Malicious File Upload

Remote code execution in Malcolm (cisagov) prior to version 26.06.1 allows an authenticated user holding the ROLE_UPLOAD role to upload arbitrary PHP files through the FilePond file-upload component and trigger their server-side execution. The file-type allowlist in `file-upload/php/config.php` is an empty array by default, making the type check a no-op; the filename sanitizer further preserves the `.php` extension intact, and nginx routes any URL terminating in `.php` to php-fpm. No public exploit code has been confirmed and Malcolm is not listed in the CISA KEV catalog at time of analysis, but the CVSS 8.8 rating (CWE-434) and straightforward exploitation path make this a genuine priority for any deployment running a pre-26.06.1 release with RBAC enabled.

Unauthenticated credential theft in the InstaWP Connect WordPress migration plugin (all versions ≤ 0.1.3.6) exposes database access details and API signatures on Apache servers during active migration windows. The plugin predictably derives its AES-256-CBC decryption passphrase as SHA256(migrate_key), where the migrate_key is directly leaked in the filename of the unprotected options file via Apache directory listing - allowing an attacker who finds the file to mathematically recover the encryption key and decrypt the options payload without any brute force. Recovery of the api_signature may enable downstream remote code execution via InstaWP's service API. No public exploit or CISA KEV listing has been confirmed at time of analysis, though the deterministic key derivation significantly reduces exploitation effort.

Arbitrary file write in n8n's Edit Image node allows authenticated workflow users to escape the node's designated working directory by injecting unsanitized format parameter values into the underlying image library. All n8n releases before 1.123.67 on the 1.x line, before 2.31.5 on the 2.x line, and before 2.32.1 on the 2.32.x line are affected, as confirmed by the GHSA-xmc9-4f2h-jf9c advisory from the n8n maintainers. No public exploit code has been identified at time of analysis, but patched versions and a remediation commit are available, and no special attacker position beyond workflow execution privileges is required.

Unrestricted file upload in Cockpit CMS versions up to and including 2.6.0 allows any authenticated user to upload PHP scripts via the asset upload endpoint, achieving remote code execution as the web server process. The root cause is the default wildcard (*) value for the allowed_uploads configuration combined with storage of uploaded files in a web-accessible directory - a textbook CWE-434 condition. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the low barrier of entry (any authenticated account) makes this a high-priority remediation target for internet-facing deployments.

Remote code execution in Crafty Controller (crafty-4), a web-based management panel for Minecraft servers, arises from path traversal in the server-import and admin file-upload features that lets an authenticated user write files to arbitrary filesystem paths accessible to the application. By planting a file in an executable or auto-loaded location, a low-privileged authenticated attacker can escalate to code execution in the context of the Crafty Controller process. No public exploit has been identified at the time of analysis, and the issue is not listed in CISA KEV; EPSS data was not provided.

Remote code execution in dulldusk phpfm through 1.8.0 lets an unauthenticated attacker upload a malicious PHP file and run it directly on the server. The application ships insecure-by-default: its upload extension allowlist is empty ($upload_ext_filter = array()) and authentication is off (auth_pass is an empty string), so no credentials or configuration changes are needed to reach the vulnerable upload handler. No public exploit has been identified at time of analysis, but the trivial exploitation path and 9.8 CVSS make this a high-priority server-takeover issue for any exposed instance.

Unauthenticated remote code execution in the Product Input Fields for WooCommerce WordPress plugin before 2.0.2 arises because the plugin skips file-type validation whenever its accepted-types setting is left blank - a configuration the plugin's own documentation advertises as 'accept all files.' Attackers can upload arbitrary files, including PHP webshells, and execute them on servers whose upload directory does not enforce access restrictions. Publicly available exploit code exists (WPScan), though the EPSS score is low (0.20%, 10th percentile) and it is not listed in CISA KEV.

Remote code execution in the Squeeze WordPress plugin (versions prior to 1.7.12) is achievable by any authenticated user holding the upload_files capability - granted by default to the Author role and above. The plugin's attachment-update action writes per-size image data to the uploads directory without validating file type or extension, permitting a PHP webshell to be placed in a web-accessible path and directly invoked via HTTP. A publicly available proof-of-concept exists per WPScan; no public exploit identified at time of analysis in CISA KEV, and EPSS is low at 0.19% (9th percentile), suggesting limited observed in-the-wild exploitation despite the public PoC.

SQL injection in the Iptanus File Upload WordPress plugin (all versions before 5.1.8) enables unauthenticated remote attackers to query the underlying WordPress database without any credentials or user interaction. The CVSS scope-change indicator (S:C) reflects that the injection can reach data beyond the plugin's own tables - including WordPress core tables containing admin password hashes, user emails, and site configuration. No public exploit identified at time of analysis, and EPSS at 0.18% (7th percentile) suggests exploitation has not yet been observed at scale, though the unauthenticated attack surface makes it an attractive target as awareness grows.

Denial of service, and potentially remote code execution, in Tobit Laboratories' David (TeamDavid/Webbox) collaboration suite affects all releases through Rollout 524. Multiple file-upload handlers fail to bounds-check the supplied filename, so an unauthenticated attacker who sends an upload request with an excessively long filename triggers an out-of-bounds stack write (CWE-787) that reliably crashes the server; where the stack layout is favorable or a stack canary can be leaked via a separate flaw, the same overflow may yield code execution and full server compromise. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the flaw was reported by Switzerland's NCSC and detailed by InfoGuard Labs as one of 22 CVEs in David.

