How severe is CVE-2023-49654?

CVE-2023-49654 has a CVSS score of 7.1/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2023-49654?

CVE-2023-49654 affects the following packages: org.jenkins-ci.plugins:matlab (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-49654?

Update org.jenkins-ci.plugins:matlab to 2.11.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-49654 is resolved across your whole dependency graph.

How do I detect CVE-2023-49654 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:matlab, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2023-49654 if there is no patch (or I can't update yet)?

Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.

Is CVE-2023-49654 actively exploited in the wild?

No public exploit code has been indexed for CVE-2023-49654 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2023-49654?

CVE-2023-49654 has an EPSS (Exploit Prediction Scoring System) score of 0.8%, placing it in the 56th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2023-49654?

CVE-2023-49654 is classified as CWE-862 (CWE-862). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2023-49654 published, and has it been updated?

CVE-2023-49654 was published on November 29, 2023 and was last updated on February 16, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-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 MATLAB Plugin determines whether a user-specified directory on the Jenkins controller is the location of a MATLAB installation by parsing an XML file in that directory.

MATLAB Plugin 2.11.0 and earlier does not perform permission checks in several HTTP endpoints implementing related form validation.

Additionally, these HTTP endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

Additionally, the plugin does not configure its XML parser to prevent XML external entity (XXE) attacks. This allows attackers able to create files on the Jenkins controller file system to have Jenkins parse a crafted XML document that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

MATLAB Plugin 2.11.1 configures its XML parser to prevent XML external entity (XXE) attacks.

Additionally, POST requests and Item/Configure permission are required for the affected HTTP endpoints.
