{"id":"CVE-2026-115933","summary":"Forged signed tokens let any registered user take over other users and organizations","details":"Postiz signs its session, invitation and password reset tokens with one shared secret and without any marker of what a token is for. 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.","modified":"2026-10-25T02:46:14.513274811Z","published":"2026-10-24T14:17:05.755Z","database_specific":{"unresolved_ranges":[{"extracted_events":[{"range":[{"introduced":"2.15.0"},{"fixed":"2.25.3"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]}],"cna_assigner":"postiz","cwe_ids":["CWE-290","CWE-345","CWE-915"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/115xxx/CVE-2026-115933.json"},"references":[{"type":"ADVISORY","url":"https://gadvisory.org/advisories/PSA-2026-YT2HMH"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/115xxx/CVE-2026-115933.json"},{"type":"PACKAGE","url":"https://github.com/gitroomhq/postiz-app"},{"type":"FIX","url":"https://github.com/gitroomhq/postiz-app/commit/a5affe62c74e39c1e7ac960d50d8418b807d532c"},{"type":"ADVISORY","url":"https://github.com/gitroomhq/postiz-app/releases/tag/v2.25.3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-115933"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gitroomhq/postiz-app","events":[{"introduced":"0"},{"fixed":"a5affe62c74e39c1e7ac960d50d8418b807d532c"}],"database_specific":{"extracted_events":[{"range":[{"fixed":"a5affe62c74e39c1e7ac960d50d8418b807d532c"}],"source":"REFERENCES_TAG","original_tag":"v2.25.3"},{"source":"REFERENCES_COMMIT","range":[{"fixed":"a5affe62c74e39c1e7ac960d50d8418b807d532c"}]}]}}],"versions":["v2.25.2","v2.25.1","v2.25.0","v2.24.0","v2.23.0","v2.22.1","v2.21.10","v2.21.9","v2.21.8","v2.21.7","v2.21.6","v2.21.5","v2.21.3","v2.21.2","v2.21.1","v2.21.0","v2.20.2","v2.20.1","v2.20.0","v2.19.0","v2.18.0","v2.17.0","v2.16.0","v2.15.1","v2.15.0","v2.14.0","v2.13.0","v2.12.1","v2.12.0","v2.11.3","v2.11.1","v2.11.0","v2.10.1","v2.10.0","v2.9.0","v2.8.3","v2.8.2","v2.8.1","v2.8.0","v2.7.0","v2.6.4","v2.6.3","v2.6.2","v2.6.1","v2.5.4","v2.5.3","v2.4.3","v2.5.2","v2.5.1","v2.5.0","v2.4.2","v2.4.1","v2.4.0","v2.3.1","v2.3.0","v2.2.5","v2.2.4","v2.2.3","v2.2.1","v2.2.0","v2.1.2","v2.1.1","v2.0.8","v2.0.7","v2.0.6","v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.1","v1.65.7","v1.65.6","v1.65.5","v1.65.4","v1.65.3","v1.65.2","v1.65.1","v1.65.0","v1.64.1","v1.64.0","v1.63.0","v1.62.3","v1.62.2","v1.62.1","v1.62.0","v1.61.2","v1.61.0","v1.60.1","v1.60.0","v1.59.0","v1.58.0","v1.57.0","v1.56.0","v1.55.5","v1.54.0","v1.55.4","v1.55.3","v1.55.2","v1.55.1","v1.55.0","v1.54.1","v1.53.0","v1.52.2","v1.52.1","v1.52.0","v1.51.0","v1.50.0","v1.49.1","v1.49.0","v1.48.4","v1.48.3","v1.48.2","v1.48.1","v1.47.0","v1.45.1","v1.44.2","v1.44.1","v1.43.5","v1.43.4","v1.43.3","v1.43.2","v1.43.1","v1.43.0","v1.41.1","v1.41.0","v1.40.1","v1.40.0","v1.39.3","v1.39.2","v1.38.2","v1.38.1","v1.37.4","v1.37.3","v1.37.2","v1.37.1","v1.36.1","v1.35.1","v1.34.1","v1.33.2","v1.33.1","v1.32.1","v1.31.1","v1.30.1","v1.29.1","v1.28.1","v1.27.2","v1.26.1","v1.24.1","v1.23.2","v1.23.1","v1.22.1","v1.10.1","v1.10.0","v1.8.1","v1.7.12","v1.6.12","v1.6.9","v1.6.4","v1.6.2","v1.6.1","1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2.0","v1.1.0","v1.0.0","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-115933.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
