Vulnerabilities

GitHub MCP Server is GitHub's official MCP Server. Prior to 1.1.0, the CompletionsHandler function in pkg/github/server.go accesses params.Ref without first checking whether it is nil, so a completion/complete request with a missing or empty ref field triggers a nil pointer dereference and a Go runtime panic; because the crash occurs before any authentication or token validation, any unauthenticated client able to send JSON-RPC messages can crash the server, resulting in a complete denial of service. This issue is fixed in version 1.1.0.

WordPress Coding Standards is a set of PHP_CodeSniffer rules (sniffs) that enforce WordPress coding conventions. From 0.14.1 until 3.4.1, the WordPress.WP.EnqueuedResourceParameters sniff (active in the WordPress and WordPress-Extra rulesets) reconstructed the $ver argument passed to functions such as wp_enqueue_script() and ran it through eval() inside its is_falsy() method, so a maliciously crafted argument such as 'system'('id') would execute during a scan; as a result, running PHPCS with WordPressCS over untrusted PHP (for example a CI pipeline that lints pull requests, or a developer reviewing third-party code) could lead to arbitrary command execution on the scanning host. The WordPress-Core and WordPress-Docs rulesets are not affected. This issue is fixed in version 3.4.1.

Appium Java Client is the Java language binding for writing Appium tests that conform to the W3C WebDriver protocol. From 8.2.1 until 10.1.1, when directConnect(true) is enabled, AppiumCommandExecutor.setDirectConnect() reads the directConnectHost, directConnectPort, and directConnectPath fields from the server's NEW_SESSION response and rebuilds the client's server URL from them, validating only that the protocol is https, with no host allowlist or IP validation; a rogue or compromised server can therefore redirect all subsequent session traffic to an arbitrary destination, enabling full interception of session traffic and a server-side request forgery pivot to internal hosts, including cloud metadata (IMDS) credential theft. This vulnerability is fixed in 10.1.1.

Uncontrolled Search Path Element vulnerability in ArkSigner Software and Hardware Industry and Trade Inc. ArkSigner Desktop Client allows Search Order Hijacking.<br /> <br /> This issue affects ArkSigner Desktop Client: from v2.2.16.10 through 17062026.

Mattermost versions 11.8.x

Pivotick contains a DOM-based cross-site scripting vulnerability in its generic UI element resolution and icon-rendering utilities.<br /> <br /> The tryResolveHTMLElement function treated any resolved string as HTML markup by assigning it to a element through innerHTML. Strings derived from untrusted graph properties or custom rendering callbacks could therefore introduce arbitrary HTML or SVG elements into the live document. The vulnerable function was used by multiple UI components, including headers, property panels, extra panels, and tooltips.<br /> <br /> Additionally, createIcon inserted caller-supplied svgIcon markup into a template without sanitization. An application integrating Pivotick and deriving icon markup from untrusted data could therefore expose a second script-execution path.<br /> <br /> An unauthenticated attacker able to provide a crafted graph, property value, rendering result, or SVG icon could execute JavaScript in another user&amp;#39;s browser when the affected content is displayed or interacted with. Successful exploitation could allow the attacker to access information available to the victim, manipulate graph data or application state, and perform actions with the victim&amp;#39;s privileges.<br /> <br /> The patch changes string rendering to use textContent, requiring callers to explicitly return an Element when HTML rendering is intended. It also sanitizes SVG icon markup before inserting it into the DOM.

MISP installation scripts generated an Apache HTTP virtual-host configuration containing an incorrectly formatted HTTP-to-HTTPS redirect:<br /> <br /> Redirect permanent / https://misp.example<br /> <br /> Apache’s Redirect directive appends any portion of the requested path that follows the matched prefix to the configured destination URL. Because the destination did not end with /, attacker-controlled path content was appended directly to the hostname rather than to its URL path.<br /> <br /> For example, a request resembling:<br /> <br /> http://misp.example/@attacker.example/<br /> <br /> could result in a redirect resembling:<br /> <br /> https://misp.example@attacker.example/<br /> <br /> Under standard URL parsing, misp.example is interpreted as user information and attacker.example as the destination host. An unauthenticated remote attacker could therefore construct a URL hosted under the legitimate MISP domain that redirects users to an attacker-controlled website.<br /> <br /> The vulnerability could be used for phishing, credential collection, or potentially disclosing sensitive query-string information preserved during the redirect. Exploitation requires a user to follow the crafted HTTP URL.<br /> <br /> The fix adds the missing trailing slash to the redirect destination, ensuring that appended request data remains part of the path on the configured MISP host.<br /> <br /> <br /> <br /> Existing installationsExisting MISP installations should review their Apache HTTP virtual-host configuration and ensure that the HTTPS redirect destination ends with a trailing slash:<br /> <br /> Redirect permanent / https://misp.example/<br /> <br /> After updating the configuration, validate it with apachectl configtest and reload or restart Apache for the change to take effect

`Element.findall()` and fully-consumed `Element.iterfind()` exhibit `O(n^2)` time complexity when using XPath index predicates (e.g. `[1]`, `[last()]`, `[last()-N]`) on XML documents with many same-tag siblings. `Element.find()` is only affected when the first match is near the end  of the sibling list, such as with `[last()]` or `[last()-N]`;  `.//item[1]` short-circuits after the first match.

Deserialization of Untrusted Data (CWE-502) in the Tribes-based clustering component<br /> <br />  in Apache Software Foundation Apache Axis2/Java through 2.0.0 on Apache Tomcat<br /> <br />  (only when Tribes clustering is enabled, which is off by default) allows an<br /> <br />  unauthenticated remote attacker with network access to the clustering port to<br /> <br />  execute arbitrary code via a crafted serialized Java object delivered to the cluster<br /> <br />  channel and deserialized in<br /> <br />  org.apache.axis2.clustering.tribes.Axis2ChannelListener#messageReceived. Users are<br /> <br />  recommended to upgrade to version 2.0.1, which fixes this issue by removing the<br /> <br />  clustering feature entirely.

Uncontrolled Resource Consumption vulnerability in Apache Tomcat&amp;#39;s WebSocket chat example.<br /> <br /> This issue affects Apache Tomcat: from 11.0.0-M20 through 11.0.24, from 10.1.24 through 10.1.57, from 9.0.89 through 9.0.120. Users who have followed the security guidance to remove the examples web application are not affected by this issue.<br /> <br /> Users are recommended to remove the examples web application or to upgrade to version 11.0.25, 10.1.58 or 9.0.121 (when released), which fix the issue.

Anchore Enterprise versions from 5.11.0 to 5.27.1 and 6.0.0 contain an improper privilege escalation vulnerability in the user management API. An authenticated attacker who is able to access the Anchore Enterprise API could issue an API call capable of modifying user permissions to gain access to additional resources and operations. It is not possible to grant the system-admin role, but a read only user could be granted write access. This issue is fixed in Anchore Enterprise 5.27.2 and 6.0.1.