Unauthenticated arbitrary file write in Dinky v1.2.5 and its byte-identical development branch lets anyone who can reach the HTTP port (8888 by default) overwrite files as the Dinky service account, because the POST /download/uploadFromRsByLocal handler feeds a caller-supplied path straight into new File(path) and transferTo(dest) with no validation. The route is exempt from Sa-Token auth and guarded only by a header check against a dinkyToken whose default value is hardcoded in source and shipped to every install, so the guard is effectively no guard. The researcher (VulnCheck) demonstrated full remote code execution by shadowing Dinky.class on the writable, chmod-777 classpath and by planting attacker JavaScript in the served index.html; there is no public exploit identified at time of analysis and it is not in CISA KEV, but the disclosure describes a working demonstration.

Unrestricted file upload in ICS-Park Smart Park Management System v2.0 lets a remote attacker upload and execute arbitrary code through the product's file upload module, yielding full server compromise (CVSS 9.8). Public exploit code exists and the flaw is automatable with total technical impact per CISA SSVC, though the EPSS probability remains low at 0.26% (17th percentile), indicating limited observed exploitation activity so far. No CISA KEV listing means no confirmed active exploitation at time of analysis.

Arbitrary file upload in WSO2 API Manager and related Carbon-based products (API Control Plane, Universal Gateway, Traffic Manager) allows an authenticated publisher-privileged user to write attacker-controlled files to arbitrary server-accessible paths via the System REST API, which can escalate to remote code execution depending on how uploaded content is served or executed. The vendor rates it CVSS 9.1 (scope-changed) and a patch is available. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Unauthenticated arbitrary file upload in the Type Hub WordPress plugin (versions ≤ 2.0.6) lets remote attackers upload malicious files without any credentials, typically leading to remote code execution and full site compromise. The CVSS 3.1 base score is a maximum 10.0 with a changed scope (S:C), reflecting that a successful upload can pivot beyond the plugin into the underlying host. No public exploit has been identified at time of analysis and the flaw is not listed in CISA KEV, but the trivial attack complexity and lack of authentication make it an urgent patch priority.

SQL injection in the WordPress File Upload plugin (by nickboss) affects all versions up to and including 5.1.7 and is reachable by unauthenticated remote attackers (CVSS 9.3, AV:N/PR:N). Because the CVSS scope is Changed with high confidentiality impact, a crafted request can coerce the plugin into executing attacker-controlled SQL, exposing WordPress database contents such as user records and secrets. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV; it was reported through Patchstack.

Unauthenticated arbitrary file deletion in the Drag and Drop Multiple File Upload for WooCommerce WordPress plugin (all versions before 1.1.8) lets anonymous attackers destroy customer order attachments staged in the plugin's upload directory. The plugin's only access control on its deletion routine is a nonce, but that nonce can be freely obtained by unauthenticated visitors, defeating the check entirely. Publicly available exploit code exists and a vendor patch has been released; EPSS is low (0.14%) and the issue is not in CISA KEV.

WP-DownloadManager WordPress plugin (all versions prior to 1.69) grants any WordPress administrator holding the manage_downloads capability the ability to achieve full remote code execution by uploading arbitrary PHP files through the unvalidated download-add.php handler. The upload path is additionally constructed from a raw, unsanitized POST parameter, enabling directory traversal into web-accessible locations under WP_CONTENT_DIR where uploaded PHP files execute on direct request. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, but the complete absence of server-side file-type controls and path sanitization makes exploitation trivially simple for any attacker who has obtained admin credentials.

Remote code execution in Pluck CMS through 4.7.21 is achievable by any authenticated administrator who exploits a gap in the file upload blacklist: the extension '.php8' is absent from the hardcoded deny-list in data/inc/files.php, allowing a crafted file to be stored and subsequently executed as PHP on servers running PHP 8.x. Reported by TuranSec, this CWE-434 flaw carries a CVSS 7.2 (PR:H), meaning exploitation is constrained to admin-level accounts but delivers full confidentiality, integrity, and availability impact once triggered. No public exploit code or CISA KEV listing is confirmed at time of analysis, but the bypass is trivially reproducible from the CVE description by any administrator with upload access.

Arbitrary file upload in LightSync Pro WordPress plugin (all versions through 2.1.6) enables authenticated attackers with Author-level access to upload executable files - including PHP webshells - via the unvalidated `rest_replace_media()` REST API function, with remote code execution as a realistic outcome. The root cause is CWE-434: missing file type validation on the server side, allowing any file extension to be accepted. No public exploit code has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the CVSS score of 8.8 reflects the high post-exploitation impact given the minimal privilege bar (Author role).

Remote code execution in the zportals WordPress plugin (all versions before 6.3.4) is achievable by any authenticated user holding a Subscriber role or above, exploiting a server-side file upload validation failure that trusts the client-supplied Content-Type header and preserves the original file extension. By uploading a PHP webshell disguised with a benign MIME type, an attacker can plant executable server-side code and gain full control of the WordPress application layer. A publicly available proof-of-concept exploit exists; no confirmed active exploitation (CISA KEV) has been observed, but the low authentication barrier makes this a genuine risk for sites with open registration.

Remote code execution in Bilin Software HUMANIST Digital Human Resources versions 26.0 through 26.1 allows unauthenticated attackers to upload a web shell to the server due to unrestricted file-type validation (CWE-434), resulting in full compromise of the HR application host. Any remote attacker can reach the upload functionality without credentials or user interaction and execute arbitrary commands. No public exploit identified at time of analysis, though the maximal CVSS 9.8 severity and trivial exploitability make this a high-priority fix for affected deployments.

Unrestricted file upload in freo2 (by refirio) versions prior to 2.0.0-alpha-14 enables highest-privilege administrative users to upload executable files and trigger arbitrary OS command execution on the underlying server. Reported by JPCERT and covered under JVN#52865575, this is a post-authentication code execution path requiring no user interaction once admin access is established. No public exploit code or CISA KEV listing has been identified at time of analysis.

