The PHP security advisories StackDrift reads stop listing a release once it reaches end of life, and do not reach back far enough to cover every older one, so PHP 7.3 is not fully checked against them. An empty list here is not a clean result.
A further 1 advisories publish no version range, so whether they reach 7.3 cannot be determined from the advisory alone.
Where to move next
The newest tracked release is 8.5.12. If moving release is not an option yet, 7.3.33 is the newest build on the 7.3 line and needs no migration.
