CVE-2026-55881
OpenReplay is a self-hosted session replay suite.
Overview
CVE-2026-55881 is a known-severity vulnerability. It was published on July 10, 2026.
Technical 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.
