CVE-2026-12098
MediumCVSS 6.4Exploitation Probability (EPSS)
Low risk10th percentile — higher than 10% of all known CVEs
Summary
The PowerPress Podcasting plugin by Blubrry for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) via the 'embed' Episode Meta Field. This issue exists in all versions up to and including 11.16.8 due to insufficient input sanitization and output escaping.
Risk Assessment
The risk is that authenticated attackers with author-level access can inject arbitrary web scripts that will execute whenever a user accesses the injected page. This poses a risk of data theft or session hijacking for users.
Recommendation
It is recommended to update the PowerPress Podcasting plugin to the latest version to mitigate this vulnerability. Additionally, conducting a security audit to identify and remove potentially infected content is advisable.
Original NVD description (English source)
The PowerPress Podcasting plugin by Blubrry plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'embed' Episode Meta Field in all versions up to, and including, 11.16.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The embed value is stored via update_post_meta() rather than through WordPress core's post content pipeline, meaning kses-on-save filtering is never applied — even for Author-role users who would otherwise lack unfiltered_html — making this path unprotected by WordPress's standard role-based XSS mitigations.
