http4k: BasicCookieStorage` (renamed `InsecureCookieStorage`) did not enforce RFC 6265 cookie scoping; new `DefaultCookieStorage` is now the default
Impact
The previous BasicCookieStorage did not enforce RFC 6265 scoping rules around cookie domain, path, and Secure attribute. A client using a single storage instance to talk to multiple origins could have cookies leak across domains, or have Secure cookies sent over plain HTTP — the deprecation message states it bluntly: "BasicCookieStorage has no domain/path/scheme scoping and leaks cookies across origins. Use DefaultCookieStorage instead."
Who is affected: any client using BasicCookieStorage directly with cookies for more than one origin or scheme. Single-origin uses are unaffected.
Patches
| Line | Fixed in | Edition |
|---|---|---|
| v6.x (Community) | 6.48.0.0 | Community |
| v5.x (LTS) | 5.42.0.0 | Enterprise — contact enterprise@http4k.org |
| v4.x (LTS) | 4.51.0.0 | Enterprise — contact enterprise@http4k.org |
The fix introduces DefaultCookieStorage (RFC 6265 compliant) as the drop-in default; BasicCookieStorage is renamed InsecureCookieStorage and remains available for callers with a deliberate need for the old behaviour.
Workarounds
For deployments that cannot upgrade immediately:
- Use a dedicated
BasicCookieStorageinstance per origin / scheme, or - Switch to a separate RFC 6265-compliant cookie store implementation.
