See the response matrix section in the security advisory you raised ie https://www.vmware.com/security/advisories/VMSA-2023-0014.html
For ease of reference i have copied the table below. The wording may not be entirely clear, but affected versions are show in the "Running On" column. Note the 2 entries circled state "Any" version, and the Fixed version is 7.0U3m. Therefore ALL builds prior to 7.0U3m are affected.
You quoted vCenter version 7.0.2 build 17958471. From the vCenter builds page linked below, this maps to 7.0 Update 2b (hence=affected). The second build you quoted (7.0.3 build 21686933) is an ESXi build, and is therefore not relevant to this advisory.
