medium Tenable Self-Hosted Container Security Plugin ID 460839

Description

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

 - NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_charset_module module. When content
 is served or proxied through a location block with both source_charset utf-8; and a charset directive (for
 example, charset koi8-r;) configured, remote, unauthenticated attackers can send requests (in conjunction
 with conditions beyond their control) to cause a heap buffer over-read in the NGINX worker process,
 leading to limited disclosure of memory or a restart. Note: Software versions which have reached End of
 Technical Support (EoTS) are not evaluated. (CVE-2026-48142)

Solution

Update the nginx library and its related packages to version 1.26.3-3+deb13u7 or later.