Unauthenticated remote code execution in the Improve SEO WordPress plugin (versions through 2.0.11) lets attackers upload executable PHP files by exploiting a file-upload routine that only validates MIME content type while writing files with the attacker-controlled extension into a web-accessible directory. Any visitor can drop a PHP webshell and execute arbitrary code on the server without credentials or user interaction. Publicly available exploit code exists (reported by WPScan), though the EPSS score is low (0.20%, 10th percentile) and it is not on CISA KEV.

WebsiteBaker CMS before 2.13.10 exposes remote code execution through an unrestricted file upload flaw (CWE-434) in its module installation feature, allowing authenticated administrators to plant a PHP webshell that any unauthenticated internet user can subsequently trigger via direct HTTP request. The CVSS 4.0 vector scores 8.6 with PR:H, reflecting the administrator credential requirement, but the two-phase attack model means post-upload exploitation requires zero authentication. A public proof-of-concept has been published on Medium; the vulnerability is not currently listed in the CISA KEV catalog.

Stack-based buffer overflow in Wavlink's lighttpd-based web interface allows network-adjacent authenticated attackers to achieve arbitrary code execution on at least thirteen SOHO router and range-extender models running firmware through 20260609. The vulnerable code path is the strcpy call within upload.cgi, which copies the HTTP_COOKIE request header into a fixed-size stack buffer without length validation. Publicly available exploit code exists on GitHub (0xcc12138/WAVLINK-vul); no CISA KEV listing is present, but the disclosed POC materially lowers the exploitation barrier for opportunistic actors targeting consumer networking gear.

SQL injection and arbitrary file write in OpenEMR through 8.2.0 expose the full application database to compromise by any user holding admin or super ACL privileges. The backup configuration import feature at backup.php passes uploaded SQL files directly to a shell_exec invocation of the mysql binary without sanitization, enabling unrestricted DDL and DML execution including credential hash extraction, ACL table manipulation, backdoor account injection, and - under permissive MySQL FILE privilege settings - webshell deployment to the filesystem. A publicly available proof-of-concept exists per VulnCheck and a JivaSecurity exploit writeup; no CISA KEV listing is present, so active exploitation is not confirmed, though the low technical barrier post-authentication makes opportunistic insider exploitation realistic.

Remote code execution in the Personal QR Message WordPress plugin (versions through 1.0) allows unauthenticated attackers to upload arbitrary PHP files via a handler that fails to restrict uploaded file types, and those files are directly reachable and executable on the server. Publicly available exploit code exists (published by WPScan), and the CVSS 3.1 base score is 9.8, though the EPSS probability is low at 0.22% (13th percentile). This is a classic unauthenticated file-upload-to-RCE flaw that grants full server compromise with no authentication or user interaction.

Remote code execution in the 'Insert or Embed Articulate Content into WordPress' plugin (versions up to and including 4.3000000027) allows an Editor-level user to upload a server-executable file by defeating a weak archive-content check, then have the web server run it from a public directory. Publicly available exploit code exists (WPScan), and the flaw carries a critical CVSS 9.8; however, EPSS is only 0.21% (11th percentile) and SSVC lists exploitation status as 'none', indicating no confirmed in-the-wild activity yet. The attack is fully automatable with total technical impact once an Editor account is available.

Unauthenticated remote code execution in the Webinfos WordPress plugin (versions through 1.2) lets any anonymous attacker upload arbitrary files - including PHP webshells - because the plugin's upload handler enforces no file-type validation, authentication, capability, or nonce checks. On servers that execute PHP from the uploads directory, this yields full server compromise. Publicly available exploit code exists (reported by WPScan), and while EPSS is currently low at 0.28%, the CVSS 9.8 rating and automatable, unauthenticated nature make this a high-priority patch target.

Unrestricted PHP file upload in the Theme Demo Import WordPress plugin (≤1.1.3) enables administrator-level users - including non-super-admin site admins on multisite installs - to bypass WordPress's native file-type validation and upload executable PHP files to the server's uploads directory, resulting in full remote code execution. A publicly available proof-of-concept exists per WPScan reporting, though EPSS sits at 0.14% (4th percentile), suggesting exploitation remains uncommon. No confirmed active exploitation in CISA KEV; however, SSVC rates technical impact as total.

Unrestricted PHP file upload in Everest Toolkit (WordPress plugin ≤1.2.3) enables authenticated Administrators - including non-super-admin site administrators on multisite networks - to place executable PHP web shells in the wp-content/uploads directory via the demo-content import feature. Full remote code execution on the underlying web server is achievable upon requesting the uploaded file. A publicly available proof-of-concept exists per WPScan; no active exploitation has been confirmed (not in CISA KEV), and EPSS sits at 0.14% (4th percentile), indicating this remains a targeted rather than widespread threat despite total technical impact.

Remote code execution in REDAXO CMS versions 5.18.2 through 5.21.0 is reachable by authenticated backend users with media upload permissions via a multi-segment filename bypass (e.g., shell.php.any.jpg) that defeats the extension blocklist in rex_mediapool::isAllowedExtension. The flaw is a confirmed regression introduced in PR #6213 (February 2025), which replaced a historically correct str_contains guard with weaker str_ends_with logic, reintroducing a double-extension attack class that the codebase had explicitly defended against since 2018. Exploitation additionally requires the target server to run a multi-extension PHP handler (Apache mod_mime AddHandler or unanchored FilesMatch); no public exploit or CISA KEV listing has been identified at time of analysis, and the vendor-released fix is available in version 5.21.1.

