DescriptionNVD

The Custom Logo plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 2.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

AnalysisAI

Stored XSS in the WordPress Custom Logo plugin through version 2.2 allows authenticated administrators to inject malicious scripts into admin settings that execute for other users. This affects multi-site WordPress installations and single-site setups where unfiltered_html is disabled, requiring high-privilege attacker access but enabling persistent script injection across affected pages.

RemediationAI

Within 30 days: Identify affected systems running for WordPress is vulnerable to Stored Cross-Site Scripting v and apply vendor patches as part of regular patch cycle. Verify Content-Security-Policy and output encoding.
