CVE-2026-44346

BentoML is a Python library for building online serving systems optimized for AI apps and model inference. Prior to 1.4.39, a malicious bentofile.yaml containing a newline-injected value in envs.name produces unquoted RUN directives in the BentoML-generated Dockerfile. When the victim runs bentom...

BentoML is a Python library for building online serving systems optimized for AI apps and model inference. Prior to 1.4.39, src/bentoml/internal/container/frontend/dockerfile/templates/basev2.j2 interpolates docker.baseimage raw with no escaping, newline filtering, or validation. A malicious...

CVE-2026-40610

BentoML is a Python library for building online serving systems optimized for AI apps and model inference. In versions 1.4.38 and prior, the build packaging workflow follows attacker-controlled symlinks inside the build context and copies the referenced file contents into the generated Bento...

CVE-2026-35044

Summary (CVE-2026-35044) BentoML prior to 1.4.38 is vulnerable to server-side template injection via an unsandboxed Jinja2 environment used to render Dockerfile templates during containerization. attacker-controlled templates can execute arbitrary Python on the host during template rendering (not...

BentoML: SSTI via Unsandboxed Jinja2 in Dockerfile Generation

Summary The Dockerfile generation function generatecontainerfile in src/bentoml/internal/container/generate.py uses an unsandboxed jinja2.Environment with the jinja2.ext.do extension to render user-provided dockerfiletemplate files. When a victim imports a malicious bento archive and runs bentoml...

BentoML < 1.4.36 Arbitrary File Write

The version of the BentoML library installed on the remote host is prior to 1.4.36. It is, therefore, affected by an arbitrary file write vulnerability: - The safeextracttarfile function validates that each tar member's path is within the destination directory, but for symlink members it only...

CVE-2026-27905

BentoML is a Python library for building online serving systems optimized for AI apps and model inference. Prior to 1.4.36, the safeextracttarfile function validates that each tar member's path is within the destination directory, but for symlink members it only validates the symlink's own path,...

GHSA-M6W7-QV66-G3MF BentoML Vulnerable to Arbitrary File Write via Symlink Path Traversal in Tar Extraction

Arbitrary File Write via Symlink Path Traversal in Tar Extraction Summary The safeextracttarfile function validates that each tar member's path is within the destination directory, but for symlink members it only validates the symlink's own path, not the symlink's target. An attacker can create a...

BentoML < 1.4.34 Path Traversal

The version of the BentoML library installed on the remote host is prior to 1.4.34. It is, therefore, affected by a path traversal vulnerability: - BentoML's bentofile.yaml configuration allows path traversal attacks through multiple file path fields description, docker.setupscript,...

The vulnerability of the BentoML library, related to insufficient validation of requests on the server side, allows a attacker to execute an SSRF attack.

The vulnerability of the BentoML library is related to insufficient validation of requests on the server side. Exploiting this vulnerability could allow a malicious actor to execute an SSRF attack remotely...

Server Side Request Forgery (SSRF)

bentoml is vulnerable to Server-Side Request Forgery SSRF. The vulnerability is due to the file upload handlers automatically downloading files from user-provided URLs without validating their targets, which allows an attacker to make the server send arbitrary HTTP requests to internal or...

BentoML 1.4.x < 1.4.19 Server-Side Request Forgery

According to its banner, the version of BentoML running on the remote host is 1.4.x 1.4.8. It is, therefore, affected by a Server-Side Request Forgery SSRF vulnerability in File Upload Processing. Note that the scanner has not tested for these issues but has instead relied only on the application...

BentoML 1.3.4 < 1.4.3 Insecure Deserialization

According to its banner, the version of BentoML running on the remote host is 1.3.4 1.4.3. It is, therefore, affected by an Insecure Deserialization vulnerability through data flow analysis Note that the scanner has not tested for these issues but has instead relied only on the application's...
