CVE-2026-35582 nsa vulnerability CVSS: 0 18 Apr 2026, 02:16 UTC

Emissary is a P2P based data-driven workflow engine. In versions 8.42.0 and below, Executrix.getCommand() is vulnerable to OS command injection because it interpolates temporary file paths into a /bin/sh -c shell command string without any escaping or input validation. The IN_FILE_ENDING and OUT_FILE_ENDING configuration keys flow directly into these paths, allowing a place author who can write or modify a .cfg file to inject arbitrary shell metacharacters that execute OS commands in the JVM process's security context. The framework already sanitizes placeName via an allowlist before embedding it in the same shell string, but applies no equivalent sanitization to file ending values. No runtime privileges beyond place configuration authorship, and no API or network access, are required to exploit this vulnerability. This is a framework-level defect with no safe mitigation available to downstream implementors, as Executrix provides neither escaping nor documented preconditions against metacharacters in file ending inputs. This issue has been fixed in version 8.43.0.

CVE-2026-35583 nsa vulnerability CVSS: 0 07 Apr 2026, 17:16 UTC

Emissary is a P2P based data-driven workflow engine. Prior to 8.39.0, the configuration API endpoint (/api/configuration/{name}) validated configuration names using a blacklist approach that checked for \, /, .., and trailing .. This could potentially be bypassed using URL-encoded variants, double-encoding, or Unicode normalization to achieve path traversal and read configuration files outside the intended directory. This vulnerability is fixed in 8.39.0.

CVE-2026-35581 nsa vulnerability CVSS: 0 07 Apr 2026, 17:16 UTC

Emissary is a P2P based data-driven workflow engine. Prior to 8.39.0, the Executrix utility class constructed shell commands by concatenating configuration-derived values — including the PLACE_NAME parameter — with insufficient sanitization. Only spaces were replaced with underscores, allowing shell metacharacters (;, |, $, `, (, ), etc.) to pass through into /bin/sh -c command execution. This vulnerability is fixed in 8.39.0.

CVE-2026-35580 nsa vulnerability CVSS: 0 07 Apr 2026, 17:16 UTC

Emissary is a P2P based data-driven workflow engine. Prior to 8.39.0, GitHub Actions workflow files contained shell injection points where user-controlled workflow_dispatch inputs were interpolated directly into shell commands via ${{ }} expression syntax. An attacker with repository write access could inject arbitrary shell commands, leading to repository poisoning and supply chain compromise affecting all downstream users. This vulnerability is fixed in 8.39.0.

CVE-2026-35571 nsa vulnerability CVSS: 0 07 Apr 2026, 16:16 UTC

Emissary is a P2P based data-driven workflow engine. Prior to 8.39.0, Mustache navigation templates interpolated configuration-controlled link values directly into href attributes without URL scheme validation. An administrator who could modify the navItems configuration could inject javascript: URIs, enabling stored cross-site scripting (XSS) against other authenticated users viewing the Emissary web interface. This vulnerability is fixed in 8.39.0.

CVE-2023-22671 nsa vulnerability CVSS: 0 06 Jan 2023, 07:15 UTC

Ghidra/RuntimeScripts/Linux/support/launch.sh in NSA Ghidra through 10.2.2 passes user-provided input into eval, leading to command injection when calling analyzeHeadless with untrusted input.

CVE-2021-32639 nsa vulnerability CVSS: 6.5 02 Jul 2021, 16:15 UTC

Emissary is a P2P-based, data-driven workflow engine. Emissary version 6.4.0 is vulnerable to Server-Side Request Forgery (SSRF). In particular, the `RegisterPeerAction` endpoint and the `AddChildDirectoryAction` endpoint are vulnerable to SSRF. This vulnerability may lead to credential leaks. Emissary version 7.0 contains a patch. As a workaround, disable network access to Emissary from untrusted sources.

CVE-2021-32647 nsa vulnerability CVSS: 6.5 01 Jun 2021, 14:15 UTC

Emissary is a P2P based data-driven workflow engine. Affected versions of Emissary are vulnerable to post-authentication Remote Code Execution (RCE). The [`CreatePlace`](https://github.com/NationalSecurityAgency/emissary/blob/30c54ef16c6eb6ed09604a929939fb9f66868382/src/main/java/emissary/server/mvc/internal/CreatePlaceAction.java#L36) REST endpoint accepts an `sppClassName` parameter which is used to load an arbitrary class. This class is later instantiated using a constructor with the following signature: `<constructor>(String, String, String)`. An attacker may find a gadget (class) in the application classpath that could be used to achieve Remote Code Execution (RCE) or disrupt the application. Even though the chances to find a gadget (class) that allow arbitrary code execution are low, an attacker can still find gadgets that could potentially crash the application or leak sensitive data. As a work around disable network access to Emissary from untrusted sources.

CVE-2021-32634 nsa vulnerability CVSS: 6.5 21 May 2021, 18:15 UTC

Emissary is a distributed, peer-to-peer, data-driven workflow framework. Emissary 6.4.0 is vulnerable to Unsafe Deserialization of post-authenticated requests to the [`WorkSpaceClientEnqueue.action`](https://github.com/NationalSecurityAgency/emissary/blob/30c54ef16c6eb6ed09604a929939fb9f66868382/src/main/java/emissary/server/mvc/internal/WorkSpaceClientEnqueueAction.java) REST endpoint. This issue may lead to post-auth Remote Code Execution. This issue has been patched in version 6.5.0. As a workaround, one can disable network access to Emissary from untrusted sources.

NSA Ghidra before 9.0.2 is vulnerable to DLL hijacking because it loads jansi.dll from the current working directory.

CVE-2019-17664 nsa vulnerability CVSS: 4.4 16 Oct 2019, 20:15 UTC

NSA Ghidra through 9.0.4 uses a potentially untrusted search path. When executing Ghidra from a given path, the Java process working directory is set to this path. Then, when launching the Python interpreter via the "Ghidra Codebrowser > Window > Python" option, Ghidra will try to execute the cmd.exe program from this working directory.

CVE-2019-16941 nsa vulnerability CVSS: 6.8 28 Sep 2019, 16:15 UTC

NSA Ghidra through 9.0.4, when experimental mode is enabled, allows arbitrary code execution if the Read XML Files feature of Bit Patterns Explorer is used with a modified XML document. This occurs in Features/BytePatterns/src/main/java/ghidra/bitpatterns/info/FileBitPatternInfoReader.java. An attack could start with an XML document that was originally created by DumpFunctionPatternInfoScript but then directly modified by an attacker (for example, to make a java.lang.Runtime.exec call).

CVE-2019-13625 nsa vulnerability CVSS: 9.4 17 Jul 2019, 03:15 UTC

NSA Ghidra before 9.0.1 allows XXE when a project is opened or restored, or a tool is imported, as demonstrated by a project.prp file.

CVE-2019-13623 nsa vulnerability CVSS: 6.8 17 Jul 2019, 03:15 UTC

In NSA Ghidra before 9.1, path traversal can occur in RestoreTask.java (from the package ghidra.app.plugin.core.archive) via an archive with an executable file that has an initial ../ in its filename. This allows attackers to overwrite arbitrary files in scenarios where an intermediate analysis result is archived for sharing with other persons. To achieve arbitrary code execution, one approach is to overwrite some critical Ghidra modules, e.g., the decompile module.

CVE-2001-0073 nsa vulnerability CVSS: 2.1 12 Feb 2001, 05:00 UTC

Buffer overflow in the find_default_type function in libsecure in NSA Security-enhanced Linux, which may allow attackers to modify critical data in memory.
