{"id":"CVE-2026-45297","summary":"Cross-tenant IDOR on feature-flag and assist-stats routes via {project_id} case mismatch","details":"OpenReplay is a self-hosted session replay suite. Prior to 1.26.0, there is a cross-tenant IDOR on feature-flag and assist-stats routes via {project_id} case mismatch. ProjectAuthorizer.__call__ (OSS api/auth/auth_project.py:14-38 and EE ee/api/auth/auth_project.py:14-46) only runs projects.is_authorized(project_id, tenant_id, user_id) + projects.get_project(tenant_id, project_id) when self.project_identifier == \"projectId\" (camelCase). For EE multi-tenant, feature-flag queries only filter on project_id, never tenant_id. Any authenticated user in tenant A can read/update/delete feature-flag rows belonging to tenant B by iterating the sequential integer project_id + feature_flag_id. OSS is single-tenant by design ({\"errors\":[\"tenants already registered\"]} on second signup) so there's no cross-tenant impact This vulnerability is fixed in 1.26.0.","aliases":["GHSA-5m23-rcj4-cgjx"],"modified":"2026-07-08T08:12:43.252419Z","published":"2026-05-28T16:50:38.672Z","database_specific":{"cwe_ids":["CWE-285","CWE-639","CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45297.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45297.json"},{"type":"ADVISORY","url":"https://github.com/openreplay/openreplay/security/advisories/GHSA-5m23-rcj4-cgjx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45297"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openreplay/openreplay","events":[{"introduced":"0"},{"fixed":"f450d5dbc689f15ea803ee864b5c598f3f013c6d"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.26.0"}],"source":"AFFECTED_FIELD"}}],"versions":["pre-v1.26.0","pre-v1.25.0","pre-v1.24.0","0.6.17","or-argo-test","pre-v1.22.0","pre-v1.21.0","pre-v1.20.0","v0.5.0","pre-v1.19.0","argo","pre_v1.18.0","v.1.14.0","v1.9.0","v1.5.2","v1.5.1","v1.5.0","v1.4.0","v1.3.6","v1.3.0","v1.2.0","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45297.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
