## Security fix

**High severity:** Overbroad path-parameter regex in generated Ory Oathkeeper access rules could cause an authentication/authorization bypass.

Previously, every OpenAPI `string` path parameter (and any parameter type the generator couldn't classify) was compiled to the unanchored regex token `<.+>`. Because `.` matches `/` in Go's regexp engine — and in Ory Oathkeeper's `regexp` matching strategy — a rule generated for a single path segment (e.g. `/public/{slug}`) also matched deeper, unrelated paths under the same prefix (e.g. `/public/admin/delete-all-users`). If those deeper paths weren't defined as their own, more specific OpenAPI operations, the broader (often unauthenticated `noop`) rule would match and proxy them instead of being rejected.

Generated rules for `string` and unclassified path parameters now use `<[^/]+>`, anchored to a single URL segment, matching the behavior already documented for numeric parameters.

**Action required:** Regenerate your Ory Oathkeeper access rules with this version and redeploy them. Rules generated by earlier versions using `string` path parameters may be broader than intended.
