Vulnerability details

SES safely executes third-party JavaScript 'strict' mode programs in compartments that have no excess authority in their global scope. Prior to version 1.12.0, web pages and web extensions using `ses` and the Compartment API to evaluate third-party code in an…

isolated execution environment that have also elsewhere used `const`, `let`, and `class` bindings in the top-level scope of a `<script>` tag will have inadvertently revealed these bindings in the lexical scope of third-party code. This issue has been patched in version 1.12.0. Workarounds for this issue involve either avoiding top-level `let`, `const`, or `class` bindings in `<script>` tags, or change these to `var` bindings to be reflected on `globalThis`.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-497

Ongoing reviews detect and remove sensitive system information before it reaches publicly accessible systems.

addresses: CWE-497

Employs detection to prevent unauthorized mining of sensitive system information from being exfiltrated to external control spheres.

addresses: CWE-497

Documenting where system information is processed and stored prevents exposure to unauthorized control spheres.

addresses: CWE-497

The control stops sensitive system information from crossing into unauthorized control spheres through EM emanations.

addresses: CWE-497

Authorization and minimization requirements keep PII out of test/research control spheres that often lack production-grade protections.

addresses: CWE-497

Documented categorization of system information reduces the chance that sensitive internals are left exposed to unauthorized spheres.

addresses: CWE-497

System information is concealed or replaced with decoys, reducing leakage to unauthorized observers.

addresses: CWE-497

Ensures sensitive system information is not disclosed outside the intended control sphere through error output.
