## What is CVE-2020-7676?

CVE-2020-7676 is a medium-severity cross-site scripting vulnerability in angular.js, published on 8 Jun 2020. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

angular.js prior to 1.8.0 allows cross site scripting. The regex-based input HTML replacement may turn sanitized code into unsanitized one. Wrapping "<option>" elements in "<select>" ones changes parsing behavior, leading to possibly unsanitizing code.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Check this codebase for CVE-2020-7676 and fix it if it is affected.

What it is: CVE-2020-7676 is a medium-severity cross-site scripting vulnerability in angular.js, published on 8 Jun 2020. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2020-7676 in the wild and no public exploit code.

Affected packages and fixed versions:
- angular (npm): affected all versions; fixed in 1.8.0
- angular (npm): affected all versions; fixed in 1.8.0

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
