• CVE-2025-57665: 0.24% estimated exploitation activity in the next 30 days; percentile 14.69 (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.

Element Plus Link component (el-link) prior to 2.11.0 implements insufficient input validation for the href attribute, creating a security abstraction gap that obscures URL-based attack vectors. The component passes user-controlled href values directly to underlying anchor elements without protocol validation, URL sanitization, or security headers. This allows attackers to inject malicious URLs using dangerous protocols (javascript:, data:, file:) or redirect users to external malicious sites. While native HTML anchor elements present similar risks, UI component libraries bear additional responsibility for implementing security safeguards and providing clear risk documentation. The vulnerability enables XSS attacks, phishing campaigns, and open redirect exploits affecting applications that use Element Plus Link components with user-controlled or untrusted URL inputs. As of version 2.11.0, Element Plus have clearly documented the risks inherent with the component.

# Patch Next advisory brief: CVE-2025-57665

Advisory: Element Plus Link component (el-link) implements insufficient input validation for the href attribute
IDs: CVE-2025-57665, GHSA-5m5x-9j46-h678
Record: https://patchnext.com/advisories/cve-2025-57665 (revision 3, source checked 26 Oct 2026, 12:37 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.6)
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
- npm element-plus: affected <= 2.11.0

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

## 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 element-plus.
- 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
