devbridge-autocomplete has XSS in its default formatters: formatGroup and formatResult fail to escape HTML in untrusted inputs

GHSA-hvqh-jw65-wcpq

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (devbridge-autocomplete 2.0.1), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Summary The default formatGroup and formatResult functions in devbridge-autocomplete concatenate values into HTML without escaping, allowing XSS when an attacker controls (or can taint) the suggestion data source. Details 1. formatGroup — category is interpolated raw. src/format.ts: If groupBy is used and the grouping field of any suggestion contains HTML, that HTML is executed. 2. formatResult — early-return branch returns suggestion.value raw. src/format.ts: The early-return branch is reached when suggest() renders with an empty currentValue, which happens with minChars: 0 and a server that returns suggestions for an empty query. The returned string is concatenated into the container's innerHTML. PoC (formatGroup) Originally identified by an earlier human analysis; the PoC above was produced with the assistance of Claude Opus 4.7. Impact XSS in pages that render attacker-controllable suggestion data. The actual impact depends on what the embedding page has access to (cookies,…

# Patch Next advisory brief: GHSA-hvqh-jw65-wcpq

Advisory: devbridge-autocomplete has XSS in its default formatters: formatGroup and formatResult fail to escape HTML in untrusted inputs
IDs: GHSA-hvqh-jw65-wcpq
Record: https://patchnext.com/advisories/ghsa-hvqh-jw65-wcpq (revision 2, source checked 26 Oct 2026, 12:56 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: devbridge-autocomplete 2.0.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm devbridge-autocomplete: affected <= 2.0.0; fixed in 2.0.1

## Suggested inspection (read-only)
- `npm ls devbridge-autocomplete --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## 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 devbridge-autocomplete.
- 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-hvqh-jw65-wcpq (OSV record GHSA-hvqh-jw65-wcpq lists affected ranges: npm devbridge-autocomplete >=0 <2.0.1 (fixed))
- Verified: https://github.com/advisories/GHSA-hvqh-jw65-wcpq (GitHub-reviewed advisory GHSA-hvqh-jw65-wcpq lists affected ranges: npm devbridge-autocomplete >=0 <=2.0.0)
