CVE-2026-2355 describes a Stored Cross-Site Scripting vulnerability in the My Calendar – Accessible Event Manager plugin for WordPress, affecting all versions up to and including 3.7.3. This flaw allows authenticated attackers with Contributor-level access or higher to inject malicious web scripts via the [my_calendar_upcoming] shortcode's 'template' attribute. The vulnerability arises because the plugin's use of stripcslashes() bypasses WordPress's sanitization, decoding C-style hex escape sequences at render time. The vulnerability has a CVSS score of 6.4 (Medium), indicating a network-based attack with low complexity and requiring low privileges, leading to low impact on confidentiality and integrity. There is no evidence of active exploitation, no known public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage. The EPSS score is very low, suggesting a low probability of exploitation.
