HighCVE-2026-65443

BackWPup <= 5.7.4 - Unauthenticated Stored Cross-Site Scripting

Affected versions: *-5.7.4

Vulnerability type: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Affected software, patched versions and attribution

The BackWPup plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 5.7.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

BackWPup <= 5.6.6 - Authenticated (Administrator+) Local File Inclusion via 'block_name' Parameter

Affected versions: *-5.6.6

Vulnerability type: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Affected software, patched versions and attribution

The BackWPup plugin for WordPress is vulnerable to Local File Inclusion via the `block_name` parameter of the `/wp-json/backwpup/v1/getblock` REST endpoint in all versions up to, and including, 5.6.6 due to a non-recursive `str_replace()` sanitization of path traversal sequences. This makes it possible for authenticated attackers, with Administrator-level access and above, to include arbitrary PHP files on the server via crafted traversal sequences (e.g., `....//`), which can be leveraged to read sensitive files such as `wp-config.php` or achieve remote code execution in certain configurations. Administrators have the ability to grant individual users permission to handle backups, which may then allow lower-level users to exploit this vulnerability.

BackWPup 5.0.0 - 5.6.2 - Authenticated (BackWPup Helper+) Privilege Escalation via Arbitrary Options Update

Affected versions: 5.0.0-5.6.2

Vulnerability type: CWE-862 Missing Authorization

Affected software, patched versions and attribution

The BackWPup – WordPress Backup & Restore Plugin plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the save_site_option() function in all versions 5.0.0 to 5.6.2. This makes it possible for authenticated attackers, with level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.

BackWPup 5 - 5.5.0 - Missing Authorization to Sensitive Information Exposure

Affected versions: 5-5.5.0

Vulnerability type: CWE-862 Missing Authorization

Affected software, patched versions and attribution

The BackWPup – WordPress Backup & Restore Plugin plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'backwpup_working' AJAX action in versions 5 through 5.5.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve access to a back-up's filename while a backup is running. This information has little value on it's own, but could be used to aid in a brute force attack to retrieve back-up contents in limited environments (i.e. NGINX).

BackWPup <= 4.0.1 - Authenticated (Administrator+) Directory Traversal

Affected versions: *-4.0.1

Vulnerability type: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Affected software, patched versions and attribution

The BackWPup plugin for WordPress is vulnerable to Directory Traversal in versions up to, and including, 4.0.1 via the job-specific backup folder. This allows authenticated attackers to store backups in arbitrary folders on the server provided they can be written to by the server. Additionally, default settings will place an index.php and a .htaccess file into the chosen directory (unless already present) when the first backup job is run that are intended to prevent directory listing and file access. This means that an attacker could set the backup directory to the root of another site in a shared environment and thus disable that site.
