📝 Walkthrough

Walkthrough

The pull request adds URL validation across navigation components, restricts modal property application, fixes reserved tree IDs, preserves spaces in category-filter input, hardens workflow permissions, improves identifier randomness, and updates documentation serialization.

Changes

Navigation and component security

Layer / File(s) Summary
Safe navigation contract and integrations
packages/core/src/components/utils/condition-checks.ts, packages/core/src/components/{application-header,breadcrumb-item,button,link-button,menu-item}/..., packages/core/src/components.d.ts, packages/core/src/components/utils/application-layout/context.ts, .changeset/secure-*.md
Navigation URLs now allow relative, HTTP(S), mailto, and tel destinations. Unsafe URLs are omitted. Application switches use noopener.
Explicit modal configuration
packages/core/src/components/utils/modal/{modal,message}.ts, packages/core/src/components/modal/test/modal.ct.ts, .changeset/secure-modal-configuration.md
Modal helpers apply documented options explicitly and do not copy arbitrary properties onto modal elements.
Reserved tree item contexts
packages/core/src/components/tree/tree.tsx, packages/core/src/components/tree/test/tree.ct.ts, .changeset/secure-tree-item-ids.md
Tree context creation uses own-property checks and supports reserved item IDs without prototype pollution.

Component behavior fixes

Layer / File(s) Summary
Category-filter keyboard behavior
packages/core/src/components/category-filter/category-filter.tsx, packages/core/src/components/category-filter/test/category-filter.ct.ts, packages/storybook-docs/src/stories/category-filter.stories.tsx, .changeset/category-filter-space-input.md
Dropdown activation is limited to arrow keys and item selection to Enter. Tests and stories cover spaces in filter input values.
Secure generated identifiers
packages/core/src/components/utils/uuid.ts, .changeset/fix-input-generated-id-randomness.md
Fallback identifiers now use crypto.randomUUID().

Automation and documentation

Layer / File(s) Summary
Workflow permissions and pinned actions
.github/workflows/{build,pr,release,stale}.yml, .changeset/config.json
Workflows use read-only permissions, disable persisted checkout credentials, pin selected actions, install npm 11.8.0 exactly, and resolve changesets from release-5.2.2.
Documentation tag serialization
packages/documentation/scripts/typedoc-generator.ts, packages/documentation/scripts/utils/docs-tags.ts
Documentation tags now serialize escaped markdown for JSX expressions.

Estimated code review effort: 4 (Complex) | ~45 minutes

Severity of issue fixed: High

Merge Risk: 🟡 Moderate · up to 8a4e9

This hardening change improves navigation, modal, tree, and input behavior, but release baseline configuration, insecure-context fallback ID generation, and likely validation failures should be resolved before merging to avoid broken release processing, affected HTTP consumers, or failing checks.

setting noopener discards the target name and always opens a fresh _blank context. AppSwitchConfigurationTarget allows _self, _parent, _top, and arbitrary window names — the new test in this PR uses target: 'reports'.

So an app configured with _self now spawns a new window instead of navigating the current one. Could we apply noopener only when the target is _blank or a custom name?

This branches on the raw props.href, so a rejected URL renders with no href: focusable, announced as a button, inert on Enter. Branching on the sanitized href from line 102 would fall back to a real instead.

Same as base-button: branching on the raw this.href leaves a focusable anchor with no href when the URL is rejected. Using the sanitized href from line 318 would fall back to the branch.

The raw URL is still surfaced as the tooltip, so a blocked javascript:… string stays visible to users even though href was dropped. Combined with the hardcoded tabindex="0" on the next line, this leaves a focusable link that does nothing.

Two small things: Object.create(null) would make the map immune by construction rather than relying on the hasOwnProperty guard below. And context is @prop({ mutable: true }), so when a consumer passes null this now assigns a prop during render() — the previous code returned a throwaway object instead.
