Chainguard: multiple open-webui packages: security update to 0.12.3-r16

high Tenable Cloud Security Plugin ID 478178

Description

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

 - joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption
 (JOSE) standards. Prior to 1.7.5, joserfc.jwe.decrypt_json() accepts a JWE General JSON Serialization
 recipients array without a count limit and calls decrypt_cek() for every entry. An unauthenticated
 attacker who can submit a JWE to an endpoint using an RSA key-management algorithm can choose the number
 of private-key decryption operations performed by one request. The verify_all_recipients option does not
 reduce this work because the affected loop processes every recipient before consulting that setting,
 allowing repeated requests to exhaust service CPU without affecting confidentiality or integrity. This
 issue is fixed in version 1.7.5. (CVE-2026-119283)

Solution

Update the open-webui library and its related packages to version 0.12.3-r16 or later.
