History
When vindicators were introduced in 16w39a, their iron axe was purely visual, so their base damage (on normal difficulty) was set to a reasonable value of 2.5 hearts.
In the next snapshot, the axe became a real item, so its damage of +4 hearts was added to the vindicator’s damage output. The mob’s base damage was not lowered to compensate. This unintentionally made vindicators deal a total of 6.5 hearts of damage.
This change was not mentioned in the changelog, so it appears to have been an oversight. Contrast with vexes, who have always used a real weapon, and whose +2 heart damage buff in 16w42a, insane as it was, was in the changelog.
Unlike the similar issue with zombie pigmen (MC-305896), I don’t believe the original 2.5 hearts of damage vindicators dealt should be considered the intended amount, since that’s less than an iron axe deals, and it was changed after a single snapshot. However, I do believe that adding the damage of an axe to the mob without adjusting its base damage was an oversight. It’s unclear what the intended amount is, but following the example of pigmen, an additional 0.5 hearts on top of the weapon damage seems reasonable.

I tested this in 1.21.11 and 26.1 Snapshot 4 and observed the same behavior in both versions.
On Normal difficulty, Vindicators consistently dealt 6.5 hearts of damage, matching the current behavior described in the report.
To further compare weapon damage behavior, I also tested mobs holding equivalent weapons in 1.21.11:
A zombie holding a golden sword on normal difficulty dealt 5.5 hearts of damage
A player holding a golden sword on normal difficulty (non-critical hit) deals 4.5 hearts of damage
This matches what’s described above.
Below is a video of my results of this issue as well as MC-305896 since they appear to involve similar damage behavior.
