- ----------------------------------------------------------------------- Debian LTS Advisory DLA-4263-1 [email protected] https://www.debian.org/lts/security/ Utkarsh Gupta August 04, 2025 https://wiki.debian.org/LTS

Package : ruby-graphql Version : 1.11.12-0+deb11u1 CVE ID : CVE-2025-27407 Debian Bug : 1100442

ruby-graphql is GraphQL language and runtime for Ruby. It was discovered that loading a malicious schema definition in `GraphQL::Schema.from_introspection` (or `GraphQL::Schema::Loader.load`) can result in remote code execution.
Any system which loads a schema by JSON from an untrusted source is vulnerable, including those that use GraphQL::Client to load external schemas via GraphQL introspection.

For Debian 11 bullseye, this problem has been fixed in version 1.11.12-0+deb11u1.

We recommend that you upgrade your ruby-graphql packages.

For the detailed security status of ruby-graphql please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/ruby-graphql

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the ruby-graphql packages.
