Description
Improper Restriction of Rendered UI Layers or Frames in GitHub repository pyload/pyload prior to 0.5.0b3.dev33.
Affected versions
PyPI
| Package | Vulnerable | Fixed in |
|---|---|---|
| pyload-ng | < 0.5.0b3.dev33 |
0.5.0b3.dev33 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
pyload-ng PyPI → 0.5.0b3.dev33
- pip
pip install --upgrade "pyload-ng>=0.5.0b3.dev33"- poetry
poetry add "pyload-ng>=0.5.0b3.dev33"- uv
uv add "pyload-ng>=0.5.0b3.dev33"

Weakness
CWE-1021: Improper Restriction of Rendered UI Layers or Frames
The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain.
How to prevent it
- Implementation: The use of X-Frame-Options allows developers of web content to restrict the usage of their application within the form of overlays, frames, or iFrames. The developer can indicate from which domains can frame the content. The concept of X-Frame-Options is well documented, but implementation of this protection mechanism is in development to cover gaps. There is a need for allowing frames from multiple domains.
- Implementation: A developer can use a "frame-breaker" script in each page that should not be framed. This is very helpful for legacy browsers that do not support X-Frame-Options security feature previously mentioned. It is also important to note that this tactic has been circumvented or bypassed. Improper usage of frames can persist in the web application through nested frames. The "frame-breaking" script does not intuitively account for multiple nested frames that can be presented to the user.
- Implementation: This defense-in-depth technique can be used to prevent the improper usage of frames in web applications. It prioritizes the valid sources of data to be loaded into the application through the usage of declarative policies. Based on which implementation of Content Security Policy is in use, the developer should use the "frame-ancestors" directive or the "frame-src" directive to mitigate this weakness. Both directives allow for the placement of restrictions when it comes to allowing embedded content.
- Implementation: In addition to frames or iframes as previously mentioned, the web application is expected to place restrictions on whether it is allowed to be rendered within objects, embed, or applet elements.
