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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-400"],"references":["https://github.com/strawberry-graphql/strawberry/releases/tag/0.315.7","https://github.com/strawberry-graphql/strawberry/security/advisories/GHSA-fr49-mhgj-crfc","https://github.com/strawberry-graphql/strawberry/security/advisories/GHSA-fr49-mhgj-crfc"],"products":["strawberry:strawberry_graphql"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-47707","score":0.00466,"percentile":0.40344,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-fr49-mhgj-crfc","url":"https://osv.dev/vulnerability/GHSA-fr49-mhgj-crfc","summary":"Strawberry GraphQL's Bypass of MaxAliasesLimiter via Fragment Spreads leading to GraphQL Alias Amplification","modified":"2026-07-13T07:26:42.996959310Z","packages":[{"ecosystem":"PyPI","name":"strawberry-graphql","purl":"pkg:pypi/strawberry-graphql","ranges":[">=0.172.0 <0.315.7"],"fixed":["0.315.7"]}]},{"id":"PYSEC-2026-2284","url":"https://osv.dev/vulnerability/PYSEC-2026-2284","summary":"","modified":"2026-07-13T07:15:42.523386421Z","packages":[{"ecosystem":"PyPI","name":"strawberry-graphql","purl":"pkg:pypi/strawberry-graphql","ranges":[">=0.172.0 <0.315.7"],"fixed":["0.315.7"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
