Published: 23 September 2025
Summary
CVE-2025-10147 is a critical-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Wordpress (inferred from references). Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 26.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-10147 is a high-severity vulnerability in the Podlove Podcast Publisher plugin for WordPress, affecting all versions up to and including 4.2.6. The issue stems from missing file type validation in the 'move_as_original_file' function within the plugin's image handling code, enabling arbitrary file uploads to the affected site's server. Classified under CWE-434 (Unrestricted Upload of File with Dangerous Type), it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), highlighting its critical risk profile.
Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity and no user interaction required. By uploading arbitrary files, such as web shells or executable scripts, attackers gain the potential for remote code execution on the server, leading to full compromise of confidentiality, integrity, and availability.
Advisories point to the vulnerable code at line 465 in lib/model/image.php of version 4.2.6, with a fix available in changeset 3364994 on the WordPress plugin Trac repository. Security practitioners should reference the Wordfence threat intelligence page for detailed analysis and apply the patch by updating to a version beyond 4.2.6.
