CVE-2026-58126 in PACSgear PACS Scan
PACSgear PACS Scan 5.2.1 contains an unauthenticated remote code execution vulnerability that allows remote attackers to read and write arbitrary files by exploiting an exposed .NET Remoting TCP service on port 22222 via PGImageExchQueue.exe without any authentication requirement. Attackers can chain the arbitrary file write primitive with DLL hijacking in PGImageExchangeQueueSvc.exe, which loads missing DLLs such as CRYPTSP.DLL from the application directory, to achieve remote code execution as NT Authority\SYSTEM upon service restart.

CVE-2026-58127 in PACSgear MediaWriter
PACSgear MediaWriter 5.2.1 exposes a .NET Remoting TCP service on port 9000 via PacsgearMediaServerEngine.dll, registered with ObjectURIs RemoteObj and UIRemoteObj, without any authentication requirement. By exploiting the MarshalByRefObject object unmarshalling technique and implementing .NET WebClient class methods, an unauthenticated remote attacker can read and write arbitrary files on the host filesystem. The ObjectURIs are identical across all installations by default. Chaining the arbitrary file write primitive with DLL hijacking opportunities in the MediaWriter service (which runs as NT Authority\\SYSTEM and loads missing DLLs such as CRYPTBASE.DLL from the application directory) enables unauthenticated remote code execution as SYSTEM upon service restart.

Updated Jul 14, 2026
CVE-2026-53422 in Erlang/OTP SSH
Observable Response Discrepancy vulnerability in Erlang OTP ssh (ssh_sftpd module) allows an authenticated SFTP user to enumerate the existence of files and directories outside the configured root directory. The SSH_FXP_REALPATH handler in ssh_sftpd calls relate_file_name/3 with Canonicalize=false, unlike every other SFTP operation handler. This allows .. components in the requested path to bypass the is_within_root/2 check without being resolved. The un-canonicalized path then enters resolve_symlinks/2, which walks up the directory tree above the configured root and issues read_link() syscalls on arbitrary filesystem paths. An authenticated SFTP client can exploit this by sending a REALPATH request with a crafted traversal path. The server response differs depending on whether the target path exists on the host filesystem (SSH_FXP_NAME when the path resolves successfully, SSH_FX_NO_SUCH_FILE when it does not). This creates a path-existence oracle that an attacker can use to enumerate the filesystem structure outside the configured root, including the existence of sensitive files, directories, and mount points. The vulnerability leaks only the existence of paths. No file contents, credentials, or write access are obtainable through this issue alone. The information gained may assist further attacks when combined with other vulnerabilities. This vulnerability is associated with program files lib/ssh/src/ssh_sftpd.erl and program routine ssh_sftpd:handle_op/4. This issue affects OTP from OTP 17.0 until OTP 29.0.3, 28.5.0.3, and 27.3.4.14 corresponding to ssh from 3.0.1 until 6.0.2, 5.5.2.2, and 5.2.11.9.

CVE-2026-24014 iotdb vulnerability
Apache IoTDB DataNode’s internal RPC interface for creating Trigger instances uses the uploaded Trigger JAR name to build a file path without sufficient validation. If the internal DataNode RPC port is exposed to an untrusted network, an attacker may use path traversal sequences in the JAR name to write files outside the intended Trigger installation directory. This could allow arbitrary file write with the permissions of the IoTDB process. This issue affects Apache IoTDB: from 1.3.3 before 2.0.8. Users are recommended to upgrade to version 2.0.8, which fixes the issue.

CVE-2026-49297 apache-airflow-providers-google vulnerability
Apache Airflow's Google provider operators `GCSToSFTPOperator` and `GCSTimeSpanFileTransformOperator` joined GCS object names returned by the bucket listing API directly to a destination filesystem path without normalisation or containment check. A user with write access to the source GCS bucket (typically a different trust principal than the DAG author — partner uploads, ingest-only service accounts, public-data buckets) could create an object whose name contains `..` segments and cause the DAG run to write the downloaded blob outside the configured destination (the SFTP `destination_path` for `GCSToSFTPOperator`; the worker-local temp directory for `GCSTimeSpanFileTransformOperator`), enabling overwrite of arbitrary files on the SFTP server or the worker host. Affects deployments that ingest from buckets writable by less-trusted principals. Users are advised to upgrade to `apache-airflow-providers-google` 22.2.1 or later.

