CVE-2025-23658 identifies a reflected cross-site scripting (XSS) vulnerability in the Advanced Angular Contact Form component developed by Tauhidul Alam, affecting all versions up to and including 1.1.0. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows malicious scripts to be injected and executed in the context of the victim's browser session. This type of vulnerability is classified as Reflected XSS, where the malicious payload is embedded in a URL or form input and reflected back in the server's response without proper sanitization or encoding. The Advanced Angular Contact Form is a reusable Angular component designed to facilitate contact form functionality in web applications. Since Angular applications are widely used for modern web development, this vulnerability can impact any website or service integrating this component. Exploitation requires no authentication but depends on social engineering to convince users to interact with crafted URLs or inputs. The vulnerability can lead to theft of session cookies, redirection to malicious sites, or execution of arbitrary JavaScript, compromising user confidentiality and integrity. No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The CVSS score is not provided, but the vulnerability is significant due to the potential for client-side attacks and data compromise.

The primary impact of CVE-2025-23658 is on the confidentiality and integrity of user data interacting with web applications using the vulnerable Advanced Angular Contact Form. Attackers can exploit the reflected XSS flaw to execute arbitrary JavaScript in victims' browsers, potentially stealing session tokens, cookies, or other sensitive information. This can lead to account takeover, unauthorized actions on behalf of users, phishing attacks, and distribution of malware. The vulnerability does not directly affect server availability but can damage the reputation and trustworthiness of affected organizations. Since the component is used in web applications worldwide, any organization relying on this contact form may expose their users to these risks. The ease of exploitation without authentication and the widespread use of Angular frameworks increase the threat's reach. Organizations handling sensitive user data, such as financial, healthcare, or e-commerce platforms, face higher risks due to the potential for data breaches and fraud. Additionally, attackers may leverage this vulnerability as an initial vector for more complex attacks or lateral movement within compromised environments.

To mitigate CVE-2025-23658, organizations should first monitor for official patches or updates from the vendor Tauhidul Alam and apply them promptly once available. In the absence of patches, developers should implement strict input validation and output encoding on all user-supplied data processed by the Advanced Angular Contact Form component. Utilizing Angular's built-in sanitization mechanisms and security best practices, such as the DomSanitizer service, can help prevent injection of malicious scripts. Web application firewalls (WAFs) can be configured to detect and block common XSS attack patterns targeting the contact form endpoints. Additionally, organizations should educate users about the risks of clicking suspicious links and implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Regular security testing, including automated scanning and manual penetration testing focused on XSS vulnerabilities, is recommended to identify and remediate similar issues. Finally, developers should consider replacing or refactoring the vulnerable component with more secure alternatives if timely patches are not forthcoming.
