CVE-2025-2165 is a reflected cross-site scripting vulnerability in the SH Email Alert WordPress plugin by samhoamt. The issue is due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of the 'mid' parameter. This allows unauthenticated attackers to inject arbitrary web scripts that execute when a user interacts with a maliciously crafted link. The vulnerability affects all versions up to and including 1.0. The CVSS 3.1 base score is 6.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N), indicating network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity with no impact on availability.

Successful exploitation can lead to execution of arbitrary scripts in the context of the victim's browser session, potentially allowing theft of sensitive information or session tokens. The impact is limited to confidentiality and integrity with no direct availability impact. The vulnerability requires user interaction (clicking a crafted link) and does not require authentication. There are no known exploits in the wild at this time.

No official patch or fix is currently documented. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should avoid clicking on suspicious links involving the 'mid' parameter in affected versions of the plugin. Consider disabling or removing the SH Email Alert plugin if it is not essential. Monitor vendor channels for updates or patches addressing this vulnerability.
