Real-World Exposure
org.jenkins-ci.plugins:gogs-webhookReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Jenkins Gogs Plugin provides a webhook endpoint at /gogs-webhook that can be used to trigger builds of jobs. In Gogs Plugin 1.0.15 and earlier, an option to specify a Gogs secret for this webhook is provided, but not enabled by default.
This allows unauthenticated attackers to trigger builds of jobs corresponding to the attacker-specified job name.
Additionally, the output of the webhook endpoint includes whether a job corresponding to the attacker-specified job name exists, even if the attacker has no permission to access it.
As of publication of this advisory, there is no fix.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:gogs-webhook, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of org.jenkins-ci.plugins:gogs-webhook for CVE-2023-40348. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
