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.","categories":["Unclassified"],"product":"postiz-app","vendor":"GitroomHQ","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115933","source_modified_at":"2026-10-24T14:29:17.141Z","fetched_at":"2026-10-24T18:03:20.872036Z","product":"postiz-app","vendor":"GitroomHQ","versions":[{"version":"2.15.0","status":"affected","versionType":"semver","lessThan":"2.25.3"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115933","source_modified_at":"2026-10-24T14:29:17.141Z","fetched_at":"2026-10-24T18:03:20.872036Z","package":{"name":"postiz-app","ecosystem":null},"version":"2.25.3","basis":"first unaffected version stated in the CVE record"}],"cvss":9.9,"severity":"Critical","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-24T14:17:05.755Z","modified_at":"2026-10-24T14:29:17.141Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-115933","fetched_at":"2026-10-24T18:03:20.872036Z","source_modified_at":"2026-10-24T14:29:17.141Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/gitroomhq/postiz-app","tags":["product"]},{"source":"CVE List","url":"https://github.com/gitroomhq/postiz-app/releases/tag/v2.25.3","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/gitroomhq/postiz-app/commit/a5affe62c74e39c1e7ac960d50d8418b807d532c","tags":["patch"]},{"source":"CVE List","url":"https://gadvisory.org/advisories/PSA-2026-YT2HMH","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-24T14:29:17.141Z","content_hash":"0e1e45f496eb71aa6cbad5655842abb7006aedf514930628738bd594c4c8db18"}}
