Next 10 actions

Clusters are fingerprinted by normalized selector path + rule id + snippet shape. Rank score = (severity weight × pages affected) / distinct components for the rule. This supersedes the template threshold heuristic while still surfacing it as a validation signal.

Design-system alignment (cms-ds / default). ds-c-field: 100% of sampled rule findings 27 possible lookalike cluster(s) without system prefixes.

Bug reports

⊘ Excluding URLs matching: .aspx. View all pages

17 issue type(s) are shown by default out of 55 total. Prioritized by severity, key pages, WCAG level, and prevalence; use the toggle to show everything.

Overall severity mix: 5 critical, 9 serious, 38 moderate, 3 minor. By WCAG category: 23 WCAG 2.0 A, 6 WCAG 2.0 AA, 1 WCAG 2.2 AA, 4 WCAG 2.x AAA, 11 Best Practice, 10 Undetermined. Ordered by severity, key-page impact, WCAG level, and prevalence. Following accessibility bug-reporting best practices. Download: Markdown · JSON (full archive) · JSON (AI diagnostic) · CSV (all findings) · Priority pages CSV · Priority pages JSON.

Automated testing does not establish full WCAG conformance. Findings in the verification lane require manual testing before they are treated as confirmed failures.

The 50 highest-priority findings are shown in full; 5 more lower-priority finding(s) are summarised at the end of the page, and every finding is in the CSV/JSON downloads.

6 finding(s) marked "possible duplicate" — Alfa and axe-core both flagged the same WCAG SC on overlapping pages. If they target the same element, the axe-core report is authoritative. Filter the CSV by possible_duplicate_of to see these. Two engines flagging the same barrier reduces the chance of a false positive.

Findings needing review

These findings need manual verification before they can be treated as confirmed failures. Obligation remains visible for each finding.

<html>

Description

<html> element must have a lang attribute. Detected by axe-core rule html-has-lang on 146 of 8040 scanned pages (146 instances).

Steps to reproduce

  1. Open https://www.cms.gov/icd10m/version33-fullcode-cms/fullcode_cms/P0099.html.
  2. Locate the element: html
  3. Confirm the axe-core finding for rule html-has-lang against WCAG 3.1.1 Language of Page.

Impact

Affects Without vision (1.0%), Limited cognitive, language, or learning ability (11.0%).

  • Without vision — 1.0% of population
  • Limited cognitive, language, or learning ability — 11.0% of population

Affected pages

…and more — all 146 pages (CSV).

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: Add a lang attribute to <html> (e.g. lang="en").

Drupal tip: Drupal sets the page lang attribute from Admin › Configuration › Regional and Language › Languages. Ensure the default language is configured.

  • Limited manipulation/strength — 13.0% of population

Affected pages

…and more — all 116 pages (CSV).

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: Associate every form control with a <label> (via for/id) or an aria-label/aria-labelledby.

Drupal tip: Use Drupal's form element "Label" setting. In Webform, every element has a Label field — ensure it's not empty or hidden. Check that twig templates don't strip <label> elements from form fields.

  • Without vision — 1.0% of population
  • Limited vision — 2.4% of population
  • Limited cognitive, language, or learning ability — 11.0% of population

Affected pages

…and more — all 32 pages (CSV).

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: Give every <img> a meaningful alt attribute. Use alt="" only for decorative images so screen readers skip them.

Drupal tip: In Drupal's Media Library, fill the "Alternative text" field when uploading or editing an image. For images in body fields, the CKEditor "Image Properties" dialog includes an Alt Text field.

Affected pages

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: Give the link discernible text. Avoid empty links and icon-only links without an aria-label.

Drupal tip: "Read more" links from Drupal Views should use the "Link text" rewrite field to add context, or add aria-label via the Views rewrite output.

<strong>A. General</strong>

Description

Elements must meet minimum color contrast ratio thresholds. Detected by axe-core rule color-contrast on 31 of 8040 scanned pages (430 instances).

Steps to reproduce

  1. Open https://www.cms.gov/medicare-coverage-database/view/ncd.aspx?ncdid=380&ncdver=1.
  2. Locate the element: #lblItemServiceDescription > font > em > p:nth-child(1) > strong
  3. Confirm the axe-core finding for rule color-contrast against WCAG 1.4.3 Contrast (Minimum).

Impact

Affects Limited vision (2.4%), Without color perception (4.5%).

  • Limited vision — 2.4% of population
  • Without color perception — 4.5% of population

Affected pages

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: Increase the contrast between text and its background to at least 4.5:1 (3:1 for large text). Check both light and dark modes.

Drupal tip: Check your Drupal theme's base CSS. Themes like Olivero and Bartik have contrast issues in default color schemes — override failing color pairs in your subtheme's style.css.

Unique accessibility issues (axe + Alfa consolidated)

axe and Alfa both implement W3C ACT rules, so the same issue is often caught by both. These are deduplicated by ACT rule and page, so a shared finding counts once (16785 raw engine findings → 16658 unique).

10 rule type(s) caught by both engines — highest confidence

Two independent ACT-rule implementations (Deque axe-core and Siteimprove Alfa) flagged the same issue on the same pages. Agreement between separate engines is strong evidence the barrier is real, not a single-tool false positive — the best place to start.

Rules flagged by both axe-core and Alfa in 2026-W26, by pages affected.