Arbitrary file upload in the Realtyna Organic IDX (WPL Real Estate) plugin for WordPress affects all versions up to and including 5.3.0, allowing authenticated attackers with subscriber-level access to write attacker-controlled files to the server and potentially achieve remote code execution. The flaw chains missing extension/content validation in saveLiveImages() with a weak authorization check on the get_keys() AJAX handler and a missing authentication check on the REST API import endpoint. Reported by Wordfence and scored CVSS 8.8; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Unauthenticated remote code execution in the Realtyna Organic IDX / WPL Real Estate WordPress plugin (all versions through 5.2.0) lets attackers upload executable PHP files through the plugin's I/O service. The upload function skips file-type validation, and the endpoint is guarded only by static api_key/api_secret defaults that ship identically in every installation via the plugin's SQL migration files, so any attacker who knows these publicly documented credentials can reach it. Rated CVSS 9.8 by Wordfence; no public exploit identified at time of analysis, but the trivially reproducible preconditions make exploitation straightforward.

Unauthenticated file upload validation bypass in the CodeIgniter4 PHP framework (versions prior to 4.7.4) lets a remote attacker upload executable PHP content by exploiting that the is_image and mime_in strict validation rules never enforced a safe client-supplied filename extension. Applications are affected only when they validate uploads solely with is_image or mime_in (without an independent extension check such as ext_in), persist files under the attacker-controlled client filename, and store them in a web-accessible, script-enabled directory. There is no public exploit identified at time of analysis and the flaw is not on the CISA KEV list; the upstream fix (commit b6e9a4f, released as v4.7.4) adds client-extension consistency checks.

Remote code execution in Wolf CMS through version 0.8.3.1 allows authenticated attackers holding the file_manager_mkfile capability to write arbitrary PHP files into the web-accessible FILES_DIR and execute them by requesting the file over HTTP. The flaw stems from missing file-extension validation in the FileManagerController create_file() and save() functions (CWE-434). Publicly available exploit code exists (via VulnCheck advisory), though it is not listed in CISA KEV; the CVSS 4.0 base score is 8.7 (High).

Remote code execution in the Admin and Site Enhancements (ASE) Pro plugin for WordPress (versions up to and including 8.9.0) allows unauthenticated attackers to run arbitrary PHP on the server. The flaw chains three weaknesses in the frontend custom-form save handler - a publicly emitted nonce with no auth check, a CAPTCHA that is bypassed by simply omitting the attacker-supplied key, and unsanitized repeater-row keys from cfgroup[input] that are spliced directly into an eval() call in recursive_html. Reported by Wordfence; with a CVSS of 9.8 and CWE-434, this is a critical, network-exploitable issue, though no public exploit code or CISA KEV listing has been identified at time of analysis.

Arbitrary file upload in the Balbooa Gridbox page-builder extension for Joomla (versions before 2.20.2) lets an authenticated user upload files of arbitrary type via the extension's file-upload methods, bypassing type restrictions (CWE-434). Uploading executable server-side code (e.g. a PHP web shell) yields authenticated remote code execution, and the vendor rates it CVSS 4.0 9.4 with an 'Attacked' exploit-maturity flag and 'Red' urgency. The impact is materially worse because it chains with CVE-2026-65884, which lets the attacker create the account required to reach the upload feature - collapsing the privilege barrier and effectively enabling attacker-driven RCE. No public exploit is identified at time of analysis, though the CVSS threat metric (E:A) signals the vendor considers exploitation activity present.

Remote code execution in the Extra Checkout Options addon (for Extra Product Options & Add-Ons for WooCommerce) affects all WordPress installs running versions through 2.3.2, letting authenticated Subscriber-level attackers upload PHP web shells. Two flaws chain together: eco_save_settings() lacks authorization and nonce checks so a low-privileged user can add 'php' to the tc_eco_custom_file_types upload allowlist, and the wc_eco_upload_file AJAX action performs insufficient authorization, permitting file upload via the frontend nonce exposed on cart and checkout pages. There is no public exploit identified at time of analysis, but the CVSS 8.8 rating and the fact that only Subscriber access is required make this a serious risk; note the vendor only partially fixed it in 2.3.2.

Arbitrary file upload and remote code execution in Koollab LMS allows an authenticated module designer to achieve full server compromise by uploading a malicious SCORM package containing a PHP webshell. The uploaded file is placed in a publicly accessible directory, enabling the attacker to execute arbitrary commands on the underlying server. No evidence of active exploitation or public exploit code exists at this time, but the CVSS score of 9.9 reflects critical severity.

Arbitrary file upload vulnerability in the Easy Digital Downloads WordPress plugin (≤3.6.9) allows authenticated attackers with Shop Manager-level access to upload malicious files via insufficient validation in the import file upload function, potentially achieving remote code execution. No public exploit or active exploitation reported at time of analysis. The fix was applied in the plugin trunk.

Unauthenticated arbitrary file upload leading to remote code execution exists in Realtyna Organic IDX plugin + WPL Real Estate for WordPress versions before 5.3.0. The file upload API, enabled by default, authenticates using hardcoded credentials identical across all installations and lacks file type validation, allowing attackers to upload and execute PHP files. Publicly available exploit code increases the likelihood of exploitation.

Arbitrary file upload leading to remote code execution affects the WPForms Pro plugin for WordPress in all versions up to and including 1.10.1.1, exploitable by unauthenticated attackers through the ajax_chunk_upload_finalize function. Because file-type validation runs only after chunk metadata and file contents are written to disk, and the assembled file is not removed when validation fails, an attacker can leave an executable payload (e.g. a PHP file) on the server. Reported by Wordfence and tracked as ENISA EUVD-2026-48766, this carries a CVSS 8.1; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Arbitrary command execution in SUNNET Corporate Training Management System through v10.3 allows authenticated administrators to upload a malicious ZIP archive via the e-paper draft upload function. Successful exploitation leads to full server compromise. No public exploit code or active exploitation is known, and EPSS indicates low exploitation probability.

