• CVE-2026-61807: 0.21% estimated exploitation activity in the next 30 days; percentile 11.58 (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.

Impact The table component derives data-selected-count-id from the component $name value. On manufacturer and supplier detail pages, stored manufacturer or supplier names are passed into affected table components as that name value. The client-side JavaScript later reads the browser-decoded data-selected-count-id, uses it as a selector, and concatenates countId.substring(1) directly into an HTML string passed to jQuery .after(). Affected commit: b224cc636c6780386e3f73f03d1171f52ab4c37a Example payload for a manufacturer or supplier name: x[foo="<svg/onload=alert(1)"] The issue appears to involve the following flow: Stored supplier/manufacturer name - table component data-selected-count-id - browser decodes the attribute - JavaScript reads countId - countId is used as a selector - countId.substring(1) is concatenated into HTML - jQuery .after() inserts attacker-controlled markup - JavaScript executes in the victim's browser Potential impact includes arbitrary JavaScript execution in…

# Patch Next advisory brief: CVE-2026-61807

Advisory: Snipe-IT: Stored DOM XSS via table selected-count IDs
IDs: CVE-2026-61807, GHSA-c8qc-wf67-342w
Record: https://patchnext.com/advisories/cve-2026-61807 (revision 1, source checked 26 Oct 2026, 14:50 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: snipe/snipe-it 8.6.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist snipe/snipe-it: affected < 8.6.2; fixed in 8.6.2

## Suggested inspection (read-only)
- Packagist snipe/snipe-it: check the installed version with your package manager.

## 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 snipe/snipe-it.
- 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://github.com/advisories/GHSA-c8qc-wf67-342w (GitHub-reviewed advisory GHSA-c8qc-wf67-342w lists affected ranges: Packagist snipe/snipe-it >=0 <8.6.2)
