The task took the address to fetch from the request without checking it and asked for no form token. A prepared page on another web site could therefore make the server send the access token of the account to any address, or fetch addresses inside the server's network, in the name of a logged in administrator; a back-end user with the permission \"Manage\" could do the same directly. The token is valid for about an hour and reaches what the picker session of the account reaches.","published":"2026-10-05T17:17:10.000Z","lastModified":"2026-10-14T18:46:34.000Z","status":"Analyzed","sourceIdentifier":"security@joomla.org","cvss":{"version":"4.0","score":6.3,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:H/SI:L/SA:L/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":["svenbluege/event gallery"],"epss":{"score":0.00273,"percentile":0.19509,"date":"2026-10-26","history":[{"date":"2026-10-06","score":0.00323,"percentile":0.23192}]},"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 (0.27%).
