Security readout for executives and security teams
Plain-English summary
Remarkable is a Markdown renderer. In versions before 1.4.1, certain link input could evade its check for blocked javascript: URLs, letting unsafe links be rendered into content. If an application renders untrusted Markdown to users, this can create browser script-execution risk. The source bundle does not show CISA KEV listing or active exploitation evidence.
Executive priority
Treat this as a targeted web application hygiene issue. Prioritize remediation where public or multi-user systems render untrusted Markdown with vulnerable remarkable versions. It is not KEV-listed in the bundle, but the impact can matter where stored or shared content reaches other users.
Technical view
CVE-2014-10065 affects the HackerOne remarkable node module before 1.4.1. Its bad-protocol filter intended to block javascript: schemes can be bypassed, allowing unsafe URLs in rendered Markdown output. The bundle lists CWE-94, but provides no CVSS score, no CPEs, and limited implementation detail.
Likely exposure
Exposure is most likely in Node.js applications using remarkable below 1.4.1 to render user-controlled or externally supplied Markdown into web pages.
Exploitation context
The available sources describe a sanitization bypass that can enable JavaScript URLs in rendered content. KEV is false, and the bundle provides no evidence of active exploitation. Risk depends on whether rendered Markdown is user-controllable and reachable by other users.
Researcher notes
Evidence is sparse: the CVE record identifies the affected package and version boundary, while references point to the GitHub issue and Node Security advisory. No CVSS vector, CPE mapping, or active exploitation claim is provided. Validate exposure through dependency inventory and Markdown rendering data flow.
Mitigation direction
- Upgrade remarkable to version 1.4.1 or later where used.
- Identify all transitive and direct uses of the remarkable node module.
- Restrict or sanitize user-supplied Markdown before rendering it to browsers.
- Check current vendor guidance if package upgrade is constrained.
- Add regression coverage for blocked URL schemes in rendered Markdown.
Validation and detection
- Review package manifests and lockfiles for remarkable versions below 1.4.1.
- Map routes or services that render Markdown from users or external systems.
- Confirm rendered Markdown does not preserve blocked JavaScript URL schemes.
- Verify dependency scanners flag CVE-2014-10065 in affected builds.
- Confirm tests cover Markdown links and unsafe protocol handling.

Improper Control of Generation of Code ('Code Injection')
Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
