It took the address of the article from the shared link and printed it into the page without checking or escaping it; with the link type \"Image Page with Redirect\" it followed the address at once. A prepared link could therefore run a script in the page, in the session of the visitor who opened it, or send the visitor to another web site. Nothing on the server is changed or read by the server.","published":"2026-10-05T16:17:05.000Z","lastModified":"2026-10-14T18:48:31.000Z","status":"Analyzed","sourceIdentifier":"security@joomla.org","cvss":{"version":"4.0","score":5.3,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/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-352","CWE-601"],"affected":["svenbluege/event gallery"],"epss":{"score":0.00091,"percentile":0.00473,"date":"2026-10-27","history":[{"date":"2026-10-06","score":0.00151,"percentile":0.03664}]},"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 (0.09%).
