Sep 18, 2026Save as PDF Plugin by PDFCrowd: Arbitrary Function InvocationCVE-2026-92807 · WordPress plugins & themes · reported by WordfenceHigh 8.8
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 bec

Aug 28, 2026Tutor LMS – eLearning and online course solution: Remote Code Execution limited to zero-argument function invocationCVE-2026-16759 · WordPress plugins & themes · reported by WordfenceMedium 6.5
The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Remote Code Execution limited to zero-argument function invocation in all versions up to, and including, 4.0.5 via the tutor_course_filter_ajax AJAX action. This is due to missing authorization on the handler combined with unsanitized array keys being passed to extract() inside tutor_load_template(), allowing attacker-controlled POST data to overwrite the local $template variable and, in the resulting templates/single-content-loader.php template, the $method_map and $context variables invoked at $method_map[$context](). This makes it possible for unauthenticated attackers to call an arbitrary zero-argument PHP function server-side and, via WordPress core edit_user(), to create a persistent subscriber-level account from request parameters.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
