Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Jerryscript commit cefd391 was discovered to contain a segmentation violation via the component parser_parse_class at jerry-core/parser/js/js-parser-expr.c

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-284

The application fails to correctly restrict what a user can do or reach, so functions or resources are available to people who should not have them. Attackers simply probe for the paths where the check is missing or wrong. The fix is to enforce access-control decisions consistently on every request, evaluated against the acting user rather than assumed from context.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Recommended fix Moderate confidence

Jerryscript 3.1.0 or latest stable release

  1. 1. Identify the current Jerryscript version in your project by checking your dependencies (package.json, requirements, or build configuration)
  2. 2. Navigate to the Jerryscript GitHub repository at https://github.com/jerryscript-project/jerryscript
  3. 3. Check the Releases section to identify the latest stable release after version 3.0.0
  4. 4. Review the release notes or changelog for version 3.1.0 (or latest) to confirm the segmentation fault fix is included
  5. 5. Update your project's dependency to the fixed Jerryscript version (e.g., upgrade to 3.1.0 or latest stable)
  6. 6. Rebuild and test your application to ensure the upgrade does not introduce regressions
  7. 7. Verify the fix resolves the parser_parse_class segmentation issue
Caveat Minor: Review release notes for any API changes or breaking changes between 3.0.0 and the target version

No vendor fix exists Jerryscript has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
