CVE-2026-55881 Details
Description
OpenReplay is a self-hosted session replay suite. From 1.22.0 before 1.27.0, getFirstMob returned 15-second presigned S3 download URLs for a session's DOM-replay recording based solely on the session path parameter, while validateProjectAccess checked only that the project belonged to the requester's tenant and did not verify that the session belonged to that project, allowing any authenticated low-privilege user to read another tenant's first 15 seconds of session-replay recording data. This issue is fixed in version 1.27.0.
A vulnerability in OpenReplay versions 1.22.0 prior to 1.27.0 allows authenticated low-privilege users to access the first 15 seconds of session-replay recordings from other tenants. This issue arises because the 'getFirstMob' function generates presigned S3 download URLs based solely on the session path parameter, without verifying that the session belongs to the project associated with the requester's tenant. The 'validateProjectAccess' check only ensures that the project is within the requester's tenant, creating a gap that can be exploited to access unauthorized replay data.
Users can upgrade to OpenReplay version 1.27.0 or later to address this vulnerability.