CVE-2026-58403 hugo vulnerability
Hugo is a static site generator. From v0.123.0 through v0.163.0, Hugo's virtual filesystem is designed so that files under a mount cannot reach outside the mount tree, but a regression caused RootMappingFs.statRoot to call Stat, which follows symlinks, instead of Lstat, so a direct os.ReadFile "somefile" where somefile was a symlink pointing outside the mount would return the target's contents. This effectively let a symlink planted inside a theme or local mount read arbitrary files reachable to the user running hugo. This issue is fixed in v0.163.1.
Updated Jul 13, 2026
CVE-2026-50135 hugo vulnerability
Hugo is a static site generator. From 0.123.0 to 0.161.1, a regression made RootMappingFs.statRoot use Stat (follows symlinks) instead of Lstat , so a direct resources.Get of a symlink pointing outside its mount returned the target's contents — letting a symlink planted in a local mount (e.g. a vendored themes/ theme) read arbitrary files accessible to the Hugo user. Go-module themes from GitHub (symlinks stripped) and directory walks were unaffected. Fixed in 0.162.0.

CVE-2026-57571 crawl4ai vulnerability
Crawl4AI is an open-source LLM-friendly web crawler and scraper. Prior to 0.9.0, when the crawler saves a downloaded file, the destination filename was taken from attacker-influenced input and joined to the downloads directory with no confinement. A filename containing an absolute path or traversal escaped the downloads directory, giving an arbitrary file write with attacker-controlled contents; the HTTP crawler path uses the response Content-Disposition filename and the browser crawler path uses the download's suggested filename. Because the written bytes are attacker-controlled, this can escalate to remote code execution. This issue is fixed in version 0.9.0.
Updated Jul 13, 2026
CVE-2026-39245 decompress vulnerability
decompress before 4.2.2 contains an improper path containment check that enables directory traversal and arbitrary file write. The safeMakeDir function (index.js line 29) and the extraction path validation (index.js line 106) use String.indexOf() to verify the resolved path is within the output directory: realDestinationDir.indexOf(realOutputPath) !== 0. This check is flawed because it does not enforce a path separator boundary. For example, "/tmp/app_config".indexOf("/tmp/app") returns 0, incorrectly passing the check even though /tmp/app_config is outside /tmp/app. Combined with the unvalidated symlink creation in the same package, an attacker can write arbitrary files to directories adjacent to the extraction target. This is a bypass of the fix for CVE-2020-12265. The correct check requires appending a path separator: realParentPath.indexOf(realOutputPath + path.sep) !== 0.

AR for WooCommerce <= 8.40 - Unauthenticated Path Traversal to Arbitrary File Read via 'file' Parameter
The AR for WooCommerce plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 8.40 via the 'file' parameter parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. The three intended access controls all fail: valid nonces are freely minted by unauthenticated callers via the nopriv ar_get_fresh_nonce and ar_process_user_image AJAX handlers; the AES-256-CBC encryption key is derived from get_option('ar_licence_key'), which returns false on default free installations and yields a predictable key attackers can use to encrypt their own path payloads; and the Referer check is trivially bypassed because the Referer header is attacker-controlled.

Perfmatters <= 2.6.4 - Unauthenticated Arbitrary File Read via 's' Parameter
The Perfmatters plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.6.4 via the 's' parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Exploitation requires the Local Google Fonts feature to be enabled (disabled by default), pretty permalinks to be active, and RSS feed links to remain enabled in the plugin settings.

Database for Contact Form 7, WPforms, Elementor forms <= 1.5.1 - Unauthenticated Arbitrary File Copy/Upload via Elementor Pro Form Upload Field 'raw_value'
The Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress is vulnerable to Arbitrary File Copy via the create_entry_el() function in versions up to, and including, 1.5.1. The function reads raw_value from Elementor Pro's Form_Record object for upload-type fields and passes it directly to PHP's copy() without validating that the value corresponds to a legitimately uploaded file — when no file is present in $_FILES, raw_value reflects the attacker-controlled POST string. copy() accepts both local filesystem paths and URL sources, so the attacker can target any file readable by the PHP process or supply an attacker-controlled remote URL. Elementor Pro is a prerequisite for triggering the code path (it owns the elementor_pro/forms/new_record hook and populates the Form_Record object), but the bug itself is entirely in Contact Form Entries' handler. This could allow unauthenticated attackers to disclose arbitrary files on the affected site's server. The file is copied to a directory unknown to the attacker; the hashed directory name provides defense-in-depth but is generated from non-cryptographic sources (uniqid() + rand()) and should not be relied upon as the primary mitigation.

Printcart Web to Print Product Designer for WooCommerce <= 2.5.2 - Unauthenticated Arbitrary File Deletion
The Printcart Web to Print Product Designer for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 2.5.2 This is due to insufficient path validation in the store_design_data() function, which constructs a filesystem path from the user-supplied 'nbd_item_key' POST parameter sanitized only with sanitize_text_field() — which does not strip path traversal sequences — and then passes that path directly to Nbdesigner_IO::delete_folder() and PHP's rename(). The nonce protecting the nbd_save_customer_design AJAX action is freely obtainable by unauthenticated users via the nbd_check_use_logged_in endpoint. This makes it possible for unauthenticated attackers to delete arbitrary files on the affected site's server which may make remote code execution possible.
