An authenticated attacker can call the convert_to_webp endpoint, which lacks a permission decorator, with a URL that redirects to internal targets such as cloud metadata services to perform SSRF, internal port scanning, or trigger a request-hang denial of service due to the missing timeout.","published":"2026-10-26T12:17:06.000Z","lastModified":"2026-10-26T20:17:51.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":5.3,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-918"],"affected":[],"epss":{"score":0.00342,"percentile":0.27553,"date":"2026-10-27","history":[{"date":"2026-10-27","score":0.00342,"percentile":0.27553}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.34%).
