This can lead to various adverse effects, including the manipulation of browser caching, alteration of security-related headers, and the injection of sensitive information such as cookie values, potentially enabling session hijacking or other malicious activities.","published":"2026-05-11T10:16:13.000Z","lastModified":"2026-10-14T13:10:00.000Z","status":"Analyzed","sourceIdentifier":"ed10eef1-636d-4fbe-9993-6890dfa878f8","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-74"],"affected":["wso2/api control plane","wso2/api manager","wso2/traffic manager","wso2/universal gateway"],"epss":{"score":0.00186,"percentile":0.08071,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.19%).
