CVE-2026-45296 Details
Description
OpenReplay is a self-hosted session replay suite. Prior to 1.26.0, OpenReplay's Python API exposes several app_apikey routes that trust a caller-provided projectKey after validating only that the API key itself is valid and that the target projectKey exists. The authorization flow does not verify that the authenticated API key and the requested project belong to the same tenant. Because the public tracker design exposes projectKey to browser-side code, an attacker who owns any valid API key for their own tenant can target another tenant's project by reusing that public projectKey. The vulnerable routes allow the attacker to enumerate victim user sessions and then retrieve sensitive session event data across the tenant boundary. This vulnerability is fixed in 1.26.0.
A cross-tenant information disclosure vulnerability has been identified in OpenReplay's Python API, prior to version 1.26.0. The issue arises in several 'app_apikey' routes that accept a caller-provided 'projectKey'. The API only validates the authenticity of the API key and the existence of the projectKey, without ensuring that both belong to the same tenant. This flaw allows an attacker with a valid API key to access another tenant's project by reusing its public projectKey. Exploitation of this vulnerability enables the attacker to enumerate user sessions and retrieve sensitive session event data from the targeted tenant.
Users are advised to update OpenReplay to version 1.26.0 or later, where this vulnerability has been fixed.
