Element Plus Link component (el-link) implements insufficient input validation for the href attribute
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

element-plusnpmDescription
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for element-plus, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of element-plus has shipped for GHSA-5m5x-9j46-h678 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-5m5x-9j46-h678 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-5m5x-9j46-h678. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
