Description
Adversaries may abuse various implementations of JavaScript for execution.
Security Summary
CVE-2024-13891 is a reflected cross-site scripting (XSS) vulnerability, classified under CWE-79, affecting the Schedule WordPress plugin in versions through 1.0.0. The plugin fails to sanitize and escape a parameter before outputting it back in the page, enabling malicious script injection. It carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating high severity due to network accessibility and scope change.
An unauthenticated attacker can exploit this vulnerability remotely by tricking a targeted user, such as a high-privilege administrator, into interacting with a maliciously crafted link or input. Successful exploitation executes arbitrary JavaScript in the victim's browser context, potentially allowing session hijacking, data theft, or further site compromise, with low impacts on confidentiality, integrity, and availability.