Remote code execution in Bold Reports Standalone Report Designer before 14.1.12 lets authenticated users abuse the file-upload feature to write files outside the intended directory via a crafted filename, ultimately running arbitrary commands with high privileges on the host. The flaw chains a CWE-22 path traversal into server-side command execution, and per the CVSS 4.0 vector requires only low privileges with no user interaction over the network. No public exploit identified at time of analysis, though a VulnCheck advisory documents the issue.

Arbitrary file upload in the Really Simple CSV Importer WordPress plugin (versions <= 1.3) lets an authenticated administrator write files of dangerous types into a web-accessible path, enabling web shell deployment and full site/server compromise. Reported by Patchstack, it carries a CVSS 9.1 (scope-changed) rating, but exploitation requires high privileges (PR:H). There is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Arbitrary file upload in the MapSVG WordPress plugin (versions 8.14.0 and earlier) allows an authenticated administrator to upload files of unrestricted type, enabling execution of attacker-supplied code (e.g. a PHP webshell) on the hosting server. Reported by Patchstack and classified as CWE-434, the flaw carries a CVSS 9.1 owing to a scope change, but the PR:H requirement means only accounts already holding administrator privileges can trigger it. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Arbitrary file upload in the Mailster WordPress email newsletter plugin (versions 4.1.17 and earlier) lets a user with Editor-level privileges upload files of dangerous types, enabling web shell placement and remote code execution on the host. Rated CVSS 9.1 and reported by Patchstack, the flaw abuses insufficient validation in an editor-accessible upload feature; no public exploit identified at time of analysis and it is not listed in CISA KEV.

Unauthenticated arbitrary file upload in the rtCamp GoDAM WordPress plugin (versions ≤ 1.12.2) allows remote attackers to plant executable files and likely achieve remote code execution. The flaw lives in the plugin's WPForms video-field integration, which bypasses WordPress's built-in upload sanitization by trusting the client-supplied Content-Type header and moving raw uploads into a web-served directory. No public exploit code has been identified at time of analysis, but the CVSS 9.8 rating and unauthenticated network vector make this a critical-priority patch for any exposed site.

Authenticated arbitrary file upload in the Page Builder CK extension for Joomla (vendor joomlack.fr) allows a low-privileged authenticated user to upload a malicious file and achieve remote code execution on the host. The flaw (CWE-434) carries a CVSS 4.0 base score of 9.4 driven by high confidentiality, integrity, and availability impact plus subsequent-system impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.

OS command injection in Tenable Security Center (formerly Tenable.sc) lets authenticated users abuse the audit file upload handler, which fails to sanitize filenames and lets shell metacharacters reach a system command call. Rated CVSS 4.0 8.7 (High), the flaw is described as reaching full command execution when chained with a related vulnerability, giving an attacker code execution on the appliance. No public exploit identified at time of analysis, and it is not listed in CISA KEV.

OS command injection in Tenable Security Center (Tenable.sc) lets an authenticated attacker execute arbitrary shell commands by uploading an audit file whose filename contains shell metacharacters, which the application passes unsanitized into a system command. The flaw (CWE-78) carries a CVSS 4.0 base score of 9.4 with high impact to confidentiality, integrity, and availability of both the vulnerable and subsequent systems. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Authenticated remote code execution in FreeScout help desk prior to version 1.8.224 allows any logged-in agent to upload a malicious .pht file that executes as PHP on the default Apache plus libapache2-mod-php stack, yielding arbitrary command execution as the www-data user. The flaw is a denylist bypass: the restricted-extension filter added by the earlier CVE-2025-48471 fix blocked phtml and phar but missed .pht (as well as .phtm and .phps), which Apache's default FilesMatch handler still runs as PHP. No public exploit or CISA KEV listing is identified at time of analysis, but the technique is well understood and low-complexity given a valid agent account.

Unauthenticated file upload in the JDownloads download-manager extension for Joomla allows a remote attacker to place an executable file (e.g. a PHP web shell) on the server and achieve full remote code execution. The flaw affects the JDownloads 4.1 line per the referenced advisory and requires no authentication or user interaction, so any internet-reachable Joomla site running the extension is exposed. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the trivial exploitation profile makes it a high-priority patching target.

Unauthenticated file upload in the DJ-Classifieds extension for Joomla allows remote attackers to upload arbitrary files and achieve full remote code execution on the underlying web server, without any authentication or user interaction. The flaw carries a maximum CVSS 4.0 score of 10.0 and is classified as CWE-434 (unrestricted upload of dangerous file types); a third-party technical write-up (mysites.guru) exists, but no public exploit code or CISA KEV listing has been confirmed at the time of analysis. Any Joomla site running this classifieds/listings extension is exposed to complete server compromise.

Authenticated arbitrary file upload in the ThemeXpert JMedia media-manager extension for Joomla lets an authenticated privileged user (PR:H) write executable files to the server and achieve remote code execution. Uploads accept executable content and polyglot filenames, and the extension's chmod handling fails to strip execute bits, so a planted file can be directly invoked by the web server. Rated CVSS 4.0 9.4 (Critical); no public exploit identified at time of analysis and it is not listed in CISA KEV.

Extension-denylist bypass in the Flask-Reuploaded (flask_uploads) Python library allows an attacker who controls the name override passed to UploadSet.save() to store dangerous script files by varying letter case (e.g. shell.PHP, evil.pHp), defeating the very script-blocking denylist the library documents. This is an incomplete-fix variant of CVE-2026-27641: the v1.5.0 fix re-validated overridden names through the case-preserving extension() helper instead of the case-normalizing lowercase_ext() used by the default path, so uppercase extensions slip past a lowercase-tokened denylist. Publicly available exploit code exists (a self-contained PoC verified against Flask-Reuploaded==1.5.0), though there is no evidence of active exploitation and no EPSS score was provided.

