## What is CVE-2026-92807?

CVE-2026-92807 is a high-severity code injection vulnerability in Save as PDF Plugin by PDFCrowd, published on 19 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The Save as PDF Plugin by PDFCrowd plugin for WordPress is vulnerable to Arbitrary Function Invocation in all versions up to, and including, 4.6.1 via the `pdf_created_callback` shortcode attribute. The `eval_shortcode()` function copies any non-`button_`/non-`email_` shortcode attribute verbatim into a custom options array without sanitization, allowlist enforcement, or capability checks, and `create_button()` AES-encrypts that array — including the attacker-supplied callback value — and embeds the resulting blob in the rendered button HTML; when the blob is later POSTed to the unauthenticated `wp_ajax_nopriv_save_as_pdf_pdfcrowd` endpoint, `save_as_pdf_pdfcrowd()` decrypts it and invokes `$options['pdf_created_callback']` as a PHP callable at line 1722 with no `is_callable()` guard, no allowlist, and no capability check. This makes it possible for authenticated attackers, with Contributor-level access and above, to invoke arbitrary PHP functions or static class methods with plugin option data as the sole argument, enabling disclosure of the site's stored PDFCrowd API key and username or further server-side abuse. Note that the encryption boundary does not mitigate this vector because the server itself encrypts the attacker-chosen callback during shortcode rendering, supplying any authenticated Contributor with a cryptographically valid blob that any unauthenticated visitor can subsequently replay to trigger invocation.

Weakness: CWE-94 (Improper Control of Generation of Code)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
