Prior to versions 2.6.25 and 3.0.8, src/Sulu/Bundle/MediaBundle/Controller/MediaStreamController.php allows the /media/{id}/download/{slug} route and its administration variant to honor the inline query parameter for scriptable MIME types. The vulnerable stored Content-Type values include text/html, application/xhtml+xml, text/xml, and application/xml. An attacker with media upload permission can store an HTML, XHTML, or XML document and create a link using inline=1, causing the application to return the file on the Sulu origin instead of forcing Content-Disposition attachment. When an authenticated victim opens the link, attacker-controlled JavaScript can execute with the victim's Sulu-origin session and can read data or perform actions as that victim. This issue is fixed in versions 2.6.25 and 3.0.8."}],"source":{"advisory":"GHSA-pp4x-ccxq-6r33","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-01T14:28:25.862691Z","id":"CVE-2026-82396","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-01T14:29:00.823Z"}}]}}
