CVE-2026-8118 (GCVE-0-2026-8118)

Title
Royal Addons for Elementor – Addons and Templates Kit for Elementor 1.7.1058 - 1.7.1059 - Authenticated (Contributor+) Arbitrary File Read via Data Table Widget CSV File Source
Summary
The Royal Addons for Elementor – Addons and Templates Kit for Elementor plugin for WordPress is vulnerable to Arbitrary File Read in versions 1.7.1058 through 1.7.1059. This is due to the wpr_get_csv_handle() helper (introduced in version 1.7.1058 as part of the patch for CVE-2026-6229) falling back to is_readable() and fopen($source, 'r') on the attacker-controlled settings.table_upload_csv.url value when it does not parse as an HTTP URL, with no allow-list, traversal block, or extension check. This makes it possible for authenticated attackers, with Contributor-level access and above, to save a crafted wpr-data-table widget through Elementor's save_builder endpoint and have the rendered preview return the line-by-line contents of any file readable by the PHP process, including wp-config.php.

CVE-2026-8095 (GCVE-0-2026-8095)

Vulnerability from cvelistv5 – Published: 2026-06-27 23:28 – Updated: 2026-06-29 13:51

Title
Frontend File Manager Plugin <= 23.6 - Authenticated (Subscriber+) Arbitrary File Deletion
Summary
The Frontend File Manager Plugin plugin for WordPress is vulnerable to Authenticated Arbitrary File Deletion in versions up to and including 23.6. This is due to a case-sensitive bypass of the wpfm_dir_path parameter sanitization in the wpfm_file_meta_update AJAX handler, where supplying WPFM_DIR_PATH in uppercase evades the unset check and is normalized to wpfm_dir_path by sanitize_key() during update_post_meta(), allowing an attacker to overwrite the stored file path with an arbitrary filesystem path that is then passed directly to unlink() in delete_file_locally() without any directory containment validation. This makes it possible for authenticated attackers with Subscriber-level access to delete arbitrary files on the server, including sensitive files such as wp-config.php, potentially leading to full site takeover.

CVE-2026-6101 (GCVE-0-2026-6101)

Title
AMP for WP <= 1.1.12 - Authenticated (Author+) Arbitrary File Write via Role-Based Access Configuration with Local Font Upload
Summary
The AMP for WP – Accelerated Mobile Pages plugin for WordPress is vulnerable to Arbitrary File Write in versions up to and including 1.1.12. This is due to unsafe ZIP file extraction in the ampforwp_save_local_font() function combined with inadequate cleanup that fails to remove nested directories and files. This makes it possible for authenticated attackers, with Author-level access and above, and permissions granted by an Administrator, to write arbitrary files to the server in a web-accessible location, potentially leading to remote code execution on hosts that execute PHP files in the uploads directory.

Title
WP-BusinessDirectory <= 4.0.1 - Unauthenticated Arbitrary File Deletion via Path Traversal via '_filename' Parameter
Summary
The WP-BusinessDirectory plugin for WordPress is vulnerable to Unauthenticated Arbitrary File Deletion in versions up to and including 4.0.1. This is due to insufficient path validation in the remove() method of the JBusinessDirectoryControllerUpload class. The task=upload.remove endpoint is accessible without authentication via the plugin's frontend routing system. The _filename parameter is accepted with RAW filter (no sanitization), and the helper function makePathFile() only normalizes directory separator characters without stripping path traversal sequences (../). When combined with the _path_type=2 parameter, which sets the base directory to the plugin's site folder, an attacker can supply a _filename value containing ../ sequences to traverse outside the plugin directory and call PHP's unlink() on arbitrary files — including wp-config.php, wp-config-backup.php, or other critical server files accessible to the web server process. This makes it possible for unauthenticated attackers to delete arbitrary files on the server.

