|---|---|---|---|---|---|---|
| CVE-2026-35582 | 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 pr | [email protected] | 8.8 | 0.86% | 2026-04-17 | 2026-06-17 |
| CVE-2026-35583 | 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. | [email protected] | 5.3 | 0.32% | 2026-04-07 | 2026-06-17 |
| CVE-2026-35581 | 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. | [email protected] | 7.2 | 0.56% | 2026-04-07 | 2026-06-17 |
| CVE-2026-35580 | 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. | [email protected] | 9.1 | 0.57% | 2026-04-07 | 2026-06-17 |
| CVE-2026-35571 | 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. | [email protected] | 4.8 | 0.18% | 2026-04-07 | 2026-06-17 |
| CVE-2021-32639 | 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. | [email protected] | 7.2 | 1.40% | 2021-07-02 | 2026-06-16 |
| CVE-2021-32647 | 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.

| CVE-2021-32634 | 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.

| CVE-2021-32092 | A Cross-site scripting (XSS) vulnerability in the DocumentAction component of U.S. National Security Agency (NSA) Emissary 5.9.0 allows remote attackers to inject arbitrary web script or HTML via the uuid parameter. | [email protected] | 6.1 | 0.95% | 2021-05-07 | 2026-06-16 |
| CVE-2021-32096 | The ConsoleAction component of U.S. National Security Agency (NSA) Emissary 5.9.0 allows a CSRF attack that results in injecting arbitrary Ruby code (for an eval call) via the CONSOLE_COMMAND_STRING parameter. | [email protected] | 8.8 | 0.59% | 2021-05-07 | 2026-06-16 |
