What
Claude Code has a check that flags web addresses whose real destination may differ from what they appear to be. It already rejected addresses containing a null character. It now rejects another kind of address at the same early stage, before it compares the site names. The rest of the check is unchanged.
Why
This may make the check stricter about which web addresses it lets through.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
It is not clear what kind of address the new early test catches.
