AI Analysis
Technical Summary
The Simple Banner WordPress plugin (versions up to 3.0.5) contains a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Authenticated administrators can inject malicious scripts via the plugin's admin settings, which execute when users access affected pages. This vulnerability affects multi-site installations or those with unfiltered_html disabled. The CVSS 3.1 base score is 4.4, reflecting network attack vector, high attack complexity, required privileges at the administrator level, no user interaction, and impacts on confidentiality and integrity but not availability. No patch or remediation details are currently available.
Potential Impact
An authenticated attacker with administrator privileges can inject and store malicious scripts within the plugin's settings. These scripts execute in the context of users visiting the affected pages, potentially leading to unauthorized actions or data exposure limited to confidentiality and integrity impacts. The vulnerability does not affect availability and requires high privileges and a multi-site or restricted unfiltered_html environment to be exploitable.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict administrator access to trusted users only and consider disabling or removing the plugin in multi-site or restricted unfiltered_html environments. Monitor vendor communications for updates on patches or official mitigations.
