Prior to version 2026.2.0, the `userCollection` GraphQL query accepts an arbitrary collection ID and returns the full collection data — including title, type, and the serialized `data` field containing HTTP requests with headers and potentially secrets — to any authenticated user, without verifying that the requesting user owns the collection. This is an Insecure Direct Object Reference (IDOR) caused by a missing authorization check that exists on every other operation in the same resolver. Version 2026.2.0 fixes the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-639","CWE-862"],"references":["https://github.com/hoppscotch/hoppscotch/releases/tag/2026.2.0","https://github.com/hoppscotch/hoppscotch/security/advisories/GHSA-m5pg-r4jp-qq75"],"products":["hoppscotch:hoppscotch"],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-28217","score":0.00415,"percentile":0.3583,"date":"2026-10-31"},"kev":null,"osv":[],"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).
