CVE-2025-8293: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in Theerawat Patthawee Intl DateTime Calendar
The Intl DateTime Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘date’ parameter in all versions up to, and including, 1.0.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2025-8293 is a stored cross-site scripting vulnerability in the Intl DateTime Calendar WordPress plugin by Theerawat Patthawee. The vulnerability exists due to improper neutralization of input in the 'date' parameter, allowing authenticated users with Contributor or higher privileges to inject arbitrary web scripts. These scripts execute when other users access the injected page, potentially compromising confidentiality and integrity. The vulnerability affects all versions up to and including 1.0.1. The CVSS 3.1 base score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, and partial impact on confidentiality and integrity without availability impact. No patch or vendor advisory is currently available.
Potential Impact
An attacker with Contributor-level or higher privileges can inject persistent malicious scripts via the 'date' parameter. This can lead to unauthorized script execution in the context of other users viewing the affected pages, potentially exposing sensitive information or enabling further attacks. The impact is limited to confidentiality and integrity with no direct availability impact. The vulnerability requires authenticated access, reducing the attack surface compared to unauthenticated XSS.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Contributor-level access to trusted users only and consider disabling or removing the Intl DateTime Calendar plugin if feasible. Monitor for updates from the vendor or security advisories for a patch or official mitigation.
