The Podlove Podcast Publisher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Auphonic Webhook in all versions up to, and including, 4.5.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injection is triggered by submitting a request to the Auphonic webhook endpoint with any POST body where the statusstring field is not the literal string 'Done', causing the full raw POST superglobal to be stored in the plugin log before any authentication key validation is performed.
The Podlove Podcast Publisher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'episodecontributor[..][..][comment]' Parameter in all versions up to, and including, 4.5.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The contributor comment is stored in a plugin-managed custom table, bypassing WordPress core's wpksespost filter, and the savepost hook fires without a nonce check, meaning any user who can edit posts can exploit this without further preconditions.
Unauthenticated Cross Site Scripting (XSS) in Podlove Podcast Publisher <= 4.5.4 versions.
