GHSA-cgvv-3455-824j: Moodle Session Fixation allows unauthenticated users to hijack sessions via sesskey parameter

A session fixation vulnerability in Moodle 3.x through 3.11.18 allows unauthenticated attackers to hijack user sessions via the sesskey parameter. The sesskey can be obtained without authentication and reused within the OAuth2 login flow, resulting in the victim's session being linked to the attacker's. Successful exploitation results in full account takeover. According to the Moodle Releases page, "Bug fixes for security issues in 3.11.x ended 11 December 2023."

GHSA-pgvc-6h2p-q4f6: Umbraco CMS disclosure of configured password requirements

### Impact Via a request to an anonymously authenticated endpoint it's possible to retrieve information about the configured password requirements. The information available is limited but would perhaps give some additional detail useful for someone attempting to brute force derive a user's password. The vulnerability can be found in the supported Umbraco versions 10 and 13. It was not exposed in Umbraco 7 or 8, nor in 14 or higher versions. ### Patches Patched in 10.8.11 and 13.9.2

GHSA-wj44-9vcg-wjq7: Gogs allows deletion of internal files which leads to remote command execution

### Summary Due to the insufficient patch for the CVE-2024-39931, it's still possible to delete files under the `.git` directory and achieve remote command execution. ### Details In the patch for CVE-2024-39931, the following check is added: https://github.com/gogs/gogs/commit/77a4a945ae9a87f77e392e9066b560edb71b5de9 ```diff + // 🚨 SECURITY: Prevent uploading files into the ".git" directory + if isRepositoryGitPath(opts.TreePath) { + return errors.Errorf("bad tree path %q", opts.TreePath) + } ``` While the above code snippet checks if the specified path is a `.git` directory, there are no checks for symbolic links in the later steps. So, by creating a symbolic link that points to the `.git` directory, an attacker can still delete arbitrary files in the `.git` directory and achieve remote command execution. ### Impact Unprivileged user accounts can execute arbitrary commands on the Gogs instance with the privileges of the account specified by `RUN_USER` in the configuration.
