CVE-2026-54501 Details
Description
Browsertrix is a high-fidelity, browser-based crawling service for web archiving that can be self-hosted or used through Webrecorder's hosted instance. From 1.15.0 until 1.22.8, Browsertrix improperly sanitizes Git URLs specified as Custom Behaviors, allowing command injection through /api/orgs/*/crawlconfigs/validate/custom-behavior. A user with crawler or administrator permission on the specific instance can supply a crafted Git URL that executes arbitrary operating-system commands in the backend pod. Open registration or hosted free-trial access can make the required role broadly obtainable. Successful exploitation can expose, modify, or delete application database records, archived items, browser profiles, storage data, proxy credentials, and other configured service data. This issue is fixed in version 1.22.8.
A command injection vulnerability has been identified in Browsertrix versions 1.15.0 prior to 1.22.8. The issue arises from improper sanitization of Git URLs used in Custom Behaviors, allowing users with crawler or administrator permissions to execute arbitrary operating system commands on the backend pod. This exploitation can lead to unauthorized access, modification, or deletion of application database records, archived items, browser profiles, storage data, proxy credentials, and other configured service data.
Users can upgrade to Browsertrix version 1.22.8 or later, where this vulnerability has been patched. For those using Browsertrix 1.22.8, it is recommended to rotate secrets such as database credentials, storage bucket keys, and SSH keys for proxy servers. Instructions for updating a Browsertrix deployment are available in the Browsertrix documentation.
