Check this codebase for CVE-2025-22872 and fix it if it is affected.
What it is: CVE-2025-22872 is a medium-severity cross-site scripting vulnerability in golang.org/x/net/html, published on 16 Apr 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-22872 in the wild and no public exploit code.
Affected packages and fixed versions:
- golang.org/x/net (Go): affected all versions; fixed in 0.38.0
- golang.org/x/net (Go): affected all versions; fixed in 0.38.0
- golang.org/x/net (Go): affected all versions; fixed in 0.38.0
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.

What is CVE-2025-22872?
CVE-2025-22872 is a medium-severity cross-site scripting vulnerability in golang.org/x/net/html, published on 16 Apr 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The tokenizer incorrectly interprets tags with unquoted attribute values that end with a solidus character (/) as self-closing. When directly using Tokenizer, this can result in such tags incorrectly being marked as self-closing, and when using the Parse functions, this can result in content following such tags as being placed in the wrong scope during DOM construction, but only when tags are in foreign content (e.g. <math>, <svg>, etc contexts).
