Runtime email configuration src/assets/env.js, src/assets/env.template.js, src/environments/environment.ts, src/environments/environment.prod.ts |
Runtime configuration exposes externalEmailRegex. Valid overrides are used. Empty or invalid overrides use a default pattern that rejects empty domain labels. |
Client email validation and feedback src/app/clients/client-stepper/client-general-step/client-general-step.component.ts, src/app/clients/client-stepper/client-general-step/client-general-step.component.html, src/app/clients/client-stepper/client-general-step/client-general-step.component.spec.ts |
The client form validates email values with the resolved pattern. The template displays the pattern validation message. Tests cover blank, valid, malformed, and double-dot domain values. |
Email validation documentation README.md |
The README documents EXTERNAL_EMAIL_REGEX, its default pattern, invalid-regex fallback, and optional email validation. |
Priority: ➖ Normal
Estimated code review effort: 2 (Simple) | ~10 minutes
Change: Bug fix · Severity of issue fixed: Medium
Suggested reviewers: adamsaghy, shubhamkumar9199
Merge Risk: 🟡 Moderate · up to 0c4a0
A valid but expensive deployment regex can make the Create Client email field unresponsive while users type. Constrain override patterns before merging.

…rride Two CodeRabbit findings on openMF#4008: - The default pattern's domain class ([a-zA-Z0-9.-]+) let a literal dot inside it absorb an empty label, so client@example..com passed. Domain labels can no longer contain dots, closing that gap. - A malformed EXTERNAL_EMAIL_REGEX override (e.g. an unbalanced `[`) reached Validators.pattern unvalidated and would throw while building the Create Client form, blocking client creation entirely. Both environment files now validate the override compiles as a RegExp before using it, falling back to the default otherwise.

- Around line 23-39: Replace the compile-only check in isValidRegex with
validation that accepts only a safe, bounded email-pattern format and rejects
potentially catastrophic expressions such as nested quantifiers before
resolvedEmailRegex is selected. Apply the same restriction in both environment
resolvers, preserving DEFAULT_EMAIL_REGEX as the fallback, and update the
documented EXTERNAL_EMAIL_REGEX contract to describe the allowed format and
safety limits.

…ble regex The Create Client General Step used Angular's built-in Validators.email, which accepts loosely formatted addresses, and its error message used a flat 'error.Email not valid' key instead of the app's errors.validation.* namespace already used by the Edit Client form. Replace it with Validators.pattern against a new externalEmailRegex environment setting (default: a stricter RFC-like pattern), mirroring the existing externalNationalIdRegex convention so deployments can override the pattern via env var. The field stays optional: Angular's pattern validator skips empty values. Domain labels in the default pattern cannot contain dots, so client@example..com is rejected. Both environment files validate that an EXTERNAL_EMAIL_REGEX override compiles as a RegExp before using it, falling back to the default so a malformed override cannot throw while building the Create Client form. Supersedes openMF#3180, closed stale.
