### Impact Paths checks with the `resolveSafeChildPath` utility were not exhaustive enough, leading to risk of path traversal vulnerabilities if symlinks can be injected by attackers. ### Patches Patched in `@backstage/backend-common` version `0.21.1`. Patched in `@backstage/backend-common` version `0.20.2`. Patched in `@backstage/backend-common` version `0.19.10`. ### For more information 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)
Applications that use UriComponentsBuilder to parse an externally provided URL (e.g. through a query parameter) AND perform validation checks on the host of the parsed URL may be vulnerable to a open redirect attack or to a SSRF attack if the URL is used after passing validation checks.
The ACME-challenge endpoint in Appwrite 0.5.0 through 0.12.x before 0.12.2 allows remote attackers to read arbitrary local files via ../ directory traversal. In order to be vulnerable, `APP_STORAGE_CERTIFICATES/.well-known/acme-challenge` must exist on disk. (This pathname is automatically created if the user chooses to install Let's Encrypt certificates via Appwrite.)
### Impact This security policy is with regards to a timing attack that allows users of Gradio apps to potentially guess the password of password-protected Gradio apps. This relies on the fact that string comparisons in Python terminate early, as soon as there is a string mismatch. Because Gradio apps are, by default, not rate-limited, a user could brute-force millions of guesses to figure out the correct username and password. ### Patches Yes, the problem has been patched in Gradio version 4.19.2 or higher. We have no knowledge of this exploit being used against users of Gradio applications, but we encourage all users to upgrade to Gradio 4.19.2 or higher. Fixed in: https://github.com/gradio-app/gradio/commit/e329f1fd38935213fe0e73962e8cbd5d3af6e87b
### Summary On all Label Studio versions prior to 1.11.0, data imported via file upload feature is not properly sanitized prior to being rendered within a [`Choices`](https://labelstud.io/tags/choices) or [`Labels`](https://labelstud.io/tags/labels) tag, resulting in an XSS vulnerability. ### Details Need permission to use the "data import" function. This was reproduced on Label Studio 1.10.1. ### PoC 1. Create a project.  2. Upload a file containing the payload using the "Upload Files" function.   The following are the contents of the files used in the PoC ``` { "data": { "prompt": "...
### Impact An attacker able to submit many ciphertexts against a single private key, and to get responses in real-time, could recover the private key. This vulnerability has been named KyberSlash. CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N/E:F/RL:O/RC:C ### Patches Version 0.0.6.1 and newer of PyPQC is patched. ### Workarounds No workarounds have been reported. The 0.0.6 -> 0.0.6.1 upgrade should be a drop-in replacement; it has no known breaking changes. ### References 1. This was partially patched ("KyberSlash 1") in the reference implementation by Peter Schwabe on December 1st, 2023. https://www.github.com/pq-crystals/kyber/commit/dda29cc63af721981ee2c831cf00822e69be3220 2.

### Impact All users of mjml-python who insert untrusted data into mjml templates unless that data is checked in a very strict manner. User input like `<script>` would be rendered as `<script>` in the final HTML output. The attacker must be able to control some data which is later injected in an mjml template which is then send out as email to other users. The attacker could control contents of email messages sent through the platform. ### Patches The problem has been fixed in version 0.11.0 of this library. Versions before 0.10.0 are not affected by this security issue which was added as part of commit 84c495da20a91640a1ca551ace17df7f3be644aa. ### Workarounds - Ensure that potentially untrusted user input does not contain any sequences which could be rendered as HTML. ### References - Initial issue report by @sh-at-cs in #52
### Impact A bug in permissions validation allows a user with the `ci:ReadAction` permission to skip read checks when copying an object. If they additionally have read and write permission to path in the repository, they can copy an otherwise unreadable object and read it. In order to be affected and exploitable, the following conditions must ALL occur on the same user: 1. `ci:ReadAction` enabled for the repository. Predefined policies RepoManagementRead and RepoManagementFullAccess allow this action. 2. `fs:ReadObject` and `fs:WriteObject` enabled for some path. 3. `fs:ReadObject` _not_ available for some path Such a user can use (1) to copy the unreadable object (3) to a path that they can read and write (2). At that point they can read the object copy. ### Patches Releases >= 1.12.1 fix this issue in lakeFS. ### Workarounds As a workaround, use RBAC to deny `ci:*` permissions to all users, or to all users who have limited read access. Many installations are unaffected: *...
