CVE-2026-1923 is a stored cross-site scripting vulnerability in the Social Rocket – Social Sharing Plugin for WordPress, affecting all versions up to and including 1.3.4.2. The vulnerability is due to improper neutralization of input in the 'id' parameter, allowing authenticated attackers with at least Subscriber privileges to inject arbitrary web scripts. These scripts execute when users access the injected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS v3.1 base score of 6.4, reflecting network attack vector, low attack complexity, required privileges, no user interaction, and impact on confidentiality and integrity but not availability. No official fix or patch has been published by the vendor as of the data provided.

An attacker with Subscriber-level access or higher can exploit this vulnerability to inject persistent malicious scripts into pages generated by the plugin. This can lead to unauthorized actions such as session hijacking or data theft when other users view the infected pages. The impact affects confidentiality and integrity but does not affect availability. There are no known active exploits in the wild currently.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit user privileges to trusted users only and consider disabling or replacing the plugin if possible. Monitor for suspicious activity related to script injection. Avoid granting Subscriber-level or higher access to untrusted users.
