CVE-2026-39416: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ail-project ail-framework
AIL framework is an open-source platform to collect, crawl, process and analyse unstructured data. Prior to 6.8, a stored cross-site scripting (XSS) vulnerability was identified in the modal item preview functionality. When item content longer than 800 characters was processed, attacker-controlled content was returned without an explicit text/plain content type, allowing the browser to interpret the response as active HTML. This could result in execution of arbitrary JavaScript in the context of an authenticated user viewing a crafted item. This vulnerability is fixed in 6.8.
AI Analysis
Technical Summary
CVE-2026-39416 is a stored XSS vulnerability in the ail-framework open-source platform used for data collection and analysis. Specifically, in versions before 6.8, the modal item preview feature improperly neutralizes input when handling item content exceeding 800 characters. The response lacks an explicit text/plain content type, enabling browsers to render attacker-supplied content as executable HTML/JavaScript. This can lead to arbitrary script execution within the authenticated user's session. The vulnerability is addressed in version 6.8.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary JavaScript in the context of an authenticated user viewing a crafted item. This can lead to session hijacking, unauthorized actions, or data exposure within the affected application. The CVSS 4.0 base score is 8.5, indicating a high severity vulnerability with network attack vector, no user interaction required, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade ail-framework to version 6.8 or later where this vulnerability is fixed. Patch status is confirmed by the vendor stating the issue is resolved in 6.8. No other mitigation or temporary workaround is indicated in the available data.
