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). No design-system components detected in sampled findings.

Bug reports

13 issue type(s) are shown by default out of 40 total. Prioritized by severity, key pages, WCAG level, and prevalence; use the toggle to show everything.

Overall severity mix: 2 critical, 8 serious, 27 moderate, 3 minor. By WCAG category: 14 WCAG 2.0 A, 4 WCAG 2.0 AA, 1 WCAG 2.2 AA, 2 WCAG 2.x AAA, 11 Best Practice, 8 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.

Default view shows 13 prioritized issue type(s); 27 more are available if you switch to "Show everything".

1 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.

<img src="cms-site-logo.png">

Description

Images must have alternative text. Detected by axe-core rule image-alt on 273 of 8304 scanned pages (273 instances).

Steps to reproduce

  1. Open https://www.cms.gov/icd10m/version35-fullcode-cms/fullcode_cms/P0009.html.
  2. Locate the element: img[src$="cms-site-logo.png"]
  3. Confirm the axe-core finding for rule image-alt against WCAG 1.1.1 Non-text Content.

Impact

Affects Without vision (1.0%), Limited vision (2.4%), Limited cognitive, language, or learning ability (11.0%).

  • 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 273 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

…and more — all 273 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.

Description

Elements must meet minimum color contrast ratio thresholds. Detected by axe-core rule color-contrast on 107 of 8304 scanned pages (643 instances).

Steps to reproduce

  1. Open https://www.cms.gov/medicare-coverage-database/view/article.aspx?articleid=52516&articleStatus=all&bc=3&sortBy=title&ver=26.
  2. Locate the element: tr:nth-child(1) > td[width="50%"] > p

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.

Description

Landmarks should have a unique role or role/label/title (i.e. accessible name) c. Detected by axe-core rule landmark-unique on 2 of 8304 scanned pages (2 instances).

Steps to reproduce

  1. Open https://www.cms.gov/priorities/health-equity/minority-health/resource-center/webinars-trainings/coverage-care-c2c-webinars.
  2. Locate the element: .ds-u-lg-padding--0.ds-u-margin-y--2.ds-u-lg-margin-y--4:nth-child(8) > .ds-u-lg-padding-right--2.ds-l-lg-col--4.ds-u-padding-x--0 > div[role="region"]
  3. Confirm the axe-core finding for rule landmark-unique.

Impact

Not captured by automated scan — requires manual testing.

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: When a landmark role/type repeats (e.g. two <nav>s), give each a distinct accessible name with aria-label or aria-labelledby (e.g. "Primary" and "Footer" navigation) so screen-reader users can tell them apart.

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 (19320 raw engine findings → 19025 unique).

5 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-W25, by pages affected.