Title
Image Optimizer <= 1.7.4 - Authenticated (Author+) Arbitrary File Deletion via Post Meta Field Injection
Summary
The Image Optimizer plugin for WordPress is vulnerable to arbitrary file deletion in versions up to and including 1.7.4. This is due to insufficient path validation in the Image_Backup::remove() function where backup file paths stored in post meta are used directly in file deletion operations without verifying they are within the uploads directory. The plugin stores backup file paths in the image_optimizer_metadata post meta field and trusts these paths completely when deleting backups on the delete_attachment hook. An authenticated attacker with Author-level access can edit the image_optimizer_metadata post meta on their own attachments via WordPress's Custom Fields interface, injecting arbitrary absolute file paths into the backups array. When the attacker subsequently deletes the attachment, the plugin calls File_System::delete() on each path without validation. This makes it possible for authenticated attackers, with Author-level access and above, to delete arbitrary files on the server within the web server's filesystem permissions, potentially leading to denial of service, data loss, or security degradation.

CVE-2026-5809 (GCVE-0-2026-5809)

Title
wpForo Forum <= 3.0.2 - Authenticated (Subscriber+) Arbitrary File Deletion via 'data[body][fileurl]' Parameter
Summary
The wpForo Forum plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to and including 3.0.2. This is due to a two-step logic flaw: the topic_add() and topic_edit() action handlers accept arbitrary user-supplied data[*] arrays from $_REQUEST and store them as postmeta without restricting which fields may contain array values. Because 'body' is included in the allowed topic fields list, an attacker can supply data[body][fileurl] with an arbitrary file path (e.g., wp-config.php or an absolute server path). This poisoned fileurl is persisted to the plugin's custom postmeta database table. Subsequently, when the attacker submits wpftcf_delete[]=body on a topic_edit request, the add_file() method retrieves the stored postmeta record, extracts the attacker-controlled fileurl, passes it through wpforo_fix_upload_dir() which only rewrites legitimate wpforo upload paths and returns all other paths unchanged, and then calls wp_delete_file() on the unvalidated path. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files writable by the PHP process on the server, including critical files such as wp-config.

This is due to a two-step logic flaw: the topic_add() and topic_edit() action handlers accept arbitrary user-supplied data[*] arrays from $_REQUEST and store them as postmeta without restricting which fields may contain array values. Because \u0027body\u0027 is included in the allowed topic fields list, an attacker can supply data[body][fileurl] with an arbitrary file path (e.g., wp-config.php or an absolute server path). This poisoned fileurl is persisted to the plugin\u0027s custom postmeta database table. Subsequently, when the attacker submits wpftcf_delete[]=body on a topic_edit request, the add_file() method retrieves the stored postmeta record, extracts the attacker-controlled fileurl, passes it through wpforo_fix_upload_dir() which only rewrites legitimate wpforo upload paths and returns all other paths unchanged, and then calls wp_delete_file() on the unvalidated path. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files writable by the PHP process on the server, including critical files such as wp-config."

Title
NoMachine External Control of File Path Local Privilege Escalation Vulnerability
Summary
NoMachine External Control of File Path Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of NoMachine. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of command line parameters. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-28630.

Mitigation
Architecture and Design

When the set of filenames is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames, and reject all other inputs. For example, ID 1 could map to "inbox.txt" and ID 2 could map to "profile.txt". Features such as the ESAPI AccessReferenceMap provide this capability.

Mitigation
Architecture and Design Operation
  • Run your code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict all access to files within a particular directory.
  • Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection.
  • This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise.
  • Be careful to avoid CWE-243 and other weaknesses related to jails.
Mitigation
Architecture and Design

For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.

Mitigation MIT-5.1
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • When validating filenames, use stringent allowlists that limit the character set to be used. If feasible, only allow a single "." character in the filename to avoid weaknesses such as CWE-23, and exclude directory separators such as "/" to avoid CWE-36. Use a list of allowable file extensions, which will help to avoid CWE-434.
  • Do not rely exclusively on a filtering mechanism that removes potentially dangerous characters. This is equivalent to a denylist, which may be incomplete (CWE-184). For example, filtering "/" is insufficient protection if the filesystem also supports the use of "\" as a directory separator. Another possible error could occur when the filtering is applied in a way that still produces dangerous data (CWE-182). For example, if "../" sequences are removed from the ".../...//" string in a sequential fashion, two instances of "../" would be removed from the original string, but the remaining characters would still form the "../" string.
Mitigation
Implementation

Use a built-in path canonicalization function (such as realpath() in C) that produces the canonical version of the pathname, which effectively removes ".." sequences and symbolic links (CWE-23, CWE-59).

