CVE-2026-92807Network attack vector

Authenticated PHP function invocation via callback injection

Published Sep 19, 2026 · Updated Sep 19, 2026

Code injection in Save as PDF Plugin by PDFCrowd 4.6.1 and earlier allows remote authenticated users to invoke PHP callables. The eval_shortcode() path accepts an attacker-chosen pdf_created_callback, and save_as_pdf_pdfcrowd() decrypts and invokes it without authorization or an allowlist. Contributor-level access is required to mint a valid encrypted blob, which can then disclose stored PDFCrowd credentials or enable further server-side abuse.
