CVE-2026-1649 is a stored cross-site scripting vulnerability in the Community Events WordPress plugin (jackdewey) affecting all versions up to 1.5.7. The issue is due to improper neutralization of input in the 'ce_venue_name' parameter, allowing authenticated administrators or higher to inject arbitrary web scripts. These scripts execute in the context of users viewing the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS 3.1 base score of 4.4, reflecting network attack vector, high attack complexity, high privileges required, no user interaction, and partial impact on confidentiality and integrity.

An attacker with administrator-level access can exploit this vulnerability to inject malicious scripts that execute in the browsers of users who visit the compromised pages. This can lead to partial confidentiality and integrity impacts, such as theft of sensitive information or unauthorized actions performed on behalf of users. There is no impact on availability. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict administrator access to trusted users only and consider implementing additional input validation or output encoding controls at the application or web server level to mitigate the risk of script injection.
