Affected versions are subject to a Denial-of-Service (DoS) type vulnerability which causes the Router to panic and terminate when GraphQL Subscriptions are enabled.  It can be triggered when **all of the following conditions are met**: 1. Running Apollo Router v1.28.0, v1.28.1 or v1.29.0 (\"impacted versions\"); **and** 2. The Supergraph schema provided to the Router (either via Apollo Uplink or explicitly via other configuration) **has a `subscription` type** with root-fields defined; **and** 3. The YAML configuration provided to the Router **has subscriptions enabled** (they are _disabled_ by default), either by setting `enabled: true` _or_ by setting a valid `mode` within the `subscriptions` object (as seen in [subscriptions' documentation](https://www.apollographql.com/docs/router/executing-operations/subscription-support/#router-setup)); **and** 4. An [anonymous](https://spec.graphql.org/draft/#sec-Anonymous-Operation-Definitions) (i.e., un-named) `subscription` operation (e.g., `subscription { ... }`) is received by the Router If **all four** of these criteria are met, the impacted versions will panic and terminate.  There is no data-privacy risk or sensitive-information exposure aspect to this vulnerability. This is fixed in Apollo Router v1.29.1. Users are advised to upgrade. Updating to v1.29.1 should be a clear and simple upgrade path for those running impacted versions.  However, if Subscriptions are **not** necessary for your Graph – but are enabled via configuration — then disabling subscriptions is another option to mitigate the risk.","published_at":"2023-09-05T18:31:43.185000Z","last_modified_at":null,"cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":true,"ssvc_technical_impact":"partial","cwes":["CWE-755"],"nvd_references":["https://github.com/apollographql/router/security/advisories/GHSA-w8vq-3hf9-xppx","https://github.com/apollographql/router/commit/b295c103dd86c57c848397d32e8094edfa8502aa","https://github.com/apollographql/router/releases/tag/v1.29.1"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:36:18.150707Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"apollographql","vendor_name":"apollographql","product_slug":"router","product_name":"router","version_start":">= 1.28.0, < 1.29.1","version_start_inclusive":true,"version_end":">= 1.28.0, < 1.29.1","version_end_inclusive":true,"cpe23_uri":"cve5:apollographql:router:>= 1.28.0, < 1.29.1:>= 1.28.0, < 1.29.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/apollographql/router/security/advisories/GHSA-w8vq-3hf9-xppx","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/apollographql/router/commit/b295c103dd86c57c848397d32e8094edfa8502aa","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/apollographql/router/releases/tag/v1.29.1","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2023-09-05T18:31:43.185000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:29:46.401874Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:29:46.401874Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:29:46.401874Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:36:18.150707Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:36:18.150707Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:36:18.150707Z","label":"SSVC decision revised","source":"vulnrichment"}]}
