CVE-2023-2751Network attack vector

Unauthenticated arbitrary media upload via CAPTCHA bypass

Published Jun 19, 2023 · Updated Dec 11, 2024

CAPTCHA bypass in Upload Resume 1.2.0 and earlier allows remote attackers to upload arbitrary media through a public resume form. The resume_upload_form shortcode accepts an upload without validating the supplied captcha parameter before processing the media file. Exploitation requires the shortcode form to be exposed, but no account or user interaction is required and uploaded media changes site content.
