GHSA-3h96-34p3-xm76 — graphql
MEDIUMGHSA-3h96-34p3-xm76 is a medium-severity (CVSS 5.3) vulnerability in graphql. A fix is available for graphql — see the affected versions and patch details below.
GraphQL-Ruby's Ruby lexer does not count comment tokens for the purposes of max_query_string_tokens
Real-World Exposure
graphql💎graphql💎graphql💎graphqlReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects RubyGems packages — download data is not available via public APIs for these ecosystems.
Description
GraphQL-Ruby's max_query_string_tokens configuration didn't count comment tokens against the limit, allowing strings to be processed even after the configured maximum had actually been reached.
In patched versions, the Ruby lexer does count these tokens.
GraphQL-CParser is not affected by this problem.
max_query_string_tokens was introduced in v2.3.1. Each 2.x version has received a new patch release for including a fix.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for graphql, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update graphql to 2.6.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3h96-34p3-xm76 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-3h96-34p3-xm76 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-3h96-34p3-xm76. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-3h96-34p3-xm76 in your dependencies?
O3 Security finds GHSA-3h96-34p3-xm76 across RubyGems dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
