• CVE-2025-62172: 0.43% estimated exploitation activity in the next 30 days; percentile 37.53 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary An authenticated party can add a malicious name to the Energy entity, allowing for Cross-Site Scripting attacks against anyone who can see the Energy dashboard, when they hover over any information point (The blue bar in the picture below) <img width="955" height="568" alt="1cens" src="https://github.com/user-attachments/assets/ed855216-c306-4b50-affc-cda100e72b74" / An alternative, and more impactful scenario, is that the entity gets a malicious name from the provider of the Entity (in this case the energy provider: Tibber), and gets exploited that way, through the default name. Details The incriminating entity in my scenario is from the Tibber integration, as shown in the screenshot below: <img width="822" height="309" alt="2cens" src="https://github.com/user-attachments/assets/d0d5a7aa-8d0c-4dcb-825b-e4cb8ea8885b" / The exploit should be possible regardless of the Energy integration, as the user can name the entity themselves and as such pick a malicious name.

# Patch Next advisory brief: CVE-2025-62172

Advisory: Home Assistant has Stored XSS vulnerability in Energy dashboard from Energy Entity Name
IDs: CVE-2025-62172, GHSA-mq77-rv97-285m
Record: https://patchnext.com/advisories/cve-2025-62172 (revision 3, source checked 26 Oct 2026, 13:37 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: homeassistant 2025.10.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI homeassistant: affected >= 2025.1.0, <= 2025.10.1; fixed in 2025.10.2

## Suggested inspection (read-only)
- `python -m pip show homeassistant`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on homeassistant.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-mq77-rv97-285m (OSV record GHSA-mq77-rv97-285m lists affected ranges: PyPI homeassistant >=2025.1.0 <2025.10.2 (fixed))
- Verified: https://github.com/advisories/GHSA-mq77-rv97-285m (GitHub-reviewed advisory GHSA-mq77-rv97-285m lists affected ranges: PyPI homeassistant >=2025.1.0 <=2025.10.1)
