## What is GHSA-593m-55hh-j8gv?

GHSA-593m-55hh-j8gv is a vulnerability in @sentry/browser, published on 3 Oct 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

### Impact
In case a Prototype Pollution vulnerability is present in a user's application or bundled libraries, the Sentry SDK could potentially serve as a gadget to exploit that vulnerability. The exploitability depends on the specific details of the underlying Prototype Pollution issue.

> [!NOTE]
> This advisory does not indicate the presence of a Prototype Pollution within the Sentry SDK itself. Users are strongly advised to first address any Prototype Pollution vulnerabilities in their application, as they pose a more critical security risk.

### Patches
The issue was patched in all Sentry JavaScript SDKs starting from the [8.33.0](https://github.com/getsentry/sentry-javascript/releases/tag/8.33.0) version.
Also, the fix was backported to SDK v7 in [7.119.1](https://github.com/getsentry/sentry-javascript/releases/tag/7.119.1).

Affected packages and fixed versions:
- @sentry/browser (npm): affected all versions; fixed in 7.119.1
- @sentry/browser (npm): affected all versions; fixed in 7.119.1

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.
