Security Summary

CVE-2025-23883 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, affecting the Stray Random Quotes (stray-quotes) WordPress plugin developed by unalignedcoder. The issue impacts all versions of the plugin from its initial release through 1.9.9. Published on 2025-03-03, 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 (PR:N) can exploit this vulnerability remotely (AV:N) with low complexity (AC:L) by tricking a victim—such as a site visitor or administrator—into performing an action like clicking a malicious link (UI:R). Successful exploitation triggers reflected XSS, executing arbitrary scripts in the victim's browser context with changed scope (S:C), enabling low-level impacts on confidentiality (C:L), integrity (I:L), and availability (A:L), such as session hijacking, data theft, or page manipulation.
