This flaw specifically affects the \u003ccode\u003egetInternalTaskSession\u003c/code\u003e, \u003ccode\u003egetAuthSession\u003c/code\u003e, \u003ccode\u003erequireUserAuth\u003c/code\u003e, and \u003ccode\u003erequireProjectAuthLight\u003c/code\u003e functions within the \u003ccode\u003esrc/lib/api-auth.ts\u003c/code\u003e library, which are part of the Internal Task Header Handler component. Attackers can exploit this by manipulating the \u003ccode\u003ex-internal-user-id\u003c/code\u003e HTTP request argument, leading to an authentication bypass. The vulnerability is remotely exploitable, meaning an attacker does not require local access to compromise affected systems. This vulnerability has been publicly disclosed, and an exploit for it is already available, significantly increasing the risk of widespread exploitation. The project developers were notified but have yet to release a patch or respond to the issue. The vulnerability has a CVSS v3.1 Base Score of 7.3 (High).\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker identifies a public-facing instance of waooAI waoowaoo running a vulnerable version (up to 0.4.1).\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious HTTP request targeting an application endpoint handled by the Internal Task Header Handler component.\u003c/li\u003e\n\u003cli\u003eThis request includes a manipulated \u003ccode\u003ex-internal-user-id\u003c/code\u003e HTTP header argument.\u003c/li\u003e\n\u003cli\u003eThe vulnerable functions (\u003ccode\u003egetInternalTaskSession\u003c/code\u003e, \u003ccode\u003egetAuthSession\u003c/code\u003e, \u003ccode\u003erequireUserAuth\u003c/code\u003e, \u003ccode\u003erequireProjectAuthLight\u003c/code\u003e) in \u003ccode\u003esrc/lib/api-auth.ts\u003c/code\u003e process this manipulated argument.\u003c/li\u003e\n\u003cli\u003eDue to the improper authentication vulnerability, the application fails to correctly validate the request, bypassing normal authentication mechanisms.\u003c/li\u003e\n\u003cli\u003eThe attacker gains unauthorized access to internal tasks, sessions, user, or project-related resources within the waooAI waoowaoo application.\u003c/li\u003e\n\u003cli\u003eThis unauthorized access allows the attacker to potentially view, modify, or exfiltrate sensitive data or further compromise the system.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-15557 leads to an authentication bypass, granting attackers unauthorized access to resources within the waooAI waoowaoo application. This could result in data compromise, privilege escalation, and potentially further system exploitation, depending on the scope of access gained. Since the vulnerability is remotely exploitable and a public exploit is available, organizations using affected versions face an immediate and high risk of active attacks.
