CVE-2026-1252 is a stored cross-site scripting vulnerability in the Events Listing Widget WordPress plugin, affecting all versions up to 1.3.4. The issue is due to improper neutralization of input in the 'Event URL' parameter, allowing authenticated users with Author-level privileges or higher to inject arbitrary web scripts. These scripts execute in the context of users visiting the injected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 base score of 6.4, reflecting network attack vector, low attack complexity, privileges required at the Author level, no user interaction, and impacts on confidentiality and integrity with no availability impact. No patch or official fix details are currently available.

An attacker with Author-level access or higher can exploit this vulnerability to inject and store malicious scripts via the 'Event URL' parameter. These scripts execute in the browsers of users who view the affected pages, potentially compromising user sessions or data confidentiality and integrity. The vulnerability does not impact availability. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Author-level access to trusted users only and consider disabling or removing the Events Listing Widget plugin if possible.
