Chainguard: tensorflow-gpu-jupyter: security update to 2.21.0-r11

medium Tenable Self-Hosted Container Security Plugin ID 471648

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - fast-uri is a dependency-free RFC 3986 URI parser for Node.js, used by Fastify and ajv, that added a
 mailto scheme parser in version 4.1.3. In versions 4.1.3 and 4.1.4, the mailto parser compares each query
 field name to the reserved names to, subject, and body while the name is still percent-encoded, and
 decodes it only when storing it as a generic header, so a percent-encoded spelling of a reserved field
 name is not recognized as that field at parse time but is re-emitted as the literal field name when the
 parsed URI is serialized. An application that validates, logs, or displays the recipient list from the
 first parse and then serializes the URI and sends it can silently gain an attacker-chosen recipient, and
 the subject and body fields can be smuggled across the same roundtrip. The issue is fixed in fast-uri
 4.1.5, and users should upgrade to 4.1.5 or later. As a workaround, do not act on a mailto URI that fast-
 uri has re-serialized without first decoding and re-validating its recipient, subject, and body fields.
 (CVE-2026-86818)

Solution

Update the tensorflow-gpu-jupyter library and its related packages to version 2.21.0-r11 or later.
