CWE-643: XPath Injection vulnerabilities

CVE-2026-93434 is an XPath injection vulnerability in WatchGuard Fireware OS affecting the SSH authentication process. It allows a remote, unauthenticated attacker with access to the management SSH interface to extract sensitive configuration data by submitting specially crafted requests. The vulnerability affects multiple versions prior to 12.5.22, 2026.4, and 12.12.4. It has a high severity score of 8.7 and has been officially fixed in the specified versions.

CVE-2026-58395 is an XPath Injection vulnerability in the OPNsense core firewall and routing platform prior to version 26.1.11. It allows a user with certain module privileges to send crafted tokens to delete endpoints, causing XPath expressions to expose configuration data across multiple modules without modifying the configuration. The issue is fixed in version 26.1.11.

CVE-2026-53582 is an XML Injection vulnerability in the OPNsense core Trust module prior to version 26.1.10. It allows users with CA Manager or Certificate Manager privileges to inject crafted refid values into XPath expressions, enabling them to recover sensitive configuration data character by character. Exposed data may include password hashes, API credentials, private keys, and VPN key material, potentially leading to privilege escalation and compromise of other security domains. The issue is fixed in OPNsense version 26.1.10.

IBM Cloud Pak for Business Automation 26.0.0 through 26.0.0 Interim Fix 001, 25.0.0 through 25.0.0 Interim Fix 005, 24.0.1 through 24.0.1 Interim Fix 008, and 24.0.0 through 24.0.0 Interim Fix 009 is vulnerable to an XPath injection vulnerability, which could allow an authenticated attacker to exfiltrate sensitive application data and/or determine the structure of the XML document.

XML::Sig versions before 0.71 for Perl are vulnerable to XPath injection due to improper neutralization of data within XPath expressions. The vulnerability arises because the verify() and _get_signed_xml() functions build XPath queries by concatenating unescaped URI values from the document, allowing an attacker to inject arbitrary XPath operators. This can cause the digest verification process to select unintended XML nodes, potentially compromising the integrity verification of signed XML documents.

Plesk contains an XPath injection vulnerability in the APS Application Catalog search functionality, where user-supplied input is interpolated into XPath queries without proper sanitization. This allows an authenticated, low-privileged user to execute arbitrary operating system commands on the server, resulting in local privilege escalation.

A vulnerability exists in the undisclosed pages in the Configuration utility that may allow a low-privileged authenticated attacker to access to undisclosed sensitive information.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Improper Neutralization of Data within XPath Expressions ('XPath Injection') vulnerability in Apache HertzBeat. This issue affects Apache HertzBeat: from 1.7.1 before 1.8.0. Users are recommended to upgrade to version 1.8.0, which fixes the issue.

CVE-2025-11844 is an XPath injection vulnerability in Hugging Face's Smolagents version 1.20.0, specifically in the search_item_ctrl_f function. The vulnerability arises from unsanitized user input being directly concatenated into XPath queries, allowing attackers to manipulate query logic. Exploitation can bypass search filters, access unintended DOM elements, and disrupt automated web tasks, potentially leading to information disclosure and manipulation of AI agent interactions. The flaw is fixed in version 1.22.0. The CVSS score is 5.4 (medium severity), with no known exploits in the wild.
