CVE-2024-1110 is a vulnerability identified in the Podlove Podcast Publisher plugin for WordPress, maintained by eteubert. The issue arises from a missing capability check in the plugin's init() function across all versions up to and including 4.0.11. This missing authorization allows unauthenticated attackers to import and modify the plugin's settings remotely without any authentication or user interaction. The vulnerability is classified under CWE-862 (Missing Authorization), indicating that the plugin fails to verify whether the requester has the necessary permissions before allowing sensitive operations. The absence of this check means that attackers can manipulate podcast publishing configurations, potentially altering how content is managed or displayed. The CVSS v3.1 base score is 5.3, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no confidentiality impact (C:N), limited integrity impact (I:L), and no availability impact (A:N). No patches or exploit code are currently publicly available, and no known active exploitation has been reported. However, the vulnerability's presence in a widely used WordPress plugin makes it a notable risk for podcast publishers and WordPress site administrators.

The primary impact of CVE-2024-1110 is unauthorized modification of the Podlove Podcast Publisher plugin settings, which compromises the integrity of podcast publishing configurations. Attackers could potentially alter podcast metadata, feed settings, or other critical parameters, leading to misinformation, content manipulation, or disruption of podcast distribution workflows. While confidentiality and availability are not directly affected, the integrity breach could undermine trust in the podcast content and the hosting platform. For organizations relying on Podlove Podcast Publisher, especially media companies, educational institutions, and content creators, this could result in reputational damage and operational disruptions. Since exploitation requires no authentication or user interaction, the attack surface is broad, increasing the likelihood of opportunistic attacks. The lack of known exploits in the wild reduces immediate risk but does not eliminate the potential for future attacks once exploit code becomes available.

To mitigate CVE-2024-1110, organizations should immediately update the Podlove Podcast Publisher plugin to a version that includes the missing authorization check once released by the vendor. Until a patch is available, administrators should restrict access to WordPress administrative endpoints using web application firewalls (WAFs) or IP whitelisting to limit exposure to unauthenticated requests. Implementing strict access controls on the WordPress backend and monitoring logs for unusual import or configuration changes can help detect exploitation attempts. Additionally, disabling or removing the plugin temporarily may be considered if the risk is unacceptable and no patch is available. Site owners should also ensure that WordPress and all plugins are regularly updated and follow the principle of least privilege for user roles. Employing security plugins that monitor for unauthorized changes and integrating intrusion detection systems can provide further protection.