Mitigation
Installation Operation

Use OS-level permissions and run as a low-privileged user to limit the scope of any successful attack.

Mitigation
Operation Implementation

If you are using PHP, configure your application so that it does not use register_globals. During implementation, develop your application so that it does not rely on this feature, but be wary of implementing a register_globals emulation that is subject to weaknesses such as CWE-95, CWE-621, and similar issues.

Mitigation
Testing

Use tools and techniques that require manual (human) analysis, such as penetration testing, threat modeling, and interactive tools that allow the tester to record and modify an active session. These may be more effective than strictly automated techniques. This is especially the case with weaknesses that are related to design and business rules.

CAPEC-13: Subverting Environment Variable Values

The adversary directly or indirectly modifies environment variables used by or controlling the target software. The adversary's goal is to cause the target software to deviate from its expected operation in a manner that benefits the adversary.

CAPEC-267: Leverage Alternate Encoding

An adversary leverages the possibility to encode potentially harmful input or content used by applications such that the applications are ineffective at validating this encoding standard.

CAPEC-64: Using Slashes and URL Encoding Combined to Bypass Validation Logic

This attack targets the encoding of the URL combined with the encoding of the slash characters. An attacker can take advantage of the multiple ways of encoding a URL and abuse the interpretation of the URL. A URL may contain special character that need special syntax handling in order to be interpreted. Special characters are represented using a percentage character followed by two digits representing the octet code of the original character (%HEX-CODE). For instance US-ASCII space character would be represented with %20. This is often referred as escaped ending or percent-encoding. Since the server decodes the URL from the requests, it may restrict the access to some URL paths by validating and filtering out the URL requests it received. An attacker will try to craft an URL with a sequence of special characters which once interpreted by the server will be equivalent to a forbidden URL. It can be difficult to protect against this attack since the URL can contain other format of encoding such as UTF-8 encoding, Unicode-encoding, etc.

CAPEC-72: URL Encoding

This attack targets the encoding of the URL. An adversary can take advantage of the multiple way of encoding an URL and abuse the interpretation of the URL.

CAPEC-76: Manipulating Web Input to File System Calls

An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

CAPEC-78: Using Escaped Slashes in Alternate Encoding

This attack targets the use of the backslash in alternate encoding. An adversary can provide a backslash as a leading character and causes a parser to believe that the next character is special. This is called an escape. By using that trick, the adversary tries to exploit alternate ways to encode the same character which leads to filter problems and opens avenues to attack.

CAPEC-79: Using Slashes in Alternate Encoding

This attack targets the encoding of the Slash characters. An adversary would try to exploit common filtering problems related to the use of the slashes characters to gain access to resources on the target host. Directory-driven systems, such as file systems and databases, typically use the slash character to indicate traversal between directories or other container components. For murky historical reasons, PCs (and, as a result, Microsoft OSs) choose to use a backslash, whereas the UNIX world typically makes use of the forward slash. The schizophrenic result is that many MS-based systems are required to understand both forms of the slash. This gives the adversary many opportunities to discover and abuse a number of common filtering problems. The goal of this pattern is to discover server software that only applies filters to one version, but not the other.

CAPEC-80: Using UTF-8 Encoding to Bypass Validation Logic

This attack is a specific variation on leveraging alternate encodings to bypass validation logic. This attack leverages the possibility to encode potentially harmful input in UTF-8 and submit it to applications not expecting or effective at validating this encoding standard making input filtering difficult. UTF-8 (8-bit UCS/Unicode Transformation Format) is a variable-length character encoding for Unicode. Legal UTF-8 characters are one to four bytes long. However, early version of the UTF-8 specification got some entries wrong (in some cases it permitted overlong characters). UTF-8 encoders are supposed to use the "shortest possible" encoding, but naive decoders may accept encodings that are longer than necessary. According to the RFC 3629, a particularly subtle form of this attack can be carried out against a parser which performs security-critical validity checks against the UTF-8 encoded form of its input, but interprets certain illegal octet sequences as characters.