Cross-site request forgery in the Events Booking extension for Joomla (all versions through 5.8.0) lets a remote attacker abuse an unauthenticated frontend file-upload endpoint that lacks anti-CSRF token validation. By luring a logged-in victim to a malicious page, an attacker can force the victim's browser to submit a forged upload request, potentially planting malicious files on the server; the CVSS 3.1 base score is 8.8 with high confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and the EPSS probability is very low (0.10%, 1st percentile).

Remote code execution is possible in the ProfilePress WordPress plugin (Paid Membership, Ecommerce, User Registration) in all versions through 4.16.18, where the DigitalProducts UploadHandler unconditionally registers an upload_mimes filter that whitelists executable extensions (.exe, .apk, .msi) across every WordPress upload context site-wide. Authenticated attackers with author-level access or above (per CVSS PR:L) can leverage this expanded MIME allowlist to upload executable files, leading to code execution. There is no public exploit identified at time of analysis, and this CVE is not listed in CISA KEV.

Unauthenticated arbitrary file upload in Feng Office 3.11.13.11 lets remote attackers push attacker-controlled files (e.g. .html) into the web-accessible /tmp/ directory via the ck_upload_handler.php endpoint, with no authentication or user interaction. A public proof-of-concept exists on GitHub, and the CWE-434 flaw carries a CVSS 9.8, though EPSS remains low (0.46%, 37th percentile) and it is not in CISA KEV, indicating no confirmed in-the-wild abuse yet.

Hardcoded default administrator password in Pheditor (all versions prior to 2.0.6) lets remote unauthenticated attackers log in as admin using the string 'admin' — the SHA-512 hash of which is baked into pheditor.php line 11 — and then abuse the built-in terminal and file-upload features for immediate remote code execution. Any deployment left on defaults is trivially compromised because there is no forced password change, expiry, lockout, or setup wizard. A working PoC is published in the GitHub Security Advisory, though there is no public exploit identified in active in-the-wild campaigns and no EPSS/KEV data is provided.

Remote authenticated code execution in DataEase before 2.10.23 lets a low-privileged user abuse the Excel/datasource upload workflow to run arbitrary Java. By uploading a crafted payload.zip via /datasource/upload and defining an H2 datasource that references the archive through the zip: protocol, an attacker forces CalciteProvider.jdbcFetchResultField to execute a query that triggers precompiled Java aliases embedded in test.mv.db. The vendor CVSS 4.0 vector scores this 7.1 (confidentiality-only), but the underlying primitive is full arbitrary code execution; no public exploit identified at time of analysis and it is not listed in CISA KEV.

Arbitrary code execution in Adobe Commerce, Magento Open Source, Adobe Commerce B2B, and the Adobe Commerce Webhooks Plugin lets a remote attacker run script in the context of a victim's authenticated session by abusing an unrestricted file-upload flaw (CWE-434). Because the impact executes in the current user's browser/session context and requires the victim to visit a crafted URL or compromised page, the outcome is account/session takeover and privilege escalation rather than direct server compromise. There is no public exploit identified at time of analysis and it is not in CISA KEV, but the EPSS score of 28.32% (98th percentile) signals meaningfully elevated exploitation likelihood for a newly disclosed flaw.

Remote code execution in ChurchCRM before 7.4.0 lets an authenticated administrator run arbitrary PHP on the server by installing a plugin ZIP that contains a webshell. Because 'php' is explicitly whitelisted in ALLOWED_EXTENSIONS and the DENIED_EXTENSIONS denylist fails to catch standard .php files, any PHP file inside the archive is extracted directly under the web root and becomes immediately executable over HTTP without the plugin ever being enabled. The /plugins/install-url route additionally allows the archive to be sourced from any attacker-controlled HTTPS URL, validated only against an attacker-supplied SHA-256 hash. No public exploit identified at time of analysis and it is not on CISA KEV.

Remote code execution in the plank/laravel-mediable package before 7.0.0 lets attackers upload a double-extension file such as shell.php.jpg that passes all MIME, extension, and aggregate-type validation because of the trailing .jpg, yet retains an inner .php in its stored basename. On Apache/nginx servers misconfigured to execute any filename containing .php, the stored artifact runs as PHP. Reported by VulnCheck with a vendor patch in 7.0.0; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Remote code execution in ThemisNETPanel (vendor 4real) allows unauthenticated network attackers to fully compromise the underlying server by abusing a file-upload endpoint that lacks any authentication check. An attacker submits a base64-encoded PHP payload, writes it as an arbitrary PHP file, and executes it in the web application's context. Reported by CERT-PL with a CVSS 4.0 base score of 9.3; no public exploit identified at time of analysis and it is not listed in CISA KEV.

Arbitrary file upload in CodeRevolution's Aimogen Pro WordPress plugin (versions up to and including 2.8.3) lets attackers upload files of dangerous types, typically enabling deployment of a PHP web shell and full remote code execution on the host. The supplied CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) rates it 10.0 critical, reflecting network-reachable, low-complexity, unauthenticated exploitation with a scope change. No public exploit identified at time of analysis, and it is not listed in CISA KEV.

Arbitrary file upload in the WoowBot Pro Max WordPress plugin (quantumcloud) through version 14.1.7 allows an authenticated attacker to upload files of dangerous types, leading to remote code execution on the underlying WordPress host. The scope-change CVSS 9.9 reflects that a low-privileged account can pivot to full server compromise. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but Patchstack has confirmed and cataloged the flaw.

