Source description

As published by the source; long descriptions are shortened.

LavaLite CMS versions up to and including 10.1.0 contain a stored cross-site scripting vulnerability in the package creation and search functionality. Authenticated users can supply crafted HTML or JavaScript in the package Name or Description fields that is stored and later rendered without proper output encoding in package search results. When other users view search results that include the malicious package, the injected script executes in their browsers, potentially enabling session hijacking, credential theft, and unauthorized actions in the context of the victim.

# Patch Next advisory brief: CVE-2025-71177

Advisory: LavaLite CMS affected by a stored cross-site scripting vulnerability
IDs: CVE-2025-71177, GHSA-w7rq-fgx4-4xcm
Record: https://patchnext.com/advisories/cve-2025-71177 (revision 1, source checked 26 Oct 2026, 14:35 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist lavalite/cms: affected <= 10.1.0

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

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on lavalite/cms.
- 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.
