The vulnerability, designated as CVE-2026-7234, resides in the \u003ccode\u003estartsWith\u003c/code\u003e function within the \u003ccode\u003escripts/component_server/server.js\u003c/code\u003e file. By manipulating the \u003ccode\u003erequest.url\u003c/code\u003e argument, an attacker can bypass path restrictions and potentially access sensitive files on the server. The vulnerability can be exploited remotely, and a proof-of-concept exploit is publicly available. The BrowserOperator project has been notified, but a patch has not yet been released. Successful exploitation could lead to information disclosure and unauthorized access to system resources.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies a vulnerable BrowserOperator browser-operator-core instance running a version prior to 0.6.0.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious HTTP request targeting the \u003ccode\u003ecomponent_server/server.js\u003c/code\u003e endpoint.\u003c/li\u003e\n\u003cli\u003eThe crafted request includes a manipulated \u003ccode\u003erequest.url\u003c/code\u003e argument designed to bypass the \u003ccode\u003estartsWith\u003c/code\u003e function\u0026rsquo;s intended path restrictions.\u003c/li\u003e\n\u003cli\u003eThe \u003ccode\u003estartsWith\u003c/code\u003e function fails to properly sanitize or validate the \u003ccode\u003erequest.url\u003c/code\u003e input.\u003c/li\u003e\n\u003cli\u003eThe application uses the attacker-controlled \u003ccode\u003erequest.url\u003c/code\u003e to construct a file path.\u003c/li\u003e\n\u003cli\u003eThe application attempts to read a file based on the constructed path, traversing directories outside of the intended scope.\u003c/li\u003e\n\u003cli\u003eIf successful, the contents of the targeted file are returned to the attacker in the HTTP response.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this vulnerability allows a remote attacker to read arbitrary files on the server hosting the BrowserOperator browser-operator-core application.
