Technical description

Blinko through 1.8.8 allows directory traversal, overwriting startup files as root, via installPlugin. It builds the plugin install path from an unsanitized name in server/routerTrpc/plugin.ts, and the plugin.installPlugin tRPC procedure is open to any authenticated user. Thus, a name containing ../ sequences writes the downloaded plugin files outside the plugins directory. Because the official Docker image runs as root, an authenticated attacker overwrites a root-owned startup file and achieves remote code execution as root. Self-registration for an account may be possible.

CVE-2026-92533—

——9Path traversal vulnerability in the BugTracker.NET file download component. The parameter used to specify the file name does not properly validate user-supplied paths. An authenticated remote attacker could enter a manipulated path to access files located outside the intended directory. Successful exploitation could allow the attacker to read system files accessible to the account used by the application.14d CVE-2026-1053147.5 HIG

——18Papermerge 3.5.3 allows remote code execution by a standard user via directory traversal in a /api/documents/upload call. A Python .pth file can be written to site-packages, and its code is executed upon the next start of the Python interpreter.15d CVE-2026-1049942.5 LOW

——3Trivy before 0.71.0 allows directory traversal in Terraform filesystem functions when they try to access pathnames above the scan root. The risk occurs when using misconf scanning on untrusted input (e.g., upon a third-party pull request that contains a Terraform configuration), if sensitive data can be found at those unintended pathnames, and an adversary can then view a sensitive data value within scan output.16d CVE-2026-1030887.5 HIG

——16Handlebars.java before 4.5.5 allows directory traversal. In handlebars-springmvc 4.5.3 and 4.5.4, the path-containment fix for CVE-2026-63490 validates template locations as raw percent-encoded strings, whereas the template file is opened through a URL handler that percent-decodes the path. In a Spring MVC application with a file: template prefix and a request-derived view name, a percent-encoded traversal such as %2e%2e/ bypasses both the view-resolver check and the loader-side containment and reads files outside the configured template base directory.21d CVE-2026-977308.5 HIG

——19In Netgate pfSense Plus before 26.07 and pfSense CE before 2.9.0, a Local File Inclusion (LFI) vulnerability in the Dashboard (index.php) widget sequence data handling allows an authenticated attacker to execute arbitrary PHP code. To exploit this, an attacker with privileges to modify Dashboard settings and write arbitrary files to the pfSense firewall system (e.g., /tmp/test.widget.php) can submit a crafted widget sequence value containing a path traversal payload (e.g., ../../../../../../../../../../../tmp/test). The Dashboard will subsequently read and execute the arbitrary PHP file as if it were a standard widget.24d CVE-2026-34151—

——19XWiki Platform is a generic wiki platform. Prior to 17.10.5 and 18.2.0, the /skin/ action in com.xpn.xwiki.web.SkinAction can resolve double-encoded parent-directory segments outside the intended skin or web-application resource prefix when Jetty 12 or later decodes the request path. The affected lookup is replaced with Environment.getResourceAsStream(String, String), which constrains a resource to its expected prefix. An unauthenticated remote attacker can use the vulnerable behavior to read arbitrary resources permitted to the Jetty process, including WEB-INF/xwiki.cfg and, depending on deployment depth and operating-system permissions, host files. Tomcat and Jetty versions before 12 do not appear affected. This issue is fixed in versions 17.10.5 and 18.2.0.21d
