This constitutes an insecure direct object reference, meaning an attacker can read other users\u2019 private collections without authorization. The lack of an ownership check means the impact is broad, exposing sensitive request data to anyone with valid credentials, potentially compromising confidentiality of multiple users' API calls. This vulnerability is an instance of CWE\u2011639 and CWE\u2011862, reflecting an authorization bypass through user\u2011controlled input and a missing authorization check, respectively.", "risk_and_exploitability": "The CVSS v3 score of 6.5 reflects moderate severity, but the EPSS score of less than 1% indicates that exploitation is unlikely at present. The vulnerability is not in the CISA KEV catalog. An attacker only needs to authenticate to the application; if they can inject a request with any collection ID, they will receive full data. No additional privileges are required beyond an authenticated session, making it relatively easy to exploit for any user with access."}}}}, "created": "2026-02-27T09:03:50.497971+00:00", "updated": "2026-04-17T14:15:21.819164+00:00", "vendors": ["hoppscotch", "hoppscotch$PRODUCT$hoppscotch"]}
