Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVE-2025-53892

Medium
5.3/10

Summary

Vue I18n is the internationalization plugin for Vue.js. The `escapeParameterHtml: true` option in Vue I18n is designed to protect against HTML/script injection by escaping interpolated parameters. However, in affected versions, this setting fails to prevent execution of certain tag-based payloads, such as `<img src=x onerror=...>`, if the interpolated value is inserted inside an HTML context using v-html. This may lead to a DOM-based XSS vulnerability, even when using `escapeParameterHtml: true`, if a translation string includes minor HTML and is rendered via v-html. This issue affects @intlify/core and @intlify/shared versions 9.0.0-beta.10 through 9.14.4, 10.0.0-alpha.1 through 10.0.7, 11.0.0-beta.0 through 11.1.9 and 12.0.0-alpha.1 through 12.0.0-alpha.3, petite-vue-i18n and @intlify/vue-i18n-core versions 9.2.0-alpha.7 through 9.14.4, 10.0.0-alpha.1 through 10.0.7, 11.0.0-beta.0 through 11.1.9 and 12.0.0-alpha.1 through 12.0.0-alpha.3, @intlify/core-base versions 9.0.0-beta.12 through 9.14.4, 10.0.0-alpha.1 through 10.0.7, 11.0.0-beta.0 through 11.1.9 and 12.0.0-alpha.1 through 12.0.0-alpha.3 and vue-i18n versions 9.0.0-alpha.0 through 9.14.4, 10.0.0-alpha.1 through 10.0.7, 11.0.0-beta.0 through 11.1.9 and 12.0.0-alpha.1 through 12.0.0-alpha.3.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
