Versions 1.1.1 and prior contain a Stored Cross-Site Scripting (XSS) vulnerability exists in the admin role management interface. In app/Http/Controllers/Admin/RoleController.php, the datatable() method interpolates $role->name and $role->color directly into a <span> element's HTML and style attribute without sanitization, and the chained .rawColumns(['actions', 'name']) call instructs DataTables to render the name column as raw HTML, bypassing automatic output escaping. An admin with role creation or edit permissions can inject a payload such as <img src=x onerror=\"alert('XSS_POC')\"> into the name or color fields, which is persisted to the database and executes in the browser of every admin who loads the /admin/roles page. This enables session hijacking via cookie theft, credential harvesting through fake login prompts or keyloggers, lateral privilege escalation by performing admin actions on behalf of victims, and a persistent backdoor that re-executes on every page load until the malicious role record is removed. This issue has been resolved in version 1.2.0."}],"source":{"advisory":"GHSA-wpqj-xwhq-2mmh","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/Ctrlpanel-gg/panel/security/advisories/GHSA-wpqj-xwhq-2mmh","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-05-20T17:20:50.825146Z","id":"CVE-2026-34246","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":"2026-05-20T17:21:20.034Z"}}]}}
