SCA: security update for serialize-javascript (GHSA-m5mm-p8h7-m29v)

low Tenable Self-Hosted Container Security Plugin ID 477231

Description

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

- Serialize JavaScript serializes JavaScript values to a superset of JSON that includes regular expressions
and functions. Prior to 7.1.3, the function-source escaping logic does not neutralize a bare closing-
script prefix when attacker-influenced function source text ends exactly at that prefix. Because each
function body is escaped independently, a delimiter supplied by surrounding serialized output can
terminate an HTML script element, and a later serialized value supplies injected markup that becomes a
live element in the page. Exploitation requires control of a serialized function's source text, such as
through a spoofed toString(). This issue is fixed in version 7.1.3. (CVE-2026-115897)

Solution

Update the serialize-javascript library and its related packages to version 7.1.3 or later.
