GHSA-534w-937m-v7x3
CRITICALrestforce vulnerable to Improper Input Validation
Blast Radius
restforceReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects RubyGems packages — download data is not available via public APIs for these ecosystems.
Description
A flaw in how restforce constructs URLs may allow an attacker to inject additional parameters into Salesforce API requests.
Impact
This flaw is only exploitable in applications that pass user input directly to restforce's select, find, describe, update, upsert, and destroy methods.
Vulnerable code might look like:
client.select('SomeSalesForceObject', params[:some-id],
...)
In such an application, attackers could pass 0016000000MRatd/describe as a request parameter, causing the server to make a request to a different endpoint than the server is designed to handle. Since the Salesforce REST API supports overriding HTTP methods via a request parameter, an attacker could also cause the client's select() method to modify data, by passing 0016000000MRatd/?_HttpMethod=PATCH&other-query-params=....
Workarounds
If possible, applications should track salesforce IDs internally, rather than passing user-supplied IDs to salesforce. Such practice mitigates this vulnerability, and in general is desirable for ensuring strong access control.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for restforce. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update restforce to 3.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-534w-937m-v7x3 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-534w-937m-v7x3 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-534w-937m-v7x3. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-534w-937m-v7x3 in your dependencies?
O3 detects GHSA-534w-937m-v7x3 across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
