Security Summary

CVE-2025-23846 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Reflected Cross-site Scripting (XSS) under CWE-79, affecting the thaikolja Flexible Blogtitle WordPress plugin. This issue impacts all versions from n/a through 0.1 inclusive. Published on 2025-01-22T15:15:24.570, 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).

Unauthenticated attackers accessible over the network can exploit this vulnerability with low attack complexity, though it requires user interaction, such as visiting a maliciously crafted URL. Successful exploitation enables reflected XSS, where attacker-controlled input is reflected unsafely in the web page, allowing script injection. The changed scope (S:C) permits impacts extending beyond the vulnerable component, resulting in low confidentiality, integrity, and availability effects for affected users.
