This flaw arises from the improper validation of symbolic links during archive extraction. An attacker could exploit this vulnerability to execute arbitrary code on the system, potentially leading to complete system compromise. This vulnerability was disclosed on May 27, 2026, and has a CVSS v3.1 base score of 9.8, indicating a critical severity. Successful exploitation requires no user interaction and can be performed remotely.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker crafts a malicious archive containing symbolic links.\u003c/li\u003e\n\u003cli\u003eThe attacker uploads the malicious archive to the Langflow server.\u003c/li\u003e\n\u003cli\u003eLangflow extracts the archive without properly validating the symbolic links.\u003c/li\u003e\n\u003cli\u003eThe symbolic links point to locations outside the intended extraction directory.\u003c/li\u003e\n\u003cli\u003eFiles are created or overwritten in unintended locations due to path traversal.\u003c/li\u003e\n\u003cli\u003eThe attacker overwrites a critical system file with malicious code.\u003c/li\u003e\n\u003cli\u003eThe compromised system file is executed.\u003c/li\u003e\n\u003cli\u003eThe attacker achieves remote code execution on the Langflow server.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-7524 can lead to complete compromise of the Langflow server.
