Algernon: handler.lua discovery walks parent directories above the server root

Algernon is a small self-contained pure-Go web server. Prior to 1.17.7, when Algernon is asked for any URL path that resolves to a directory without an index file, DirPage walks upward through parent directories — past the configured server root — looking for a file named handler.lua to execute as the request handler. The loop terminates only after 100 ancestor steps or when filepath.Dir returns ., so on any absolute server-root path the search reaches the filesystem root (/ on Unix, drive letter on Windows). The first handler.lua it finds is loaded into the Lua interpreter with the full Algernon API exposed — including run3(), httpclient, os.execute, io.popen, PQ, MSSQL, raw filesystem access, and the userstate database. Any process that can write handler.lua anywhere in a parent directory of the server root obtains pre-authenticated remote code execution on the next HTTP request. This is reachable without authentication — the lookup happens before the permission check returns a hit (the perm system only gates URL prefixes, not the handler-resolution step), and any URL pointing at a directory without an index triggers the walk. On a fresh stock Algernon install the request GET / is enough. This vulnerability is fixed in 1.17.7.

Unauthorized Arbitrary File Deletion via ElasticSearch in Nexent v1.7.5.2

The nexent v1.7.5.2 backend service contains an unauthorized arbitrary file deletion vulnerability in its ElasticSearch service interface. The DELETE /{index_name}/documents endpoint lacks proper authentication and authorization controls and does not validate the user-supplied path_or_url parameter. This allows unauthenticated remote attackers to send crafted requests that trigger the deletion of arbitrary documents from ElasticSearch indices and corresponding files from the MinIO storage system. Successful exploitation leads to data destruction and denial of service.

Unauthorized Deletion of Files via Backend REST API

The nexent v1.7.5.2 backend service contains an unauthorized arbitrary storage file deletion vulnerability in its file management API. The DELETE /storage/{object_name:path} endpoint lacks authentication, authorization, and input validation mechanisms. Unauthenticated remote attackers can send crafted requests with a user-controlled object_name path parameter to delete arbitrary files from the underlying MinIO storage system. Successful exploitation leads to data loss and denial of service.

pgAdmin 4: Local file inclusion and server-side request forgery in LLM API configuration endpoints

Local file inclusion (LFI) and server-side request forgery (SSRF) vulnerabilities in pgAdmin 4 LLM API configuration endpoints. User-supplied api_key_file and api_url preferences were passed to the LLM provider clients without validation. An authenticated user could read arbitrary server-side files by pointing api_key_file at any path readable by the pgAdmin process, or coerce pgAdmin into making requests to internal targets (e.g. cloud metadata services such as 169.254.169.254) by setting api_url, exploiting the chat path and model-list endpoints. Fix restricts api_key_file to the user's private storage (server mode) or home directory (desktop mode), enforces a printable-ASCII key shape and a 1024-byte read cap, and gates api_url against a configurable allow-list (config.ALLOWED_LLM_API_URLS) at every entry point. This issue affects pgAdmin 4: before 9.15.

Microsoft Word Information Disclosure Vulnerability

Files or directories accessible to external parties in Microsoft Office Word allows an unauthorized attacker to disclose information locally.

Crypt::DSA versions through 1.19 for Perl use 2-args open, allowing existing files to be modified

Crypt::DSA versions through 1.19 for Perl use 2-args open, allowing existing files to be modified.

iControl SOAP vulnerability

A vulnerability exists in iControl SOAP where an authenticated attacker with the Resource Administrator or Administrator role can download sensitive files.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

BIG-IP iControl SOAP vulnerability

An authenticated attacker with the Resource Administrator or Administrator role can modify configuration objects through iControl SOAP resulting in privilege escalation.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Microsoft Teams Spoofing Vulnerability

Files or directories accessible to external parties in Microsoft Teams allows an unauthorized attacker to perform spoofing locally.

Path Handling Vulnerability Allows Unauthorized Observation of User Data

A path handling issue was addressed with improved logic. This issue is fixed in macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5. An app may be able to observe unprotected user data.

PaperCut NG/MF: Path Traversal in Shared Account Synchronization

An issue was discovered in the Shared Account Synchronization component of PaperCut MF (version 25.0.4). The application allows administrative users to configure a source path for account data synchronization. Due to a lack of proper path validation and sanitization, an authenticated user with administrative privileges can specify arbitrary file paths on the local file system. This allows for the enumeration of directory structures and the unauthorized reading of sensitive text-based configuration or system files. When the synchronization process is triggered, the application attempts to parse the contents of the specified file, subsequently exposing the data within the application's account management interface. This vulnerability could lead to the disclosure of sensitive system information or configuration details, depending on the permissions of the service account under which the application is running.

ELECOM wireless LAN routers allow a network-adjacent unauthenticated attacker to obtain the configuration file containing sensitive information by sending a specially crafted request.

Magic Export & Import < 1.2.0 - Unauthenticated PII Disclosure

The Magic Export & Import WordPress plugin before 1.2.0 stores exported CSV files at a publicly accessible location, making it possible for any visitors to leak sensitive user information.

Unauthenticated Directory Exposure in Pro-Bit Prior to v1.77.4

An issue in Pro-Bit before v1.77.4 allows unauthenticated attackers to directly access sensitive directory and its subdirectories.

code-projects Online Food Ordering System localhost.sql privilege escalation

A weakness has been identified in code-projects Online Food Ordering System 1.0. This affects an unknown part of the file /dbfood/localhost.sql. This manipulation causes files or directories accessible. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. It is advisable to modify the configuration settings.

CF Image Hosting Script 1.6.5 Unauthorized Database Access

CF Image Hosting Script 1.6.5 allows unauthenticated attackers to download and decode the application database by accessing the imgdb.db file in the upload/data directory. Attackers can extract delete IDs stored in plaintext from the deserialized database and use them to delete all pictures via the d parameter.

Digitaldesign CMS 0.1 stores sensitive information under the web root with insufficient access control, which allows remote attackers to download the database file via a direct request for autoconfig.dd.

Import WP – Export and Import CSV and XML files to WordPress <= 2.14.17 - Unauthenticated Information Exposure

The Import WP – Export and Import CSV and XML files to WordPress plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.14.17 via the import/export functionality and a lack of .htaccess protection. This makes it possible for unauthenticated attackers to extract sensitive data from exports stored in /exportwp and import data stored in /importwp.

ImageMagick: File deletion

The EPHEMERAL coder in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allows remote attackers to delete arbitrary files via a crafted image.

LORIS has potential cross-site scripting in help_editor module

LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. From to before 27.0.3 and 28.0.1, the help_editor module of LORIS did not properly sanitize some user supplied variables which could result in a reflected cross-site scripting attack if a user is tricked into following an invalid link. The same input vector could also allow an attacker to download arbitrary markdown files on an unpatched server. This vulnerability is fixed in 27.0.3 and 28.0.1.
