@fastly/js-compute is a JavaScript SDK and runtime for building Fastly Compute applications. The implementation of several functions were determined to include a use-after-free bug. This bug could allow for unintended data loss if the result of the preceding functions were sent anywhere else, and often results in a guest trap causing services to return a 500. This bug has been fixed in version 3.16.0 of the `@fastly/js-compute` package.

 https://cve.radiocsirt.org/vuln/ghsa-mp3g-vpm9-9vqv GHSA-mp3g-vpm9-9vqv — @fastly/js-compute has a use-after-free in some host call implementations 2026-10-05T21:24:38.879769+00:00

Affected: npm: @fastly/js-compute

### Impact The implementation of the following functions were determined to include a use-after-free bug:

* `FetchEvent.client.tlsCipherOpensslName` * `FetchEvent.client.tlsProtocol` * `FetchEvent.client.tlsClientCertificate` * `FetchEvent.client.tlsJA3MD5` * `FetchEvent.client.tlsClientHello` * `CacheEntry.prototype.userMetadata` of the `fastly:cache` subsystem * `Device.lookup` of the `fastly:device` subsystem

This bug could allow for an unintended data leak if the result of the preceding functions were sent anywhere else, and often results in a Compute service crash causing an HTTP 500 error to be returned. As all requests to Compute are isolated from one another, the only data at risk is data present for a single request.

### Patches This bug has been fixed in version 3.16.0 of the `@fastly/js-compute` package.

### Workarounds There are no workarounds for this bug, any use of the affected functions introduces the possibility of a data leak or crash in guest code.