Unauthenticated arbitrary file upload in the RSFiles download-manager extension for Joomla (by RSJoomla) lets remote attackers upload executable files (e.g. PHP web shells) and achieve full remote code execution on the hosting server. The CVSS 4.0 threat metrics flag exploitation as active (E:A) and automatable (AU:Y), and NVD/ADP assigns maximum urgency, but no CISA KEV listing was provided in this data. A vendor product page and a third-party technical writeup are referenced; standalone public exploit code was not confirmed in the supplied sources.

Arbitrary file upload in the Phoca Download extension for Joomla lets any authenticated registered user upload executable files (e.g. PHP) that the server will run, yielding full remote code execution. The flaw is scored 9.0 (CVSS 4.0) and is exploitable over the network by low-privilege accounts, so any site permitting self-registration is directly at risk. A public technical write-up describing the RCE technique exists, though no active exploitation has been confirmed by CISA KEV.

Arbitrary file upload in the Swiss Toolkit For WP WordPress plugin (versions ≤ 1.4.6) lets authenticated Author-level (and higher) users bypass file-type validation and upload executable PHP, potentially achieving remote code execution on the host. The flaw stems from the upload_extension_files() function using a substring match instead of a real extension check when the optional 'Enhanced Multi-Format Image Support' feature is enabled. Reported by Wordfence with a CVSS of 8.8; no public exploit identified at time of analysis.

Unauthenticated arbitrary file upload in the Instant Appointment WordPress plugin (all versions ≤ 1.2) lets remote attackers upload files of any type through the 'insapp_upload_image_as_attachment' function, which lacks file-type validation, potentially enabling remote code execution by planting a PHP webshell. Any WordPress site running the plugin is exploitable without authentication or user interaction, matching its 9.8 CVSS rating. No public exploit identified at time of analysis, and the flaw is not in CISA KEV.

Remote code execution in the Post Export Import with Media WordPress plugin (all versions ≤ 1.13.1) is possible because a trailing-dot filename bypass (e.g. 'shell.php.') defeats the extension allow-list in ajax_import_media_start(), letting an administrator-level user smuggle an executable PHP file into the uploads directory during a media import. Reported by Wordfence, the flaw carries CVSS 7.2 and has no public exploit identified at time of analysis; exploitation requires existing administrator (PR:H) access, making it primarily a hardening/defense-in-depth bypass rather than a mass-exploitable entry point.

Unauthenticated remote code execution in the Super Forms - Drag & Drop Form Builder WordPress plugin (all versions through 6.3.313) allows attackers to upload executable files via the nopriv submit_form AJAX handler, which lacks both file-type validation (CWE-434) and any capability check. The plugin's only guardrail is a session nonce, but the companion super_create_nonce nopriv action lets any visitor mint a valid sf_nonce and session cookie on demand, collapsing the attack to two unauthenticated HTTP requests. No public exploit identified at time of analysis, but the CVSS 9.8 rating and trivial exploitability make this a high-priority patch item.

Authenticated remote code execution in docuForm GmbH Client v11.11c lets low-privileged users abuse the report.php file-upload component to run arbitrary code on the server. The flaw combines an authorization-bypass weakness (CWE-639) with unrestricted file upload, so an attacker with any valid account can escalate to full server compromise. No public exploit identified at time of analysis, though a third-party gist referenced in NVD may contain technical write-up material; EPSS is low (0.24%, 15th percentile) and the CVE is not in CISA KEV.

Unauthenticated arbitrary file upload in the Balbooa Forms extension for Joomla lets remote attackers upload executable server-side scripts and achieve full remote code execution. The flaw carries a maximum CVSS 4.0 base score of 10.0 with a scope change, meaning a successful upload compromises the underlying host beyond the vulnerable extension. No public exploit identified at time of analysis, though a third-party write-up (mysites.guru) documents the flaw and the supplied CVSS metadata asserts observed attack activity.

Arbitrary file upload leading to remote code execution affects the premium Blocksy Companion Pro plugin for WordPress in all versions through 2.1.46, where the Custom Fonts extension's flawed MIME validation lets unauthenticated attackers upload executable PHP files disguised as fonts. The Custom Fonts extension registers a wp_check_filetype_and_ext filter that uses strpos() to approve any filename merely containing '.woff2' or '.ttf' anywhere in the string, so a double-extension payload like shell.woff2.php passes as a legitimate font. Reported by Wordfence with a CVSS of 9.8; no public exploit identified at time of analysis and it is not listed in CISA KEV.

Path-equivalence weakness in Progress MOVEit Transfer's File Upload modules lets remote attackers bypass path-normalization checks to reach or place files outside their intended scope, carrying an NVD CVSS of 9.8. It affects MOVEit Transfer before 2025.0.8 and the 2025.1.x line before 2025.1.4, and a vendor patch is available. There is no public exploit identified at time of analysis and EPSS is low (0.25%), while CISA SSVC rates exploitation as none and technical impact as only partial.

OS command injection in the Horde_Vfs_Smb driver of the Horde Virtual File System (VFS) API before 3.0.1 lets authenticated users execute arbitrary shell commands on the server. The flawed _escapeShellCommand() method fails to neutralize shell command-substitution sequences, so attacker-controlled filenames passed through routine file operations are interpolated into a double-quoted /bin/sh -c context and executed via proc_open() before smbclient runs. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but a vendor patch (v3.0.1) exists and the CVSS 4.0 base score is 7.7 (High).

Remote code execution in the Blocksy Companion Pro WordPress plugin (all versions before 2.1.47) lets unauthenticated attackers upload executable PHP files through the Advanced Reviews feature, taking over the site. The save_attachments function relies on a flawed strpos() substring check inherited from the Custom Fonts extension, so a double-extension filename like shell.woff2.php passes validation while the server executes it as PHP. No public exploit has been identified at time of analysis, but a vendor patch (2.1.47) is available and the flaw was reported by VulnCheck.

