CVE-2026-47707: Strawberry Graphql

Medium severity, CVSS 5.3. EPSS: 0.7% chance of exploitation in the next 30 days.

Strawberry GraphQL is a library for creating GraphQL APIs. In versions 0.172.0 through0.315.6, the MaxAliasesLimiter extension in Strawberry fails to account for the multiplicative/amplification effect of FragmentSpreadNode. While it correctly counts static aliases within the AST it does not consider how many times a fragments internal aliases are expanded during execution. this allows an attacker to bypass alias limits and force the server to resolve and render a significantly higher number of aliases than allowed, potentially leading to a dos via resource exhaustion. Version 0.315.7 contains a fix for the issue.

Affected products

• Strawberry Strawberry Graphql: from 0.172.0, before 0.315.7 (fixed in 0.315.7)
