Co.\u0026rsquo;s DernekWeb product. This vulnerability, discovered and reported by the Computer Emergency Response Team of the Republic of Turkey, exists in versions up to and including 30122025. An attacker can exploit this vulnerability to inject malicious scripts into the web application, which are then stored on the server and executed in the browsers of other users who access the affected content. This can lead to account compromise, data theft, or further malicious activities. Defenders should patch or mitigate this vulnerability to prevent potential exploitation.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker identifies an input field in the DernekWeb application that is vulnerable to XSS. This could be a comment field, profile information, or any other area where user-supplied data is stored and displayed.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious script, typically using JavaScript, designed to execute when the vulnerable page is loaded. This script may attempt to steal cookies, redirect the user, or deface the web page.\u003c/li\u003e\n\u003cli\u003eThe attacker submits the malicious script through the vulnerable input field. The application improperly neutralizes or fails to sanitize the input.\u003c/li\u003e\n\u003cli\u003eThe DernekWeb application stores the unsanitized input containing the malicious script in its database.\u003c/li\u003e\n\u003cli\u003eA legitimate user accesses the page or content where the malicious script is stored.\u003c/li\u003e\n\u003cli\u003eThe DernekWeb application retrieves the data from the database and renders the page, including the attacker\u0026rsquo;s malicious script.\u003c/li\u003e\n\u003cli\u003eThe user\u0026rsquo;s browser executes the malicious script, potentially performing actions without the user\u0026rsquo;s consent or knowledge.\u003c/li\u003e\n\u003cli\u003eThe attacker gains unauthorized access to the user\u0026rsquo;s account, steals sensitive information, or performs other malicious actions on behalf of the user.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this stored XSS vulnerability (CVE-2026-7498) in DernekWeb can have severe consequences. Attackers can compromise user accounts, steal sensitive data (including credentials and personal information), deface websites, and redirect users to malicious sites. Because the XSS is stored, every user who views the affected content becomes a potential victim. The number of impacted users directly correlates to the popularity and usage of the vulnerable sections within the DernekWeb application.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eApply available patches or updates for DernekWeb to address CVE-2026-7498.\u003c/li\u003e\n\u003cli\u003eImplement robust input validation and output encoding mechanisms to prevent XSS attacks.\u003c/li\u003e\n\u003cli\u003eDeploy the provided Sigma rule to detect potential exploitation attempts targeting CVE-2026-7498 based on suspicious HTTP requests.\u003c/li\u003e\n\u003cli\u003eRegularly scan web applications for vulnerabilities using automated tools and manual penetration testing.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-05-18T09:17:31Z","date_published":"2026-05-18T09:17:31Z","id":"https://feed.craftedsignal.io/briefs/2026-05-dernekweb-xss/","summary":"CVE-2026-7498 is a stored cross-site scripting (XSS) vulnerability in Basamak Information Technology Consulting and Organization Trade Ltd.
