CVE-2025-26994 is a Stored Cross-site Scripting (XSS) vulnerability found in the softdiscover Zigaform – Price Calculator & Cost Estimation Form Builder Lite plugin, versions up to 7.4.2. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing malicious scripts to be stored and later executed in the context of users visiting the affected pages. This type of vulnerability enables attackers to perform actions such as session hijacking, cookie theft, defacement, or redirecting users to malicious websites. The flaw does not require authentication or user interaction beyond visiting a compromised page, increasing the risk of exploitation. Although no public exploits have been reported yet, the widespread use of this plugin in WordPress environments for price calculation and cost estimation forms makes it a valuable target for attackers. The lack of a CVSS score means severity must be inferred from the nature of the vulnerability, which affects confidentiality and integrity with a broad scope due to the plugin's usage in many websites. The vulnerability highlights the importance of proper input validation, output encoding, and security controls in web application components that handle user input. The absence of patch links suggests that fixes may not yet be available, emphasizing the need for proactive mitigation strategies.

The impact of CVE-2025-26994 can be significant for organizations using the affected plugin. Successful exploitation allows attackers to inject persistent malicious scripts into web pages, which execute in the browsers of visitors. This can lead to theft of sensitive information such as session cookies, enabling account takeover or impersonation. It can also facilitate phishing attacks by redirecting users to fraudulent sites or defacing the website, damaging brand reputation and customer trust. For e-commerce and service-oriented websites relying on Zigaform for price calculations, this could disrupt business operations and lead to financial losses. Additionally, the vulnerability could be leveraged as a foothold for further attacks within the network if administrative users are targeted. The broad deployment of WordPress and the plugin's niche in cost estimation forms means a wide range of industries could be affected, from retail to professional services. Without timely mitigation, the risk of exploitation increases as attackers develop and share exploit code.

1. Monitor for official patches or updates from softdiscover and apply them immediately once available to remediate the vulnerability. 2. Until patches are released, implement Web Application Firewall (WAF) rules to detect and block malicious payloads targeting the plugin's input fields. 3. Employ strict input validation and output encoding on all user-supplied data processed by the plugin to prevent script injection. 4. Configure Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of any injected code. 5. Regularly audit and sanitize stored data within the plugin's database entries to identify and remove any malicious scripts. 6. Educate website administrators and developers about secure coding practices and the risks of XSS vulnerabilities. 7. Limit plugin usage to trusted environments and consider alternative plugins with better security track records if immediate patching is not feasible. 8. Monitor website traffic and logs for unusual activity that may indicate exploitation attempts.
