CVSS: 5.7EPSS: 0%CPEs: 2EXPL: 0CVE-2023-6944 – Rhdh: catalog-import function leaks credentials to frontend
https://notcve.org/view.php?id=CVE-2023-6944
A flaw was found in the Red Hat Developer Hub (RHDH). The catalog-import function leaks GitLab access tokens on the frontend when the base64 encoded GitLab token includes a newline at the end of the string. The sanitized error can display on the frontend, including the raw access token. Upon gaining access to this token and depending on permissions, an attacker could push malicious code to repositories, delete resources in Git, revoke or generate new keys, and sign code illegitimately.

CVSS: 9.9EPSS: 0%CPEs: 1EXPL: 0CVE-2023-35926 – Insecure sandbox in Backstage Scaffolder plugin
https://notcve.org/view.php?id=CVE-2023-35926
Backstage is an open platform for building developer portals. The Backstage scaffolder-backend plugin uses a templating library that requires sandbox, as it by design allows for code injection. The library used for this sandbox so far has been `vm2`, but in light of several past vulnerabilities and existing vulnerabilities that may not have a fix, the plugin has switched to using a different sandbox library. A malicious actor with write access to a registered scaffolder template could manipulate the template in a way that allows for remote code execution on the scaffolder-backend instance. This was only exploitable in the template YAML definition itself and not by user input data. • https://github.com/backstage/backstage/commit/fb7375507d56faedcb7bb3665480070593c8949a https://github.com/backstage/backstage/releases/tag/v1.15.0 https://github.com/backstage/backstage/security/advisories/GHSA-wg6p-jmpc-xjmr • CWE-94: Improper Control of Generation of Code ('Code Injection') •
CVSS: 6.8EPSS: 0%CPEs: 3EXPL: 0CVE-2023-25571 – Backstage has XSS Vulnerability in Software Catalog
https://notcve.org/view.php?id=CVE-2023-25571
Backstage is an open platform for building developer portals. `@backstage/catalog-model` prior to version 1.2.0, `@backstage/core-components` prior to 0.12.4, and `@backstage/plugin-catalog-backend` prior to 1.7.2 are affected by a cross-site scripting vulnerability. This vulnerability allows a malicious actor with access to add or modify content in an instance of the Backstage software catalog to inject script URLs in the entities stored in the catalog. If users of the catalog then click on said URLs, that can lead to an XSS attack. This vulnerability has been patched in both the frontend and backend implementations. The default `Link` component from `@backstage/core-components` version 1.2.0 and greater will now reject `javascript:` URLs, and there is a global override of `window.open` to do the same. • https://github.com/backstage/backstage/commit/3d1371954512f7fa8bd0e2d357e00eada2c3e8a8 https://github.com/backstage/backstage/security/advisories/GHSA-7hv8-3fr9-j2hv • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-84: Improper Neutralization of Encoded URI Schemes in a Web Page •
CVSS: 6.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-41151 – Path Traversal in @backstage/plugin-scaffolder-backend
https://notcve.org/view.php?id=CVE-2021-41151
Backstage is an open platform for building developer portals. In affected versions A malicious actor could read sensitive files from the environment where Scaffolder Tasks are run. The attack is executed by crafting a custom Scaffolder template with a `github:publish:pull-request` action and a particular source path. When the template is executed the sensitive files would be included in the published pull request. This vulnerability is mitigated by the fact that an attacker would need access to create and register templates in the Backstage catalog, and that the attack is very visible given that the exfiltration happens via a pull request. • https://github.com/backstage/backstage/commit/6968962c920508eae19a4c1c200fa2c8980a4006 https://github.com/backstage/backstage/security/advisories/GHSA-pvv8-8fx9-h673 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-32662 – TechDocs mkdocs.yml path traversal
https://notcve.org/view.php?id=CVE-2021-32662
Backstage is an open platform for building developer portals, and techdocs-common contains common functionalities for Backstage's TechDocs. In `@backstage/techdocs-common` versions prior to 0.6.3, a malicious actor could read sensitive files from the environment where TechDocs documentation is built and published by setting a particular path for `docs_dir` in `mkdocs.yml`. These files would then be available over the TechDocs backend API. This vulnerability is mitigated by the fact that an attacker would need access to modify the `mkdocs.yml` in the documentation source code, and would also need access to the TechDocs backend API. The vulnerability is patched in the `0.6.3` release of `@backstage/techdocs-common`. • https://github.com/backstage/backstage/commit/8cefadca04cbf01d0394b0cb1983247e5f1d6208 https://github.com/backstage/backstage/releases/tag/release-2021-05-27 https://github.com/backstage/backstage/security/advisories/GHSA-pgf8-28gg-vpr6 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
