Description
Name constraints for URI names were incorrectly accepted
| Details | |
|---|---|
| Package | rustls-webpki |
| Version | 0.101.7 |
| Date | 2026-04-14 |
| Patched versions | >=0.103.12, <0.104.0-alpha.1,>=0.104.0-alpha.6 |
Name constraints for URI names were ignored and therefore accepted.
Note this library does not provide an API for asserting URI names, and URI name constraints are otherwise not implemented. URI name constraints are now rejected unconditionally.
Since name constraints are restrictions on otherwise properly-issued certificates, this bug is reachable only after signature verification and requires misissuance to exploit.
This vulnerability is identified as GHSA-965h-392x-2mh5. Thank you to @1seal for the report.
See advisory page for additional details.

Research direction
Start by checking whether this repository uses rustls-webpki 0.101.7 or another affected version. Compare the dependency with the patched versions listed in the advisory and determine how this repository tracks security updates. Done means the repository's dependency state no longer exposes the affected version, with any applicable existing checks passing.
