A weakness has been identified in BrowserOperator browser-operator-core up to 0.6.0. Affected is the function startsWith of the file scripts/component_server/server.js. Executing a manipulation of the argument request.url can lead to path traversal. The attack can be launched remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Path traversal in browser-operator-core versions up to 0.6.0 allows remote unauthenticated attackers to read, write, and potentially delete arbitrary files on the server by manipulating the request.url parameter in the startsWith function of server.js. Publicly available exploit code exists (GitHub issue #96), enabling trivial exploitation with no user interaction. …

RemediationAI
Within 24 hours: Inventory all systems running browser-operator-core up to version 0.6.0 and isolate affected instances from production networks if possible. Within 7 days: Evaluate vendor alternatives or implement network-level access controls (WAF rules blocking malicious request.url patterns, IP whitelisting) to limit exposure while awaiting patch availability; verify no indicators of compromise in server logs. …
