0.8.3 ) contains a TOCTOU (Time-of-Check Time-of-Use) Race Condition vulnerability within the load_wasm function in src/wasm/oci.rs. The root cause is that the system verifies the Cosign signature of a separately resolved tag instead of the actual loaded m...

Hyper-MCP race condition issue

Hyper-MCP versions 0.8.3 and earlier have a vulnerability due to a race condition. This issue arises because the loadwasm function in src/wasm/oci.rs verifies the Cosign signature of individual tags, rather than the signature of the loaded manifests. An attacker can control the registry responses...