Arbitrary file upload in the WHMCS Bridge plugin for WordPress (all versions through 6.9) lets authenticated users with Custom-level access or above upload files of any type via the unvalidated connect() function, potentially achieving remote code execution on the host. Reported by Wordfence and tracked as CWE-434, the flaw carries a CVSS of 8.8; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. The impact hinges on the plugin's failure to enforce file-type checks before writing uploaded content to disk.

Remote code execution in the Widget Logic Visual WordPress plugin (all versions through 1.52) lets low-privileged authenticated users run arbitrary PHP on the server. The flaw stems from the widget-logic-update-conditional-tags AJAX action lacking a capability check and nonce verification, allowing any subscriber-and-above account to store attacker-controlled data in the 'nwlv[cod-tag]' parameter that is later passed to an eval() call by widget_logic_visual_check_visibility. Reported by Wordfence with no public exploit identified at time of analysis and no CISA KEV listing.

Remote code execution in DataEase before 2.10.24 allows an authenticated attacker to bypass the prior H2 zip-protocol and file-dropper hardening by uploading a ZIP archive masquerading as a font file (.ttf) via the FontManage.saveFile endpoint, then invoking the H2 database zip protocol against it to execute arbitrary code on the server. The flaw is a regression that defeats an earlier fix, and carries a CVSS 4.0 score of 8.7 (High). No public exploit has been identified at time of analysis, but the vendor GitHub Security Advisory (GHSA-8x36-774q-pwqg) and two remediation commits are published.

Remote code execution in Vtiger CRM before 8.4.0 lets an authenticated low-privileged user upload a malicious .phar file through the Documents module and execute arbitrary PHP. The extension denylist in config.inc.php omits .phar, and a stale Apache 2.2-syntax .htaccess is silently ignored on Apache 2.4, so the payload lands in a web-accessible directory reachable by unauthenticated HTTP - the attack begins authenticated but the final execution step is unauthenticated. Publicly available exploit code exists (published by VulnCheck/Jiva Security); no CISA KEV listing and no EPSS score were provided.

Authenticated remote code execution in Vtiger CRM through version 8.4.0 lets an administrator upload a crafted ZIP archive through the ModuleManager import feature and drop executable PHP files directly into the web-root modules/ directory, yielding a persistent web shell. Because Apache resolves and executes those PHP files before Vtiger's routing layer runs, the resulting shell bypasses the application's authentication entirely and survives independently of the attacker's login session. Publicly available exploit code exists (VulnCheck / Jiva Security), though there is no public exploit identified as being used in active attacks and it is not listed in CISA KEV.

Remote code execution in EGroupware (composer package egroupware/egroupware) lets an authenticated low-privilege user chain an authorization bypass, an arbitrary file write, and an arbitrary file read to fully compromise the server. An attacker forges the participant_role value in a SmallPartMediaRecorder::ajax_upload() request to impersonate a course teacher, then uses path traversal to overwrite header.inc.php with attacker-controlled PHP while preserving a valid file structure recovered via the importexport download read primitive. Where user self-registration is enabled the entire chain can be reached without pre-existing credentials; no public exploit code is identified at time of analysis despite a detailed vendor advisory, and the flaw is not in CISA KEV.

Relative path traversal in the MicroRealEstate file upload functionality lets an authenticated low-privilege user supply crafted filenames containing directory-traversal sequences to write outside the intended upload directory and potentially overwrite system files. All releases through 1.0.0-alpha3 are affected. There is no public exploit identified at time of analysis and the flaw is not listed in CISA KEV; the CVSS 4.0 base score is 7.1, driven primarily by high availability impact.

Remote code execution in the WPFunnels (Funnel Builder for WooCommerce) WordPress plugin versions up to and including 3.12.7 lets attackers write attacker-controlled 'postData' into a PHP-includeable .log file that wpfnl_show_log later renders with include_once, yielding server-side code execution. The initial injection is fully unauthenticated because the nonce guarding the optin endpoint is publicly emitted on every funnel step page, though execution only fires once an administrator opens the poisoned log via the Log Settings View while the 'Enable Logs' toggle is active. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV, but the pre-auth injection combined with a maximal 9.8 CVSS score makes it a high-priority patch for any exposed WooCommerce funnel deployment.

Unrestricted file upload in Esri ArcGIS Server (all versions through 12.0) lets a remote, unauthenticated attacker push arbitrary files to an exposed administrative/upload endpoint, per CVSS PR:N. Esri self-reported the flaw (CWE-434) and rates it critical (CVSS 9.8), and successful upload of an executable payload can lead to full server compromise. There is no public exploit identified at time of analysis, and EPSS is low (0.22%, 13th percentile), indicating it is not yet a mass-exploitation target.

Unauthenticated NoSQL operation hijacking in Apache Camel's camel-mongodb-gridfs component (4.0.0-4.14.7, 4.15.0-4.18.2, 4.19.0-4.20.x) lets a remote HTTP client override the intended GridFS operation and inject MongoDB query documents. When a route bridges an HTTP consumer such as platform-http into a mongodb-gridfs: producer that has no explicit operation set (the default), the raw gridfs.operation, gridfs.objectid and gridfs.metadata headers pass through the HTTP header filter because they lack the Camel/camel prefix, allowing an attacker to turn an intended upload into remove, listAll, or findOne and to inject NoSQL operators. There is no public exploit identified at time of analysis and EPSS is low (0.16%), but CVSS is 9.8 and SSVC rates technical impact as total and automatable.
