CVE-2022-21707 Detail

Current Description

wasmCloud Host Runtime is a server process that securely hosts and provides dispatch for web assembly (WASM) actors and capability providers. In versions prior to 0.52.2 actors can bypass capability authorization. Actors are normally required to declare their capabilities for inbound invocations, but with this vulnerability actor capability claims are not verified upon receiving invocations. This compromises the security model for actors as they can receive unauthorized invocations from linked capability providers. The problem has been patched in versions `0.52.2` and greater. There is no workaround and users are advised to upgrade to an unaffected version as soon as possible.

Base Score:  6.3 MEDIUM
Vector:  CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
