Two of them include secrets the caller is not meant to receive.\n\nThe public API's channel delete returns the deleted integration row, including the channel's platform access token and refresh token. A third-party OAuth app permitted to delete a channel therefore receives that channel's social platform credentials and can use them against the connected account directly, outside Postiz.\n\n`GET /user/organizations` returns each organization row, including its API key, to every member of the organization. The API key is intended for admins only, so a member with a lower role can obtain it and call the public API on behalf of the organization.\n\nBoth endpoints require a valid session, API key or OAuth token and are scoped to the caller's own organization. There is no anonymous access and no cross-tenant exposure." } ], "affected": [ { "vendor": "GitroomHQ", "product": "postiz-app", "packageName": "postiz-app", "defaultStatus": "unaffected", "versions": [ { "version": "0", "status": "affected", "versionType": "semver", "lessThan": "2.25.1" } ], "repo": "https://github.com/gitroomhq/postiz-app" } ], "references": [ { "url": "https://github.com/gitroomhq/postiz-app/commit/8ad0df3df0f21299b8640568358c1b68c6464e4f", "tags": [ "patch" ], "name": "8ad0df3" }, { "url": "https://github.com/gitroomhq/postiz-app/releases/tag/v2.25.1", "tags": [ "release-notes" ], "name": "v2.25.1" }, { "url": "https://gadvisory.org/advisories/PSA-2026-4QX1WG", "tags": [ "vendor-advisory" ], "name": "GAdvisory" } ], "metrics": [ { "format": "CVSS", "cvssV4_0": { "version": "4.0", "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:L/SI:L/SA:N", "baseScore": 5.3, "baseSeverity": "MEDIUM" } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "description": "CWE-201", "cweId": "CWE-201", "type": "CWE" }, { "lang": "en", "description": "CWE-213", "cweId": "CWE-213", "type": "CWE" } ] } ], "credits": [ { "lang": "en", "value": "Gilad Resisi", "type": "reporter" }, { "lang": "en", "value": "Enno Gelhaus", "type": "coordinator" }, { "lang": "en", "value": "Gilad Resisi", "type": "remediation developer" } ], "datePublic": "2026-10-11T15:23:02.002Z", "impacts": [ { "descriptions": [ { "lang": "en", "value": "A third-party OAuth app permitted to delete a channel obtains that channel's social platform access and refresh tokens and can act on the connected account outside Postiz." } ] }, { "descriptions": [ { "lang": "en", "value": "An organization member without the admin role obtains the organization API key and can use the public API on behalf of the organization." } ] } ], "timeline": [ { "time": "2026-10-01T08:13:00.000Z", "lang": "en", "value": "Postiz has discovered the vulnerability." }, { "time": "2026-10-08T05:03:00.000Z", "lang": "en", "value": "Postiz has developed and verified a patch." }, { "time": "2026-10-11T15:16:00.000Z", "lang": "en", "value": "Postiz has created the release and published the advisory." } ] } } }
