No CVSS score has been assigned to CVE-2025-14284 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-14284?

CVE-2025-14284 affects the following packages: @tiptap/extension-link (npm). Ecosystems affected: npm.

How do I fix CVE-2025-14284?

Update @tiptap/extension-link to 2.10.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-14284 is resolved across your whole dependency graph.

How do I detect CVE-2025-14284 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @tiptap/extension-link, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2025-14284 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2025-14284?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-14284 can be triaged on real exposure rather than presence alone.

Is CVE-2025-14284 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-14284 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-14284?

CVE-2025-14284 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 31th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2025-14284?

CVE-2025-14284 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2025-14284 published, and has it been updated?

CVE-2025-14284 was published on December 9, 2025 and was last updated on August 12, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Versions of the package @tiptap/extension-link before 2.10.4 are vulnerable to Cross-site Scripting (XSS) due to unsanitized user input allowed in setting or toggling links. An attacker can execute arbitrary JavaScript code in the context of the application by injecting a javascript: URL payload into these attributes, which is then triggered either by user interaction.
