* chore: set next hub version to hub-0-15-0 * fix(flame-hub): make the client-ui session cookie domain opt-in
Release-As: v1.0.0
📝 WalkthroughWalkthroughThe chart adds cookie-domain validation for the Hub UI, emits an explicit cookie-domain environment value, updates the Hub image tag and configuration documentation, and removes two release configuration options. ChangesFlame Hub cookie-domain configuration
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The chart’s cookie-domain safeguard can be bypassed when hostnames differ only by letter case, potentially causing session-cookie conflicts between the Hub and Authup interfaces. The change is otherwise mergeable with explicit owner awareness and follow-up to normalize hostnames before comparison. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

RFC 6265 cookie domain matching lower case canonicalization domain-match section 5.1.3
💡 Result:
In RFC 6265, Section 5.1.3 explicitly defines the domain-matching algorithm [1][2]. The specification mandates that for the purpose of domain matching, both the domain string provided in the cookie and the request host string must be canonicalized to lower case [1][3]. Specifically, the algorithm states that a string domain-matches a given domain string if either of the following conditions is met: 1. The domain string and the string are identical (with both having been canonicalized to lower case at this point) [1][2]. 2. All of the following conditions hold: - The domain string is a suffix of the string [1][4]. - The last character of the string that is not included in the domain string is a %x2E (".") character [1][3]. - The string is a host name, not an IP address [1][4]. The requirement to convert to lower case ensures that domain comparisons are performed in a case-insensitive manner, consistent with the standard behavior for domain names on the internet [2][5].

Normalize host names before comparing them.
The case-sensitive eq and hasSuffix checks can miss equivalent DNS names. For example, clientUI.cookieDomain: example.com and authup.server.publicUrl: https://AUTH.EXAMPLE.COM/auth bypass the guard even though RFC 6265 cookie-domain matching is case-insensitive. Lowercase both host names before comparison.

🟡 Changes recommended
The new cookie-domain validation can silently skip checks when authup’s public URL is unparsable (e.g., missing scheme), so it should fail fast to ensure the safeguard is reliable.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
This PR prepares the Flame Hub chart for the v1.0.0 release by updating the Hub image version and tightening/clarifying cookie-domain handling to avoid session-cookie collisions between the Hub UI and authup.
Changes:
- Bump
privateaim/hubimage tag to0.15.0. - Default
NUXT_PUBLIC_COOKIE_DOMAINto an empty value (host-only cookies) unless explicitly set by the operator. - Add a Helm render-time validation that fails if
clientUI.cookieDomainwould cover authup’s host.
