Which packages are affected by CVE-2024-1561?

CVE-2024-1561 affects the following packages: gradio (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2024-1561?

Update gradio to version 4.13.0 or later. Run your dependency manager's update command and verify no transitive dependencies pin the vulnerable version. Use O3 Security's SCA scanner to confirm the fix is applied across your entire dependency tree.

Is CVE-2024-1561 actively exploited in the wild?

Yes. There are 3 known exploit references for CVE-2024-1561, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2024-1561?

CVE-2024-1561 has an EPSS (Exploit Prediction Scoring System) score of 93.4%, placing it in the 100th 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. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

What type of vulnerability is CVE-2024-1561?

CVE-2024-1561 is classified as CWE-29 (CWE-29). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Is there exploit tooling available for CVE-2024-1561?

A Nuclei detection template exists for CVE-2024-1561, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2024-1561 published, and has it been updated?

CVE-2024-1561 was published on April 16, 2024 and was last updated on March 14, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

An issue was discovered in gradio-app/gradio, where the /component_server endpoint improperly allows the invocation of any method on a Component class with attacker-controlled arguments. Specifically, by exploiting the move_resource_to_block_cache() method of the Block class, an attacker can copy any file on the filesystem to a temporary directory and subsequently retrieve it. This vulnerability enables unauthorized local file read access, posing a significant risk especially when the application is exposed to the internet via launch(share=True), thereby allowing remote attackers to read files on the host machine. Furthermore, gradio apps hosted on huggingface.co are also affected, potentially leading to the exposure of sensitive information such as API keys and credentials stored in environment variables.
