CVE-2025-0820 is a stored Cross-Site Scripting vulnerability in the Clicface Trombi WordPress plugin affecting all versions up to and including 2.08. The vulnerability is due to improper neutralization of input in the 'nom' parameter, allowing authenticated users with Contributor-level permissions or higher to inject arbitrary web scripts. These scripts execute in the context of users who view the injected pages, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 vector indicates network attack vector, low attack complexity, privileges required at low level, no user interaction, and impacts confidentiality and integrity with no availability impact.

An attacker with Contributor-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 performed in the context of other users viewing the infected pages, including theft of sensitive information or session tokens. The impact affects confidentiality and integrity but does not affect availability. No known exploits have been reported in the wild.

No official patch or remediation guidance is currently available for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict Contributor-level access to trusted users only and consider disabling or removing the Clicface Trombi plugin if feasible to reduce risk.
