### Impact A discovered oEmbed or image URL can bypass the `url_preview_url_blacklist` setting potentially allowing server side request forgery or bypassing network policies. Impact is limited to IP addresses allowed by the `url_preview_ip_range_blacklist` setting (by default this only allows public IPs) and by the limited information returned to the client: * For discovered oEmbed URLs, any non-JSON response or a JSON response which includes non-oEmbed information is discarded. * For discovered image URLs, any non-image response is discarded. Systems which have URL preview disabled (via the `url_preview_enabled` setting) or have not configured a `url_preview_url_blacklist` are not affected. Because of the uncommon configuration required, the limited information a malicious user, and the amount of guesses/time the attack would need; the severity is rated as low. ### Patches The issue is fixed by #15601. ### Workarounds The default configuration of the `url_preview_ip_range_black...
Red Hat Security Advisory 2023-3445-01 - An update for etcd is now available for Red Hat OpenStack Platform 16.2 (Train). Issues addressed include a denial of service vulnerability.
### Impact It may be possible for a deactivated user to login when using uncommon configurations. This only applies if any of the following are true: * [JSON Web Tokens are enabled for login](https://matrix-org.github.io/synapse/latest/jwt.html) via the `jwt_config.enabled` configuration setting * The [local password database is enabled](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#password_config) via the `password_config.enabled` and `password_config.localdb_enabled` configuration settings *and* a user's password is [updated via an admin API](https://matrix-org.github.io/synapse/latest/admin_api/user_admin_api.html#create-or-modify-account) after a user is deactivated. **Note that the local password database is enabled by default**, but it is uncommon to set a user's password after they've been deactivated. Installations that are configured to only allow login via Single Sign-On (SSO) via CAS, SAML or OpenID Connect (OIDC); or via an e...
## Impact 1. A compromised instance with shared folders could sync malicious files which contain arbitrary HTML and JavaScript in the name. If the owner of another device looks over the shared folder settings and moves the mouse over the latest sync, a script could be executed to change settings for shared folders or add devices automatically. 2. Adding a new device with a malicious name could embed HTML or JavaScript inside parts of the page. ## Risk As long as trusted devices are used, the risk is low. Additionally, the web GUI is not used that often in daily use which reduces the likelihood of exploitation. ## Details ### 1. Field "Latest Change" * Open the web GUI at [http://127.0.0.1:8384/](http://127.0.0.1:8384/). * Create/Delete a file named ```<img src=a onerror=alert(123)>``` and sync it to the other instance. * Move your mouse over the latest change to trigger the tooltip. <img width="834" alt="latest-change" src="https://user-images.githubusercontent.com/9484134/2050...
