A route that refreshes the credentials of a browser-extension channel signed data taken from the request itself and stored the result where the requesting user can read it back. A user could therefore obtain a validly signed token containing any claims they choose, which the application accepts as a session, as an organization invitation with a chosen role, as a password reset or as an enterprise provisioning token.\n\nA second, narrower route that creates team invitations signs extra fields from the request body in the same way.","state":0,"publishedAt":"2026-10-24T14:17:05.755+00:00","modifiedAt":"2026-10-24T14:29:17.141+00:00","affected":[{"ecosystem":"Vendor product","name":"postiz-app","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"GitroomHQ\",\n                    \"product\": \"postiz-app\",\n                    \"packageName\": \"postiz-app\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"2.15.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"2.25.3\"\n                        }\n                    ],\n                    \"repo\": \"https://github.com/gitroomhq/postiz-app\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/gitroomhq/postiz-app","https://github.com/gitroomhq/postiz-app/releases/tag/v2.25.3","https://github.com/gitroomhq/postiz-app/commit/a5affe62c74e39c1e7ac960d50d8418b807d532c","https://gadvisory.org/advisories/PSA-2026-YT2HMH"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-115933","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-115933","identifiers":["CVE-2026-115933"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
