Summary
The Formidable Charts plugin for WordPress up to version 2.0.1 has a Directory Traversal vulnerability via the 'frm_graph' parameter. An unauthenticated attacker can read the contents of arbitrary files on the server if certain conditions are met.
Risk Assessment
An attacker can access sensitive information such as configuration files, user data, or other confidential data stored on the server.
Recommendation
Update the Formidable Charts plugin to a patched version. Additionally, ensure the uploads directory is properly secured.

- CVE-2026-118636Critical
The JavaNativeMessageDecoder class in the Apache MINA 3.0 codec module calls ObjectInputStream.readObject() on frame bytes without any class filter. An application that places it in front of an untrusted peer is exposed to gadget-chain remote code execution. The 3.0.0 branch is inactive and no fix will be released for it.
- CVE-2026-120209Critical
AJ-Report through 1.7.1 signs share tokens with a hard-coded JWT secret, allowing attackers to forge valid Share-Tokens offline. Attackers can mint a token with reportCode 'dataSet' to access the testTransform endpoint, which passes scripts to GroovyClassLoader for unauthenticated remote code execution.
- CVE-2026-120201Critical
Jpom 2.10.0 through 2.11.12 contains an authentication bypass vulnerability that allows unauthenticated attackers to gain super-administrator access by injecting query conditions into the JPOM-USER-TOKEN header. Attackers can send a value like 'is not null', which Hutool's Condition parser treats as an operator, then execute commands through Jpom's script features.
- CVE-2026-118235Critical
The SimpleForm plugin for WordPress (versions up to and including 3.10.2) is vulnerable to arbitrary file upload via the handle_upload function. Missing a server-side file key allowlist and pre-sanitization extension derivation allows a trailing-dot filename to bypass all extension and MIME validation, enabling unauthenticated attackers to upload executable files and achieve remote code execution. The only access control is a nonce printed into every public form's data-nonce attribute, trivially obtainable by any unauthenticated visitor.
- CVE-2026-103882Critical
The Acadlix LMS plugin for WordPress (versions up to and including 1.1.9) is vulnerable to arbitrary file deletion due to insufficient file path validation in the post_delete_assessment_file_by_id function. Authenticated attackers with subscriber-level access or higher can delete arbitrary files on the server, potentially leading to remote code execution when critical files such as wp-config.php are deleted. The route's permission callback only verifies a generic wp_rest nonce emitted in the public acadlixOptions JavaScript object on every frontend page, effectively reducing the authentication requirement to unauthenticated.
Original NVD description (English source)
The Formidable Charts plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.0.1 via the 'frm_graph' parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Successful exploitation requires Formidable Forms Lite, Formidable Forms Pro, and Formidable Charts to be active and requires the wp-content/uploads/frm-charts/ directory to exist, normally after an image-format chart is rendered.
