CVE-2026-100881 Details
Description
A security vulnerability has been detected in zhistaredu StarTraining up to 3.8.1. This issue affects some unknown processing of the file application.yml. Such manipulation of the argument xss.enabled leads to cross site scripting. It is possible to launch the attack remotely. Attacks of this nature are highly complex. The exploitability is assessed as difficult. The exploit has been disclosed publicly and may be used. Not independently exploitable: a defense-in-depth absence that amplifies CVE-2026-100880. The vendor was contacted early about this disclosure but did not respond in any way.
A cross-site scripting (XSS) vulnerability has been identified in zhistaredu StarTraining versions through 3.8.1. The issue arises from a misconfiguration in the 'application.yml' file, where the 'xss.enabled' setting is turned off. This misconfiguration disables the XSS filter, allowing for the injection of malicious scripts. The vulnerability can be exploited remotely, although the complexity of the attack is considered high.
To address this vulnerability, ensure that 'xss.enabled' is set to true in production environments.
